D7899 — Unspecified TMD therapy, by report
D7899 is the by-report code for jaw-joint treatment that none of the specific TMD codes describes.
This code belongs to a set of 22 covering temporomandibular joint treatment. The clinical detail lives in the temporomandibular joint treatment guide; the code-level detail is here.
What the code requires, what it costs, how it is paid, and how to tell it from its neighbours — each in its own section below.
The specifics of D7899
Documentation — by report. A written narrative describing what was done and why no specific code applied has to accompany the claim. Submitted without one it is not assessed, it is simply returned.
Told apart from the codes it is confused with
D7881 — Occlusal orthotic device adjustment (TMJ/TMD): It is the specific code to use in preference to a by-report one.
D7880 — Occlusal orthotic device, by report (TMJ/TMD): It is the occlusal orthotic, the bite appliance made to reposition or unload the joint, reported by narrative.
D7877 — Arthroscopy: debridement (TMJ): It is the specific code to use in preference to a by-report one.
D7876 — Arthroscopy: discectomy (TMJ): It is the specific code to use in preference to a by-report one.
D7899 sits in a group of 22 codes in total; the remainder are linked at the foot of this page. The safest question to ask is not "what does this cost" but "which code is going on the claim". The first answer changes; the second decides the first.

These codes describe the same broad procedure and differ in one respect each. Each has its own page with its own fee range and coverage notes.
