What 62148 covers
During cranioplasty or other skull reconstruction, a neurosurgeon repositions a cranial bone flap as part of restoring the skull’s contour and coverage. This work may occur when a prior craniectomy left a defect requiring reconstruction. The code captures the additional flap-repositioning work, not a separate operation to remove a flap or place a prosthetic plate.
Report 62148 only with its qualifying primary skull-repair procedure; it is not a standalone service. The operative note should identify the bone flap and describe its repositioning in the reconstruction. CMS treats this as an add-on paid within the primary procedure’s global period. Distinguish this work from simply replacing a bone flap or prosthetic plate, and select the primary procedure based on the documented skull repair and reconstruction performed.
