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

What 11901 covers

Code 11901 represents the clinician’s work injecting medication directly into more than seven discrete skin lesions in one treatment session. Dermatologists commonly use intralesional corticosteroid injections for multiple keloids or hypertrophic scars. The clinician identifies the target lesions and places the medication within them, rather than injecting a subcutaneous filling material for volume correction.

Select 11901 by the number of lesions actually injected: more than seven qualifies, while 11900 covers up to seven. Document the lesion count and locations, indication, agent and amount, and injection service. This code has a 0-day global period, so same-day preoperative and postoperative care is included. When another procedure is performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment is statutorily restricted, and co-surgeon and team-surgery billing are not permitted.
