About 11901: Intralesional injection of multiple skin lesions
Report this service when a clinician injects intralesional medication into more than seven discrete skin lesions during one treatment session.
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.

11901 billing questions
When should 11901 be chosen instead of 11900?
Count the discrete lesions actually injected during the treatment session. Use 11901 for more than seven lesions; 11900 covers up to seven.
Is the code reported once per lesion or once per session?
Choose the code level based on the total number of lesions injected in the session. Do not report one unit for each lesion or needle pass.
Can the medication be billed separately?
The procedure code represents the intralesional injection service, not the medication product. Report a separately identifiable drug product under the applicable drug coding rules when eligible.
Can modifier 50 be used for lesions on both sides?
No. Bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.
What same-day care is included?
The code has a 0-day global period, so same-day preoperative and postoperative care is included. A separately identifiable evaluation may be reported when its documentation supports a distinct E/M service.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
