D5864 — Overdenture — partial maxillary
D5864 is the partial upper version, covering some teeth and replacing others.
One of four overdenture on natural teeth codes. If you are trying to understand the treatment, start with the overdenture on natural teeth guide; if you are trying to understand this line on your estimate, you are in the right place.
Everything below is specific to this code: what it pins down, what it is worth, how a payer handles it, and which codes it is not.
The specifics of D5864
Arch — upper. The palate provides broad support for anything removable, but the sinuses sit directly above the back teeth, which constrains surgical work.
How D5864 differs from its neighbours
D5863 — Overdenture — complete, on natural teeth (upper): It is a complete upper denture designed to sit over retained natural teeth rather than on bare gum.
D5865 — Overdenture — complete, on natural teeth (lower): It is the lower-jaw version.
D5866 — Overdenture — partial, mandibular: It is the lower-jaw version.
Those three codes and D5864 are the whole group — nothing else describes this procedure. Reviewers compare the narrative against the code rather than the other way round, so the question worth asking is what the notes will say.
