About 11900: Intralesional injection of up to seven lesions
Reports medication injected directly into one to seven skin lesions, such as keloids or hypertrophic scars, during a single treatment session.
A clinician injects medication directly into skin lesions, commonly using an intralesional corticosteroid for keloids, hypertrophic scars, or selected inflammatory lesions. Dermatologists and other clinicians who treat these conditions perform the service in office settings and, less often, in facility settings. The code is selected by the number of lesions treated, not the number of needle passes or the medication volume; it covers treatment of one through seven lesions. More than seven lesions are reported with 11901.
Document the treated lesions and their number, the medication and dose, and the clinical reason for injection. The medication may be reported separately when applicable and supported by documentation. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment is restricted, and co-surgeon and team-surgery reporting are not permitted.

11900 billing questions
How many lesions qualify for 11900?
Report 11900 for treatment of one through seven lesions in the session. Use 11901 when more than seven lesions are treated.
Do separate injections into one lesion count as multiple lesions?
No. Select the code by the number of distinct lesions treated, not the number of needle passes or injection sites within a lesion.
Can the injected medication be billed separately?
The medication may be reported separately when applicable. Document the drug and dose, and follow the applicable drug-code requirements.
Is modifier 50 appropriate when lesions are on both sides of the body?
No. CMS identifies bilateral adjustment as inappropriate for 11900; report the service based on the number of lesions treated.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure. CMS applies the standard multiple-procedure reduction when other procedures are performed in the same session.
Can an assistant or co-surgeon be reported?
CMS does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
