What 11950 covers
Code 11950 represents injection of a small amount of filling material into subcutaneous tissue to add volume or improve a contour depression. A dermatologist or plastic surgeon typically performs it in an office or outpatient procedure setting. The material is placed beneath the skin, rather than injected into a skin lesion for medication treatment. This volume tier covers 1 cc or less.
Medicare payment is restricted to specific circumstances, so the record should identify the medical indication, treated area, material, and volume. Choose the volume tier based on the amount injected, not the number of needle passes. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and the others are paid at 50%. Modifier 50 is inappropriate for this descriptor. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.

11950 billing questions
How is 11950 distinguished from 11951?
11950 is the volume tier for 1 cc or less. Use 11951 when the injected volume is 1.1 to 5.0 cc.
Is the code selected per injection site or by volume?
Select the tier based on the volume of filling material injected, not the number of injection sites or needle passes. Document the amount used.
Can 11950 be reported with an injection for a skin lesion?
The services have different targets: 11950 concerns subcutaneous filling material, while 11900 concerns medication injected into skin lesions. Report the service actually performed.
What documentation supports Medicare payment?
Document the medical indication, treated area, filling material, and volume. Medicare payment is restricted to specific circumstances.
Does modifier 50 apply when filler is injected on both sides?
No. Modifier 50 is inappropriate for this descriptor; report the applicable service based on the volume injected.
Are same-day services and surgical assistance handled separately?
Same-day preoperative and postoperative care is included in the 0-day global period. Assistant-at-surgery payment requires medical-necessity documentation; co-surgeons and team surgery are not permitted.
