The VA rates temporomandibular joint disorder (TMJ or TMD) under diagnostic code 9905, with ratings of 10%, 20%, 30%, 40%, or 50%. The rating depends on two measurements: how far you can open your jaw between your front teeth (inter-incisal range, measured in millimeters) and whether you need a modified diet, such as soft foods or a liquid diet, to eat because of jaw restriction. A veteran who can open their mouth only 15mm and needs a soft-food diet, for example, could qualify for a 40% rating rather than the 30% rating based on motion alone.
TMJ is one of the more overlooked VA claims. Many veterans develop it from jaw injuries, dental trauma, or grinding and clenching linked to PTSD, and never realize it is separately ratable and often connectable to an already service-connected condition. This guide breaks down the 2026 rating criteria, how the C&P exam works, and how to file a claim or get help with your benefits.
What Is TMJ and How Does the VA Rate It
Temporomandibular joint disorder affects the hinge connecting your jawbone to your skull. Symptoms include jaw pain, clicking or popping, limited ability to open your mouth, headaches, and difficulty chewing. Veterans develop TMJ from direct trauma (blast injuries, vehicle accidents, combat impacts), dental work, or chronic teeth grinding and jaw clenching often tied to stress, PTSD, or sleep disorders.
The VA schedule for rating this condition falls under 38 CFR 4.150, diagnostic code 9905, titled "Temporomandibular disorder (TMD)." Unlike many musculoskeletal conditions that combine pain and function scores, DC 9905 is rated almost entirely on two objective measurements taken during a Compensation and Pension (C&P) exam:
- Inter-incisal range of motion: the distance in millimeters between your upper and lower front teeth when you open your mouth as wide as possible
- Lateral excursion: how far your jaw can move side to side
A normal, unassisted jaw opening is generally considered 35mm to 50mm. Anything below that range can support a rating, and the rating increases as the opening shrinks or as dietary restriction becomes necessary.
VA TMJ Rating Chart 2026 (Diagnostic Code 9905)
The table below reflects the current criteria under DC 9905. Ratings for limited inter-incisal movement are not combined with ratings for limited lateral excursion. The VA uses whichever measurement produces the higher, most accurate rating for your case.
| Inter-Incisal Opening | No Dietary Restriction | Soft/Semi-Solid Diet | Liquid or Pureed Diet |
|---|
| 30 to 34mm | 10% | 20% | 30% |
| 21 to 29mm | 20% | 30% | 40% |
| 11 to 20mm | 30% | 40% | 40% |
| 0 to 10mm | 40% | 50% | 50% |
Lateral excursion: A side-to-side jaw movement limited to 0 to 4mm is rated at 10%. This rating is not combined with the inter-incisal opening rating; the VA applies whichever standalone measurement gives you the higher percentage.
To be rated at the higher, diet-restricted tiers, the modified diet (blended, chopped, ground, or mashed food, or a liquid/pureed diet) generally needs to be documented or verified by a physician, not just self-reported during the exam.
There is no single "TMJ disability rating" that applies to everyone. Your percentage depends entirely on what the examiner measures on the day of your C&P exam, which is why documenting bad days, flare-ups, and eating limitations before your exam matters.
How Diet Restriction Raises Your Rating
This is the part many veterans miss. Two veterans with the exact same jaw-opening measurement can receive different ratings if one has documented dietary limitation and the other doesn't. If your jaw pain or restricted opening forces you to eat only soft, blended, or liquid foods, tell your doctor and get it noted in your medical records before your C&P exam. A rating decision based only on millimeters of motion, without factoring in real-world eating limitations, may understate how disabling your TMJ actually is.
How to File a VA Claim for TMJ
Step 1: Establish a current diagnosis. You need a formal TMJ or TMD diagnosis from a dentist, oral surgeon, or physician. This can come from VA healthcare, a private dentist, or an in-service dental record.
Step 2: Connect it to your service. You'll need one of the following:
- A direct link: an in-service jaw injury, blast exposure, dental trauma, or documented onset of jaw symptoms during service
- A secondary connection: TMJ caused or worsened by an already service-connected condition, most commonly PTSD (through chronic clenching or bruxism), a service-connected neck or facial injury, or sleep apnea treatment devices that strain the jaw
Step 3: File VA Form 21-526EZ. Submit through VA.gov, by mail, in person at a VA regional office, or with help from an accredited Veterans Service Officer (VSO) or attorney. Filing an Intent to File (VA Form 21-0966) first can lock in an earlier effective date while you gather evidence.
Step 4: Attend the C&P exam. The examiner will measure your maximum jaw opening and lateral excursion with a ruler or calipers, ask about pain, clicking, headaches, and chewing difficulty, and review whether you need a modified diet. Bring notes on flare-ups and specific foods you can no longer eat.
Step 5: Wait for the rating decision. VA claims processing typically takes several months. You can track claim status through VA.gov or the VA mobile app.
Getting a Higher Rating: What Helps Your Claim
- Document flare-ups. Jaw function fluctuates. If your worst days are far more restrictive than your best days, note this in a personal statement so the examiner and rater understand your typical functioning, not just a single snapshot.
- Get dietary restrictions on record. Ask your treating dentist or doctor to formally note if you require soft, blended, or liquid foods due to jaw pain or limited opening.
- List secondary symptoms. Chronic headaches, ear pain, and neck tension often accompany TMJ and may support additional secondary claims.
- Connect it to PTSD if applicable. Bruxism (teeth grinding) and jaw clenching are well-documented secondary effects of PTSD and anxiety disorders. A nexus letter from a treating provider linking your TMJ to a service-connected mental health condition can be the difference between a denial and an approval.
TMJ and VA Compensation: What a Rating Is Worth
VA disability ratings combine with any other service-connected conditions you have to determine your total combined rating, which sets your monthly payment. As of December 2025 (2026 payment rates), a veteran with no dependents receives approximately:
| Combined Rating | Monthly Payment (Veteran Alone) |
|---|
| 10% | $180.42 |
| 20% | $356.66 |
| 30% | $552.47 |
| 40% | $795.84 |
| 50% | $1,132.90 |
These figures are for a single veteran with no dependents; ratings of 30% and above increase if you have a spouse, children, or dependent parents. TMJ is rarely a veteran's only service-connected condition, so your TMJ rating typically combines with other ratings using VA math rather than simple addition, which can change your total combined percentage and monthly payment.
Common Reasons TMJ Claims Get Denied or Underrated
- No current diagnosis on file. A history of jaw pain without a formal TMJ/TMD diagnosis from a dentist or physician is not enough.
- Missing nexus evidence. Especially for secondary claims tied to PTSD or bruxism, the VA needs a medical opinion explicitly linking the conditions, not just a shared history.
- Undocumented dietary restriction. If you tell the examiner you eat only soft foods but there's nothing in your medical records supporting it, the rater may not credit the higher tier.
- Exam measured on a good day. If your C&P exam happens to fall during a period of less restriction, your rating may not reflect your typical functioning. A buddy statement or personal statement describing your average day can help.
Frequently Asked Questions
What is the VA disability rating for TMJ?
TMJ (temporomandibular joint disorder) is rated under diagnostic code 9905 at 10%, 20%, 30%, 40%, or 50%, depending on how far you can open your jaw in millimeters and whether you require a modified diet due to jaw restriction.
Can TMJ be a secondary condition to PTSD?
Yes. Chronic jaw clenching and teeth grinding (bruxism) linked to PTSD, anxiety, or stress are recognized pathways for a secondary service connection. You'll need a medical opinion connecting your TMJ diagnosis to your service-connected mental health condition.
What is diagnostic code 9905?
Diagnostic code 9905, found in 38 CFR 4.150, is the VA's rating schedule for temporomandibular disorder. It rates disability based on inter-incisal jaw opening (in millimeters) and lateral excursion, with higher ratings for smaller openings and documented dietary restrictions.
Do I need a special diet to get a higher TMJ rating?
Not necessarily, but documented dietary restriction (soft, blended, or liquid foods) can raise your rating within the same jaw-opening range. Ask your dentist or doctor to note any diet limitations caused by your jaw condition in your medical records.
How long does a VA TMJ claim take to process?
VA disability claims generally take several months from filing to decision, though timelines vary based on claim complexity and whether additional evidence or exams are needed. Filing a complete claim with medical records and a nexus letter (for secondary claims) upfront tends to move faster than claims requiring follow-up development.
Can TMJ combine with other VA disability ratings?
Yes. Your TMJ rating combines with all other service-connected disabilities using VA's combined ratings formula, not simple addition, to produce your total disability percentage, which determines your monthly compensation.
