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

What 12042 covers

This code covers intermediate repair of wounds on the neck, hands, feet, or external genitalia when the qualifying length is 2.6–7.5 cm. It describes layered closure involving deeper tissue as well as skin, or single-layer closure of a heavily contaminated wound that requires extensive cleaning or removal of particulate matter. Emergency clinicians, surgeons, dermatologists, and other clinicians performing wound repair may report it in an office, emergency department, or outpatient facility.

Select the code using the wound’s documented length, anatomic site, and repair method. Record the site, measured length, tissue layers closed, and, for a contaminated wound closed in one layer, the extensive cleaning performed. Related postoperative visits during the 10-day global period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.
