V.iii.14.2.b. Special Considerations in Evaluations for TMD | | Temporomandibular disorder (TMD) (which may also be called temporomandibular joint dysfunction (“TMJD” or more colloquially TMJ”)) is evaluated under 38 CFR 4.150, DC 9905. Evaluation levels are based on- limitation of inter-incisal range of motion (with or without dietary restrictions), or
- range of lateral excursion.
When assigning an evaluation there are a number of considerations. For Department of Veterans Affairs purposes, normal maximum unassisted range of inter-incisal motion is 35 to 50mm. - A 10-percent evaluation can be assigned for no more than 34 mm of inter-incisal motion.
- Under the prior version of the DC (effective prior to September 10, 2017), a 10-percent evaluation was available for motion up to 40 mm.
For each range of maximum assisted inter-incisal motion, the appropriate evaluation to assign will depend on whether or not the condition necessitates dietary restriction to mechanically-altered foods. - The regulation provides in Note (3) that mechanically altered foods are foods altered by blending, chopping, grinding, or mashing to make them easier to chew and swallow. Mechanical alteration can be to one of four levels or gradations: full liquid, puree, soft, and semi-solid.
- The note refers to dietary restrictions in which mechanically altered foods are required as texture modified diets.
- Dietary restrictions involving any textured modified diet (any grade of mechanically altered food) must be recorded or verified by a physician.
- A contention or testimony by an individual that he or she is using a texture modified diet or requires one due to the SC condition is not sufficient to establish that the condition necessitates a texture modified diet with restriction to mechanically altered foods.
- Endorsement of the need for the dietary restriction to mechanically altered foods by a competent medical professional is required. An examination report may satisfactorily record or verify that the SC condition necessitates the dietary restriction to mechanically altered food.
With respect to inter-incisal range of motion, the DC requires ranges be “unassisted.” This means active range of motion. In assigning an evaluation for TMD or any other dental disability on the basis of limited motion of temporomandibular articulation under 38 CFR 4.150, DC 9905, do not assign separate evaluations for limited inter-incisal motion or painful motion involving each side of the jaw. Doing so is pyramiding. Only one evaluation may be assigned. If both sides of the jaw are affected, use the limitation of motion on the side that affords the highest evaluation. Example: Maximum unassisted inter-incisal motion is limited to 34 mm on the right and 25 mm on the left. There is no dietary restriction to mechanically altered foods. There is credible evidence of actually painful motion of both sides of the jaw. Assign a single 20-percent evaluation under 38 CFR 4.150, DC 9905. Do not assign separate 10-and 20-percent evaluations.Do not combine ratings for limited inter-incisal motion with a rating based on limitation of lateral excursion of the jaw.
