Use PA-Specific Modifier to Report Their Services

Question: A physician assistant (PA) assisted one of our surgeons during a surgery. The provider is billing 58571 for their services. Would I bill the PA as 58571-80 or 58571-AS? What’s the best modifier to use to report their work?

Answer: For this situation, you would report 58571 (Laparoscopy, surgical, with total hysterectomy, for uterus 250 g or less; with removal of tube(s) and/or ovary(s)) and then choose a modifier.

Modifier 80 (Assistant Surgeon) would be appropriate for reporting the assistance of another MD or surgeon. However, in this situation, with a midlevel provider, you’d look to modifier AS (Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery). While the Centers for Medicare & Medicaid Services (CMS) accepts modifier AS for Medicare beneficiaries, you’d need to check with the respective commercial carrier’s guidelines to make sure you’re submitting claims per their preferences for reimbursement.
