About 61316: Subcutaneous cranial bone flap placement
Reports placement of a cranial bone flap beneath the skin during cranial surgery so it can be preserved for possible later reconstruction.
During cranial surgery, the neurosurgeon places a removed bone flap in a subcutaneous pocket, commonly in the abdomen, to preserve it for possible later cranioplasty. This is a separate storage step during the operation, not the later reconstruction of the skull. It may accompany a decompressive craniectomy when the flap cannot be replaced immediately.
Report 61316 only with a primary procedure. The operative note should identify the cranial bone flap, document its subcutaneous placement, and support that this step occurred during the same operative session as the primary cranial surgery. Do not report it for a flap that was removed but not placed subcutaneously, or for later replacement of a stored flap. CMS pays this add-on within the primary procedure's global period; it is not a standalone service.

61316 billing questions

No. It is an add-on code and must be billed with a primary procedure from the same operative session.
How is bone-flap storage different from cranioplasty?
61316 reports placing the removed flap beneath the skin for possible later use. Cranioplasty codes describe reconstruction or replacement of the skull defect, generally at a later operation.
What documentation supports 61316?
The operative report should identify the removed cranial flap and describe its placement in a subcutaneous pocket during the primary surgery.
How many units are reported when one flap is stored?
Report the service for the documented placement of the cranial bone flap; the operative note should make clear what was placed and where.
How does the global period affect payment?
CMS pays 61316 within the global period of the primary procedure with which it is billed.
