D7994 — Surgical placement: zygomatic implant
D7994 places a zygomatic implant, anchored in the cheekbone where the upper jaw has too little bone left.
There are 18 codes for other oral surgical procedures and they are not interchangeable. This page covers this one; the other oral surgical procedures guide covers the treatment they all share.
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.
D7994 in detail
Bone — the cheekbone and its arch. The zygoma forms the prominence of the cheek and the outer wall of the eye socket. Displacement shows up as a flattened cheek, a step in the orbital rim, numbness of the cheek and upper lip, and sometimes double vision — which is why these are assessed for the eye as much as for the bone.
Told apart from the codes it is confused with
D7993 — Surgical placement of craniofacial implant — extra-oral: It places a craniofacial implant outside the mouth, the anchor a facial prosthesis then clips onto.
D7990 — Emergency tracheotomy: It is the emergency tracheotomy performed to secure an airway.
D7983 — Closure of salivary fistula: It closes a fistula that is leaking saliva through the skin or into the mouth.
D7982 — Sialodochoplasty (salivary duct repair): It repairs or reroutes a damaged salivary duct.
D7994 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.

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.
Questions about D7994
What procedure is D7994?
Surgical placement: zygomatic implant, reported under a single oral and maxillofacial surgery code.
What should I expect to pay for D7994?
Expect $2,500–$7,000. Ask for the number in writing, because the code carries no fee of its own and every practice sets its own.
Is D7994 a covered benefit?
Typically, yes — major oral surgery benefits, variable. What varies between plans is the frequency limit rather than whether the procedure is covered at all.
What is the difference between D7994 and D7993?
D7993 is surgical placement of craniofacial implant, extra-oral: it places a craniofacial implant outside the mouth, the anchor a facial prosthesis then clips onto. They share a section of the code set and very little else, so the comparison worth making is on what each involves rather than on which is cheaper.
