What to Expect During Your Exam
Exam Overview
To document the nature, severity, and functional impact of glossopharyngeal nerve neuritis for VA disability rating purposes under 38 CFR 4.124a DC 8309. The examiner will assess whether incomplete or complete paralysis features are present, characterize pain type (constant, intermittent, dull), and document all cranial nerve IX functions affected.
What the examiner evaluates:
- Type and severity of pain in the distribution of cranial nerve IX (throat, tongue base, ear, tonsil region)
- Presence and severity of dysphagia (difficulty swallowing)
- Presence and severity of dysarthria (difficulty speaking)
- Taste sensation from the posterior one-third of the tongue
- Salivary gland function (parotid) - increased or decreased salivation
- Gag reflex integrity
- Sensory deficits including numbness and paresthesias/dysesthesias in nerve distribution
- Gastrointestinal symptoms (nausea, vomiting) related to vagal co-involvement
- Functional impact on daily activities such as eating, speaking, and working
- History including etiology, onset, and course of the condition
- Any co-involvement of adjacent cranial nerves (V, VII, VIII, X, XI, XII)
- Results of relevant diagnostic studies (EMG, nerve conduction, MRI, imaging)
The examination will be conducted in person with a neurologist or physician. Cranial nerve testing will be performed including sensory testing of the pharynx and posterior tongue, gag reflex testing, and assessment of palatal movement. Bring all prior treatment records, imaging results, and a written summary of your symptoms. You have the right to request the exam be recorded in most states.
Typical duration: 30-45 minutes
Gag Reflex Testing
Integrity of the afferent arc (CN IX sensory) and efferent arc (CN X motor) of the gag reflex. Diminished or absent gag reflex supports CN IX dysfunction.
What to expect:
The examiner will touch the posterior pharyngeal wall or soft palate with a tongue depressor on each side and observe symmetry and strength of the gag response.
Key thresholds:
- Normal bilateral gag reflex — May not support a rating; document any associated pain triggered by the test
- Reduced or absent unilateral gag reflex — Supports incomplete paralysis or neuritis finding; contributes to higher rating levels
- Absent bilateral gag reflex with other symptoms — Supports severe incomplete paralysis level
Tips:
- Tell the examiner immediately if the test triggers your typical pain, numbness, or paresthesias
- Report if swallowing is painful or if the test provokes a coughing or choking episode
- Note if your gag reflex varies depending on your condition status on that day
Pain considerations: Gag reflex testing may provoke pain in CN IX neuritis. Immediately and accurately describe any pain triggered, its quality (sharp, burning, electric), location, and radiation pattern.
Posterior Tongue Taste Testing
Sensory function of the posterior one-third of the tongue, which is exclusively innervated by CN IX for taste and general sensation.
What to expect:
The examiner may apply bitter, salty, sweet, or sour solutions to the posterior tongue and ask you to identify the taste. Diminished or absent taste sensation in this region points to CN IX involvement.
Key thresholds:
- Normal taste perception posteriorly — Does not preclude rating if other CN IX symptoms are present
- Reduced taste (hypogeusia) posterior tongue — Supports sensory component of neuritis; evaluated at mild to moderate incomplete paralysis scale per 38 CFR 4.124a
- Complete loss of taste (ageusia) posterior tongue — Supports moderate level of sensory impairment under the purely sensory rule
Tips:
- Distinguish between taste loss on the back versus front of the tongue - posterior involvement is specifically CN IX
- Report whether taste disturbance is constant or intermittent and whether it has worsened over time
- Note any associated burning or painful dysgeusia in the posterior tongue area
Pain considerations: Any painful sensation during taste testing in the posterior tongue or tonsillar area is characteristic of CN IX neuritis and should be described to the examiner in detail.
Pharyngeal Sensory Testing
Sensory innervation of the pharynx (tonsil, soft palate, posterior pharyngeal wall) by CN IX. Numbness, reduced sensation, or painful hypersensitivity in this region is diagnostically significant.
What to expect:
The examiner may lightly touch the pharyngeal walls and tonsillar region to assess sensation. Asymmetry or absent sensation is recorded. They may also observe uvular deviation.
Key thresholds:
- Reduced or absent pharyngeal sensation — Sensory-only impairment is rated at mild to moderate incomplete paralysis level per 38 CFR 4.124a
- Pain provoked in tonsillar fossa or posterior pharynx on light touch — Supports neuritis/neuralgia diagnosis and may support higher incomplete paralysis level when combined with other findings
Tips:
- Report all locations where you experience abnormal sensation - throat, ear, back of tongue, tonsil region
- Describe whether abnormal sensations are present at rest versus only when triggered by swallowing or speaking
- Note if cold liquids, hot foods, or yawning trigger your symptoms
Pain considerations: The examiner needs to know whether routine pharyngeal contact (swallowing, speaking, yawning) reliably triggers pain. This distinguishes neuralgia from incidental discomfort and is critical for accurate rating.
Swallowing Function Assessment (Dysphagia Evaluation)
The motor contribution of CN IX to the pharyngeal phase of swallowing. Difficulty swallowing (dysphagia) severity directly affects the functional rating.
What to expect:
The examiner may ask you to swallow water or observe your swallowing mechanism. They will ask about your history of dysphagia, choking episodes, aspiration, and diet modifications.
Key thresholds:
- Mild dysphagia - occasional difficulty, no diet change — Supports mild incomplete paralysis level
- Moderate dysphagia - frequent difficulty, soft diet required — Supports moderate incomplete paralysis level
- Severe dysphagia - liquid diet, aspiration risk, weight loss — Supports severe incomplete paralysis level
Tips:
- Describe your worst episodes of swallowing difficulty, not just your average day
- Tell the examiner if you have ever choked or aspirated food/liquid
- Report any weight loss related to swallowing problems
- Note whether pain occurs during swallowing and where it radiates
Pain considerations: Odynophagia (painful swallowing) is a hallmark of CN IX neuritis. Clearly describe the character (stabbing, burning, electric), location, and radiation of any swallowing-related pain to the ear, jaw, or neck.
Cranial Nerve Co-involvement Screening
Whether adjacent cranial nerves (VII facial, VIII vestibulocochlear, X vagus, XI spinal accessory, XII hypoglossal) are concurrently affected, which may indicate a broader lesion and affect overall rating.
What to expect:
The examiner will systematically assess all cranial nerves. This includes facial movement (CN VII), hearing (CN VIII), voice quality and palate (CN X), shoulder shrug (CN XI), and tongue movement (CN XII).
Key thresholds:
- Isolated CN IX involvement only — Rated under DC 8309 alone
- Multiple cranial nerve involvement confirmed — May support additional separate ratings for each affected nerve; inform examiner of all symptoms across all cranial nerves
Tips:
- Report any hoarseness or voice changes (CN X involvement)
- Report any hearing changes, tinnitus, or balance problems (CN VIII involvement)
- Report any facial weakness or numbness (CN VII/V involvement)
- Each separately rated cranial nerve condition adds to your overall disability picture
Pain considerations: Pain radiating to the ear (otalgia) may reflect CN IX distribution to the middle ear via Jacobson's nerve. Clearly describe all locations where you experience pain, numbness, or abnormal sensation.
Rating Criteria Breakdown
| Rating % | Criteria | Key Symptoms |
|---|---|---|
| 40% | Severe incomplete paralysis of CN IX (neuritis with organic changes). This is the maximum evaluation for neuritis per 38 CFR 4.123, applicable when neuritis is characterized by loss of reflexes, muscle atrophy, sensory disturbances, AND constant pain. All four organic change criteria must be documented to support this maximum level. |
CFR: 38 CFR 4.123: Neuritis characterized by loss of reflexes, muscle atrophy, sensory disturbances, and constant pain is rated on the scale for the nerve involved. The maximum evaluation for neuritis is the evaluation provided for severe incomplete paralysis of the affected nerve. |
| 20% | Moderate incomplete paralysis of CN IX (neuritis). Symptoms are more persistent, affect a larger area of CN IX distribution, and begin to interfere with functional activities. Under M21-1 guidance, this is the maximum level that may be assigned for neuritis without organic changes (loss of reflexes, muscle atrophy, constant pain), and the maximum for purely sensory cases in the most significant and disabling presentations. Neuralgia (DC 8407) is also capped at this level. |
CFR: 38 CFR 4.124a: The maximum evaluation for neuritis (without organic changes) is generally the evaluation level for moderate incomplete paralysis. M21-1 reserves the moderate level for the most significant and disabling cases of sensory-only involvement. |
| 10% | Mild incomplete paralysis of CN IX (neuritis, sensory-only or minimal functional impairment). Under 38 CFR 4.124a and M21-1 guidance, when impairment is wholly sensory, the evaluation assigned should be that specified for mild, or at most moderate, incomplete paralysis. The mild level applies when sensory symptoms are recurrent but not continuous, reflect a lower medical grade of impairment, and/or affect a smaller area within the nerve distribution. |
CFR: 38 CFR 4.124a notes that when impairment is wholly sensory, the evaluation should be that specified for the mild or at most the moderate degree of incomplete paralysis. Mild level is appropriate when sensory symptoms are recurrent but not continuous. |

CFR: 38 CFR 4.124a notes that when impairment is wholly sensory, the evaluation should be that specified for the mild or at most the moderate degree of incomplete paralysis. Mild level is appropriate when sensory symptoms are recurrent but not continuous.
How to Describe Your Symptoms
Pain Character and Distribution
How to describe:
Describe the quality of the pain (sharp, stabbing, burning, electric shock-like, dull, aching), where it starts (throat, tonsil area, base of tongue, deep in the ear), and where it radiates. Indicate whether it is constant or intermittent, and what triggers it (swallowing, talking, yawning, coughing, touching the throat). Rate the pain on a 0-10 scale on your worst days.
Worst-day example:
“On my worst days, I experience sudden, stabbing electric shock pain that starts deep in my left tonsil area and shoots into my left ear. This occurs every time I swallow and sometimes randomly at rest, lasting 10-30 seconds per episode. I have 10-15 episodes per day on bad days and rate the pain 9/10 at its worst. I cannot eat solid food on these days and avoid speaking to minimize triggers.”
What the examiner listens for:
The examiner needs to identify the nerve distribution of the pain (must be in CN IX territory - throat, posterior tongue, tonsil, ear via Jacobson's nerve), whether it is constant versus episodic, and what triggers or relieves it. They will document this for the DBQ pain fields (constant/excruciating, intermittent, dull).
Understatements to avoid:
Do not say 'my throat sometimes bothers me' or 'I have a little pain sometimes.' Instead say 'I have severe, recurring pain in my throat and ear that is triggered by swallowing and occurs multiple times daily, limiting what I can eat and how long I can speak.'
Swallowing Difficulty (Dysphagia)
How to describe:
Explain how often you have difficulty swallowing, what consistency of food/liquids is most difficult (solids, soft foods, liquids), whether you have choked or aspirated, and whether you have changed your diet because of it. Quantify - how many meals per week are affected, how much weight have you lost, how long does a meal take.
Worst-day example:
“On my worst days I cannot swallow solid food at all because every swallow triggers severe throat and ear pain. I have had to eat only soft pureed foods or liquids for days at a time. I have lost 12 pounds over the past year because eating is so painful I avoid it. I have choked on thin liquids on multiple occasions. I now cut all food into very small pieces and take small sips between bites even on good days.”
What the examiner listens for:
The examiner will document dysphagia severity for the DBQ swallowing field. They need specific functional details - not just 'yes I have trouble swallowing' but the grade of severity, dietary impact, aspiration risk, and weight consequences.
Understatements to avoid:
Do not simply say 'I have some trouble with certain foods.' Describe specifically what you cannot eat, how often this occurs, and whether it has caused aspiration, choking, or weight loss. These details directly influence the severity rating assigned.
Speech Difficulty (Dysarthria)
How to describe:
Describe whether your speech is slurred, nasal, breathy, or difficult to understand. Note whether speaking triggers pain. Explain how long you can speak before symptoms worsen, and whether this affects your work, phone calls, or social interactions.
Worst-day example:
“On my worst days, every word I speak triggers a stabbing pain in my throat. I have to limit conversations to a few sentences at a time. People frequently ask me to repeat myself because my voice becomes muffled and hoarse. I missed three work calls in the past month because I could not speak clearly without severe pain.”
What the examiner listens for:
The examiner documents difficulty speaking under the DBQ speech field. They will note whether dysarthria is constant or only with effort, and the degree to which it impacts communication and occupational function.
Understatements to avoid:
Do not omit speech symptoms because you can still technically speak. The functional impact - pain during speech, limited conversation duration, and impact on work - is what determines severity, not the ability to produce some sound.
Sensory Disturbances - Numbness and Paresthesias
How to describe:
Identify exactly where you feel numbness, tingling, pins-and-needles, or abnormal sensations: posterior tongue, tonsil region, soft palate, throat, outer ear canal, or jaw angle. Distinguish between areas that feel numb versus areas that feel painful or hypersensitive. Note whether these sensations are constant or intermittent.
Worst-day example:
“The back third of my tongue and the entire left side of my throat feel partially numb all the time, as if they were recently injected with dental anesthetic. Overlapping this numbness is a persistent burning sensation in my tonsil area that never fully goes away. On bad days the numbness extends up into my left ear canal.”
What the examiner listens for:
The examiner documents this under the paresthesias/dysesthesias and numbness DBQ fields. Constant versus intermittent sensory symptoms and the extent of affected area within CN IX distribution are key factors in differentiating mild from moderate impairment under the purely sensory rule.
Understatements to avoid:
Do not combine all sensory symptoms under 'numbness.' Separately identify: (1) areas of reduced or absent sensation, (2) areas of painful abnormal sensation (dysesthesia), and (3) areas of tingling or paresthesias. Each has different rating significance.
Salivation Changes
How to describe:
Report whether you produce too little saliva (dry mouth, difficulty initiating chewing, need to drink water with every meal) or excessive saliva (drooling, difficulty managing secretions). CN IX controls parotid gland salivation via the lesser petrosal nerve. Distinguish parotid gland dysfunction from any other cause.
Worst-day example:
“I experience significant dry mouth constantly because my left parotid gland does not produce saliva normally. I must sip water with every bite of food to be able to chew and swallow at all. I keep water on my nightstand because I wake up with my mouth painfully dry. My dentist has noted increased dental decay from chronic dry mouth over the past two years.”
What the examiner listens for:
The examiner documents salivation changes (increased or decreased) in the dedicated DBQ fields. These are specific CN IX manifestations that support the diagnosis and contribute to functional severity assessment.
Understatements to avoid:
Do not dismiss salivation changes as unrelated. Parotid gland dysfunction (dry mouth) is a direct and documentable consequence of CN IX neuritis and should be clearly reported with specific functional impacts like difficulty eating, dental complications, and nighttime symptoms.
Functional and Occupational Impact
How to describe:
Describe specifically how your CN IX neuritis limits what you can do at work, at home, and in social settings. Quantify lost workdays, tasks you can no longer perform, activities you have given up, and adaptations you have made. Address how the condition varies on different days.
Worst-day example:
“On my worst days, which occur approximately 10 days per month, I call in sick to work because I cannot speak on the telephone without triggering severe throat and ear pain, and I cannot eat a normal meal. I have given up attending restaurants with friends entirely. I spend those days surviving on protein shakes and avoiding conversation. Even on average days I have to eat alone, cut my food very small, and avoid meetings where extended speaking is required.”
What the examiner listens for:
The examiner documents functional impact in the dedicated DBQ field asking about impact of each condition on daily function and occupation. This section directly influences how the examiner characterizes the severity of incomplete paralysis and is one of the most important parts of the exam.
Understatements to avoid:
Do not say 'it affects my daily life' without specifics. Quantify: how many days per month are severely affected, which specific job tasks are limited or impossible, what recreational activities have been abandoned, and what accommodations you require.
Common Mistakes to Avoid
Describing only your average or 'good day' symptoms
VA rating is based on the full picture of the disability, including its worst manifestations. Underreporting severe episodes means the examiner documents a milder condition than actually exists.
Instead: Explicitly describe your worst days and how often they occur. M21-1 guidance supports reporting the full range of symptom severity. Say 'on my worst days, which happen X times per month, I experience...' followed by specific severe symptom descriptions.
Impact: Can cause a rating of 10% when 20-40% is warranted
Failing to connect all symptoms to CN IX distribution
The examiner must document symptoms within the glossopharyngeal nerve territory. Symptoms reported without location context may be attributed to other causes and not recorded under the CN IX DBQ fields.
Instead: Explicitly locate every symptom: 'Pain in the left side of my throat, behind the tonsil, and radiating into my left ear' rather than 'throat pain.' Know that CN IX innervates: posterior tongue, tonsil, pharynx, middle ear (Jacobson's nerve), and parotid gland.
Impact: Can prevent any rating or result in underrating
Not reporting organic changes separately from pain
The maximum neuritis rating (severe incomplete paralysis level) requires organic changes: loss of reflexes, muscle atrophy, sensory disturbances, AND constant pain per 38 CFR 4.123. If you do not report each of these components, the examiner cannot document them.
Instead: Separately and explicitly report: (1) absent or reduced gag reflex as observed by providers, (2) any documented muscle atrophy, (3) all types of sensory disturbances with locations, and (4) the constant versus episodic nature of your pain. Bring records showing these findings if they have been previously documented.
Impact: Determines whether rating reaches severe incomplete paralysis (40%) versus moderate (20%)
Omitting the impact of swallowing and speaking difficulties on work and daily life
The DBQ has a dedicated field for functional impact. If you describe symptoms without explaining how they prevent specific work tasks and daily activities, the examiner may rate the functional impairment as minimal.
Instead: Prepare a written list of specific work tasks and daily activities that your swallowing and speaking difficulties prevent or limit. Present this at the exam. The functional impact section of the DBQ is directly tied to the overall disability rating.
Impact: Can shift rating from 10% to 20-40%
Treating salivation changes, GI symptoms, and taste loss as minor or unrelated
These symptoms have dedicated DBQ checkboxes and directly support the CN IX neuritis diagnosis. Failing to report them means the examiner has an incomplete clinical picture and may assign a lower severity.
Instead: Explicitly report: dry mouth and its functional consequences, any nausea or GI symptoms related to the condition, and taste abnormalities on the posterior tongue. These are all medically recognized manifestations of CN IX pathology and are part of the rated disability.
Impact: Can result in underrating by one severity level
Not bringing prior medical records and diagnostic studies to the exam
The examiner reviews prior evidence including service treatment records, private records, imaging, and nerve conduction studies. Gaps in the record can result in the examiner having insufficient basis to document organic changes.
Instead: Bring copies of: any MRI or CT of the brain/skull base showing CN IX pathology, EMG or nerve conduction studies, prior neurology notes documenting your diagnosis, any records showing gag reflex findings, and records of dysphagia evaluations or modified diet orders. The DBQ requires documentation of imaging and other test results.
Impact: Affects all rating levels - insufficient evidence harms the overall claim

Your Rights During a C&P Exam
- You have the right to a thorough and adequate C&P examination. The examiner must address all claimed symptoms and provide findings sufficient for VA rating purposes.
- You have the right to request that your C&P examination be recorded in most states. Confirm this right with your VSO before the exam and bring a recording device if permitted.
- You have the right to bring a VSO representative, family member, or caregiver to the examination as a support person (they may not intervene in clinical testing but can be present).
- You have the right to submit additional lay statements, buddy statements, and private medical opinions as part of your evidence record at any time before a rating decision is issued.
- You have the right to request a copy of the completed DBQ through your VA records access tools or a records request. Review the DBQ for accuracy and completeness.
- You have the right to challenge an inadequate examination. If the DBQ fails to address all your symptoms, omits a nexus opinion, or contradicts the evidence of record, you may request a new examination through your VSO.
- You have the right to submit a private independent medical opinion (IMO) from a qualified neurologist to supplement or challenge the C&P findings.
- You are entitled to benefit of the doubt under 38 CFR 3.102. When the evidence is in approximate balance, the benefit of the doubt must be given to the veteran.
- You have the right to be informed of all rating criteria under 38 CFR 4.124a that apply to your condition so you can accurately communicate the full extent of your disability.
- You have the right to file a Notice of Disagreement (NOD) if you disagree with the rating decision, and to request a Higher Level Review, Supplemental Claim, or Board of Veterans Appeals hearing.
Related Conditions
- Ninth (Glossopharyngeal) Cranial Nerve, Neuralgia DC 8407 is the companion code for neuralgia of CN IX, rated at a maximum of moderate incomplete paralysis. Neuritis (DC 8309) can be upgraded to maximum severe incomplete paralysis when organic changes are present. Ensure the correct diagnostic code is applied based on clinical findings.
- Tenth (Vagus) Cranial Nerve Conditions CN X runs adjacent to CN IX and is often co involved in lesions at the jugular foramen or skull base. CN X involvement causes hoarseness, aspiration, and autonomic dysfunction. Separate ratings may apply if CN X is independently affected.
- Seventh (Facial) Cranial Nerve Conditions CN VII may be co involved in posterior fossa or parotid region pathology related to CN IX conditions. Facial weakness or taste changes on the anterior two thirds of the tongue are CN VII findings and may be separately ratable.
- Eighth (Vestibulocochlear) Cranial Nerve Conditions CN VIII disorders may co occur with CN IX pathology in cerebellopontine angle tumors or posterior fossa lesions. Hearing loss, tinnitus, and vertigo are CN VIII manifestations and may warrant separate evaluation.
- Twelfth (Hypoglossal) Cranial Nerve Conditions CN XII controls tongue movement. If co involved, it produces tongue weakness and atrophy, compounding swallowing and speech difficulties attributed to CN IX. Separate rating may apply under DC 8312.
- Dysphagia (Swallowing Disorder) Severe dysphagia secondary to CN IX neuritis may produce independently ratable consequences including aspiration pneumonia, malnutrition, or esophageal dysfunction. Document all downstream health consequences of your swallowing disorder.
