D2999 — Unspecified Restorative Procedure (By Report)
D2999 is the by-report code used when a restorative procedure does not match any specific code in the set, and must be described in a written narrative.
D2999 is the by-report code that closes the restorative section of the code set. It is reported when unusual restorative work was genuinely performed but no specific code in that section describes it.
Nothing about the procedure is built into the code, so nothing about it can be assumed. The narrative filed with the claim is the whole of the description, and the standard it is held to is particular to this part of the code set.
What actually gets billed under D2999
Restorative by-report claims are usually about restorations that cross the boundaries of the coded ones: a restoration spanning surfaces in a combination no code describes, repair of a specific defect in an existing crown that the repair codes do not fit, splinting several teeth together with bonded composite, or a newer material with no code of its own. Removal of a fractured post or the rebuilding of a tooth in stages also lands here from time to time.
What a reviewer of a restorative claim is looking for
Restorative reviewers assess these claims against the nearest coded restoration and want to know what made it different. Pre-operative and post-operative radiographs carry more weight in this section than in any other, because the extent of the damage is visible in them. Tooth number, surfaces involved and the material used must all be stated explicitly.
If this code is on your treatment plan
Find out what the practice intends to do, what it charges for it, and what your plan will allow — in that order, and before treatment. With no defined fee and no defined procedure, an estimate submitted in advance is the only way the number becomes knowable. That is the practical point, not any doubt about the code.
Questions about D2999
What does D2999 mean on my dental bill?
It is the by-report code for unusual restorative work that no specific restorative code describes. It has no fixed fee, so the narrative filed with the claim is what explains what was done.
What kind of restorative work ends up under this code?
Restorative by-report claims are usually about restorations that cross the boundaries of the coded ones: a restoration spanning surfaces in a combination no code describes, repair of a specific defect in an existing crown that the repair codes do not fit, splinting several teeth together with bonded composite, or a newer material with no code of its own.
Will my plan pay a claim submitted under D2999?
It depends on the documentation rather than on the code. Restorative reviewers assess these claims against the nearest coded restoration and want to know what made it different.
Is there a way to know the cost of D2999 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.
