D7921 — Collection and application of autologous blood concentrate product
D7921 spins the patient's own blood and applies the concentrate to the surgical site to speed healing.
This is one of 18 closely related other oral surgical procedures codes. The treatment is explained in full in the other oral surgical procedures guide — this page is about what makes this particular code different.
This page explains what that code number commits the office to, what it usually costs, how plans treat it, and — the part that causes most of the confusion — how it differs from the codes sitting immediately either side of it.
How D7921 differs from its neighbours
D7980 — Surgical sialolithotomy (salivary stone removal): It removes a stone blocking a salivary gland or its duct.
D7981 — Excision of salivary gland, by report: It is the by-report code used when nothing more specific fits.
D7982 — Sialodochoplasty (salivary duct repair): It repairs or reroutes a damaged salivary duct.
D7983 — Closure of salivary fistula: It closes a fistula that is leaking saliva through the skin or into the mouth.
D7921 sits in a group of 18 codes in total; the remainder are linked at the foot of this page. The practical point: confirm which of these is going on the claim before treatment, not after. Corrections after submission mean a resubmission, a delay, and occasionally a fee you did not expect.
Every code in this group
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.
