Temporomandibular disorder — jaw pain, clicking and limited opening — rated by measured jaw opening and dietary restriction. This guide quotes the actual rating criteria from 38 CFR Part 4 for diagnostic code 9905, explains what the C&P examiner measures, covers the presumptive and secondary routes to service connection, and lists the reasons these claims come back denied — and how each gets fixed.
How the VA rates tmj in 2026 — the exact criteria
These are the criteria a VA rater applies, quoted from the rating schedule (§ 4.150). Your rating is the highest level whose wording your evidence meets — and evidence that never uses these words tends to be rated at the bottom.
DC 9905 — Temporomandibular disorder (TMD)
| Rating | Criteria (38 CFR Part 4 wording) |
|---|---|
| 50% | 0 to 10 mm of maximum unassisted vertical opening with dietary restrictions to all mechanically altered foods |
| 40% | 0 to 10 mm without dietary restriction; or 11 to 20 mm with dietary restrictions to all mechanically altered foods; or 21 to 29 mm with dietary restrictions to full liquid and pureed foods |
| 30% | 11 to 20 mm without dietary restriction; or 21 to 29 mm with soft and semi-solid foods; or 30 to 34 mm with full liquid and pureed foods |
| 20% | 21 to 29 mm without dietary restriction; or 30 to 34 mm with soft and semi-solid foods |
| 10% | 30 to 34 mm of maximum unassisted vertical opening without dietary restriction; or lateral excursion range of motion 0 to 4 mm |
Normal maximum unassisted vertical jaw opening is 35 to 50 mm. Ratings for limited interincisal movement are not combined with ratings for limited lateral excursion. A texture-modified diet must be recorded or verified by a physician to count.
Honest ceiling: 50% when limited opening forces an altered diet.
What the C&P examiner measures
Maximum unassisted vertical opening and lateral excursion in millimeters, clicking, pain, and any physician-verified dietary restriction to soft, pureed or liquid foods. Bring dental records documenting bruxism, wear and the joint findings.
The questions that get at the rating criteria — answer them for yourself before the exam:
- Dentist ever tell you you're grinding your teeth down?
- Does your jaw click, pop, or lock up?
Service connection: presumptive, direct, or secondary
No presumption. Direct connection from an in-service jaw injury or dental treatment, or secondary to PTSD/anxiety through bruxism (clenching and grinding).
Every service-connection claim has three legs: a current diagnosis (the C&P exam can supply it), an in-service event, injury, exposure or an already-connected condition, and a link between the two — which the VA's own examiner addresses at the exam for direct and secondary claims, and which the law supplies for presumptive ones. You do not need a private opinion to file; you need one only if the VA denies for lack of nexus, and a supplemental claim within one year keeps your effective date.
Secondary conditions veterans miss
This condition is more often the secondary in a chain than the anchor — see the secondary-claims guides for the recognized pathways.
What the medical literature says
Manfredini D., Lobbezoo F., Journal of Orofacial Pain (2009) — role of psychosocial factors in the etiology of bruxism
Stress and anxiety are established contributors to bruxism, the primary driver of TMJ pathology. Why it matters: TMJ secondary to service-connected MH via bruxism.
Why tmj claims get denied — and the fix
- Jaw opening measured once on a good day; dietary restriction not verified by a physician.
A denial is a grade on the evidence packet, not a verdict on you. Filed as a supplemental claim within one year, the fix keeps your original effective date.
Filing it right the first time
- Intent to File first. It locks your effective date for a year — back pay runs from that day, not from the day the package is ready.
- File everything at once. Every condition with a real symptom and a plausible route — direct, presumptive, secondary, increase — goes in one claim. The VA's duty to assist schedules the exam and pulls your records; a condition held back "for more evidence" only starts its clock later.
- Your statement in the criteria's words. A Statement in Support of Claim (VA Form 21-4138) that describes your worst days and your typical days using the language in the table above is the evidence the rater reads first.
- Your records. VA records through Blue Button, decision letters and code sheet from VA.gov, and private records from each doctor's office or patient portal — or a signed 21-4142 so the VA pulls them.
- Prepare for the exam. Know what the examiner measures (above) and answer honestly, including the bad days.

What is the VA rating for tmj?
TMJ is rated under diagnostic code 9905 (§ 4.150) at 10%, 20%, 30%, 40%, 50%. The percentage depends on which criteria in the rating schedule your evidence meets — the full table is on this page.
What is the highest VA rating for tmj?
The highest schedular rating available is 50%. Typical grants land around 10%, but every case is decided on its own evidence.
Is tmj a presumptive condition?
No presumption. Direct connection from an in-service jaw injury or dental treatment, or secondary to PTSD/anxiety through bruxism (clenching and grinding).
Do I need a nexus letter for tmj?
Not to file. The VA's duty to assist schedules a C&P exam where its own examiner addresses the connection, and presumptive conditions need no opinion at all. A private opinion becomes worth buying only if the VA denies for lack of nexus — a supplemental claim within one year keeps your original effective date.
