Answer: For this claim, you’ll need a pair of codes. On the claim, report: More about +61517: This is an exclusive add-on code. According to CPT®, only two codes are approved for use with +61517: 61510 and 61518 (Craniectomy for excision of brain tumor, infratentorial or posterior fossa; except meningioma, cerebellopontine angle tumor, or midline tumor at base of skull). If you see it used with another code, red flags should rise up.
