What 11952 covers

This service covers placement of injectable filling material into subcutaneous tissue to restore contour or fill a soft-tissue depression. The code level is selected by the total volume injected, with 11952 representing 5.1 through 10 cc. Dermatologists and plastic surgeons commonly perform it in an office or outpatient procedure setting, injecting material at one or more sites. The record should identify the treated defect, anatomical site, material, and amount delivered; distinguish this service from injections placed within a skin lesion.

Medicare lists payment as restricted to specific circumstances, so the record must support the covered clinical indication. This is a minor procedure with a 0-day global period: same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others at 50%. The code is volume-based rather than bilateral, so 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.

11952 billing questions

How is 11952 distinguished from 11951 or 11954?

Choose the code by the total volume of filling material injected: 11952 covers 5.1 through 10 cc. The neighboring codes represent lower or higher volume ranges.

Is volume counted separately for each injection site?

Select the code based on the total volume injected for the service, rather than assigning a separate volume tier to each injection point. Document the amount delivered.

Can modifier 50 be used when treatment is performed on both sides?

No. CMS identifies bilateral adjustment as inappropriate for this code; report the volume-based service without modifier 50.

How does 11952 differ from 11900 or 11901?

11952 describes subcutaneous placement of filling material selected by volume. Codes 11900 and 11901 are for injections into skin lesions, selected by the number of lesions.

What documentation supports 11952?

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.
