D7999 — Unspecified Oral & maxillofacial surgery Procedure (By Report)
D7999 is the by-report code used when an oral and maxillofacial surgery procedure does not match any specific code in the set.
D7999 is the by-report code that closes the oral and maxillofacial surgery section of the code set. It is reported when unusual oral surgical work was genuinely performed but no specific code in that section describes it.
It carries no defined procedure and no defined fee, only an obligation: the claim must be accompanied by a written narrative. What that narrative has to establish is specific to this section, and it is set out below.
What actually gets billed under D7999
Surgical by-report claims are the most varied of all. They cover unusual approaches to impacted or ankylosed teeth, management of intraoperative complications, surgery on patients whose medical condition dictated a different technique, combined procedures performed in one operation, and reconstruction that no single code describes. Surgery performed under hospital conditions frequently ends up here.
What a reviewer of an oral and maxillofacial surgery claim is looking for
Surgical reviewers read the operative note, so the operative note is the narrative. It should record the approach, the anatomy encountered, any complication and its management, the operating time, and the surgeon's reasoning. This is the section in which a well-written note most reliably produces payment.
If this code is on your treatment plan
Three questions cover it: what is actually planned, what it will cost in writing, and what your insurer says in advance. The third matters most here, because a code with no fee behind it cannot be estimated from a fee schedule. Seeing this code is not a reason for suspicion; it is a reason to get the answers on paper.
Questions about D7999
What does D7999 mean on my dental bill?
It is the by-report code for unusual oral surgical work that no specific oral and maxillofacial surgery code describes. It has no fixed fee, so the narrative filed with the claim is what explains what was done.
What kind of oral and maxillofacial surgery work ends up under this code?
Surgical by-report claims are the most varied of all.
Will my plan pay a claim submitted under D7999?
It depends on the documentation rather than on the code. Surgical reviewers read the operative note, so the operative note is the narrative. It should record the approach, the anatomy encountered, any complication and its management, the operating time, and the surgeon's reasoning.
Is there a way to know the cost of D7999 in advance?
Only by pre-treatment estimate. Ask the practice to submit the narrative to your insurer before treatment; the answer comes back as a number rather than a range.
Also known as: by report, unspecified procedure, narrative required, pre-treatment estimate.
