What 29580 covers
A clinician applies a zinc oxide-impregnated dressing and compression wrap to the lower leg, commonly as part of care for venous stasis ulcers or related edema. The service is seen in wound-care clinics, vascular practices, podiatry offices, and outpatient settings. The wrap supports compression treatment; it is distinct from immobilizing the leg in a splint or applying a different multilayer compression system.
Report 29580 for the Unna boot application, with documentation identifying the treated leg, the condition prompting compression, and the dressing and wrap applied. CMS assigns a 0-day global period, so 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 other procedures are paid at 50%. For bilateral service, modifier 50 is paid at 150%. An assistant at surgery is not paid; co-surgeons and team surgery are not permitted.

29580 billing questions
How is 29580 different from 29581?
Use 29580 for an Unna boot dressing. Code 29581 describes application of a multilayer compression system, a different compression method.
What documentation supports 29580?
Record the treated leg, the condition requiring compression, and that an Unna boot dressing was applied. Document laterality when only one leg is treated.
Can 29580 be reported for both legs?
For bilateral service, CMS pays the service with modifier 50 at 150%. Document the application on both legs.
Is same-day evaluation and management included?
The 0-day global period includes same-day preoperative and postoperative care. The application itself remains reportable when performed.
How does a splint differ from an Unna boot?
An Unna boot provides compression through a zinc oxide dressing and wrap. A lower-leg splint, such as 29515, is used for immobilization.
Can an assistant or co-surgeon be reported?
CMS does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.
