What 11951 covers

This service is injection of filling material into subcutaneous tissue to improve a soft-tissue contour defect. Examples of materials include collagen-based fillers. Dermatologists and plastic surgeons may perform the procedure in a clinic or hospital setting, depending on the patient and treatment circumstances. Medicare payment is restricted to specific circumstances, so the clinical reason for treatment matters.

Select this code when the documented quantity injected falls from 1.1 through 5.0 cc; document the material, treatment site, amount, and reason for correction. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

11951 billing questions

How is this code distinguished from 11950 or 11952?

Choose by the volume of filling material injected: this code covers 1.1–5.0 cc, 11950 covers up to 1 cc, and 11952 covers 5.1–10 cc.

What documentation supports reporting this service?

Record the clinical reason for correcting the contour defect, the treatment site, the filling material, and the volume injected. Medicare payment is limited to specific circumstances.

Is same-day preoperative or postoperative care separately billable?

The 0-day global period includes same-day preoperative and postoperative care for this procedure.

Should modifier 50 be used for treatment on both sides?

No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this code.

How are other procedures in the same session paid?

The highest-valued procedure is paid in full, and other procedures in the same session are subject to the standard multiple-procedure reduction.

Can an assistant surgeon or co-surgeon be reported?

Assistant-at-surgery payment is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
