Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 21030 covers

This service removes a benign tumor or cyst arising in the maxilla or zygoma by enucleating the lesion and curetting its bony site. Oral and maxillofacial surgeons commonly perform it for an intraosseous lesion identified on dental or facial imaging, with the specimen sent for pathologic examination. The approach and setting depend on the lesion and the patient; the defining work is enucleation and curettage, rather than resection of a malignant tumor or removal of a superficial facial mass.

Report the code when the operative record identifies a benign maxillary or zygomatic tumor or cyst and documents enucleation with curettage. A 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. For bilateral reporting with modifier 50, CMS pays at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
