About 28003: Multiple-area deep foot infection drainage
Surgical drainage of a deep infection involving multiple foot areas, with possible tendon-sheath involvement, is reported when operative work extends below fascia.
This service involves surgically opening and draining a deep foot infection in multiple areas below the fascia; tendon-sheath involvement may be present. An orthopedic foot-and-ankle surgeon or podiatric surgeon may perform it for a deep abscess, including a diabetic foot infection extending through more than one deep area. The procedure is commonly performed in an operating room or ambulatory surgery setting and differs from drainage confined to a bursa or a single deep area.
Report 28003 when the operative record supports drainage in multiple deep areas. Document the involved sites, extent of infection, and drainage performed. CMS assigns 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 the others at 50%. Bilateral adjustment does not apply, and modifier 50 is inappropriate. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.

28003 billing questions
How does 28003 differ from 28002?
28003 is for drainage involving multiple deep areas of the foot. Use 28002 when the documented drainage is limited to one deep area.
What should the operative report document?
Identify the deep infection sites and describe drainage performed in multiple areas below the fascia. Document any tendon-sheath involvement when present.
Can modifier 50 be used for both feet?
No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 should not be used.
Is same-day postoperative care included?
Yes. The 0-day global period includes same-day preoperative and postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment is restricted for this code. Co-surgeons and team surgery are not permitted.
