This reference uses VA rating codes. For a code from a medical record, check ICD-10-CM and the service date. A clinical code alone does not establish a VA rating or a matching VA diagnostic code.
Temporomandibular disorder (TMD)
Dental and oral · 38 CFR § 4.150
Diagnostic Code 9905 is the VASRD entry for Temporomandibular disorder (TMD). VA applies the controlling criteria, shared formulas, and special instructions shown in 38 CFR Part 4. VMC presents this material for education and reference; it does not determine a Veteran's diagnosis, service connection, or evaluation.

Special rating instructions
- Interincisal range:
- 0 to 10 millimeters (mm) of maximum unassisted vertical opening.
- 11 to 20 mm of maximum unassisted vertical opening.
- 21 to 29 mm of maximum unassisted vertical opening.
- 30 to 34 mm of maximum unassisted vertical opening.
- Lateral excursion range of motion:
Regulatory notes
- Note (1): Ratings for limited interincisal movement shall not be combined with ratings for limited lateral excursion
- Note (2): For VA compensation purposes, the normal maximum unassisted range of vertical jaw opening is from 35 to 50 mm
- Note (3): For VA compensation purposes, mechanically altered foods are defined as altered by blending, chopping, grinding or mashing so that they are easy to chew and swallow. There are four levels of mechanically altered foods: full liquid, puree, soft, and semisolid foods. To warrant elevation based on mechanically altered foods, the use of texture-modified diets must be recorded or verified by a physician

Evidence information
When reviewing the criteria, useful evidence categories can include diagnosis and treatment records, objective testing identified by the schedule, documented frequency/duration/severity when the criteria use those concepts, and functional effects described in medical or lay evidence. The relevant evidence depends on the actual claim and medical facts.
VMC does not diagnose conditions, guarantee a percentage, or advise anyone to exaggerate symptoms.
