L97.506 — Non-pressure chronic ulcer of other part of unspecified foot with bone involvement without evidence of necrosis
Is L97.506 billable?
Yes, but L97.506 is an unspecified code. L97.506 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, L97.506 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting L97.506 — the more specific alternatives are listed below.

Which MS-DRGs does L97.506 group to?
L97.506 sits in MDC 09 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 573Skin Graft for Skin Ulcer or Cellulitis with MCCsurgical
- 574Skin Graft for Skin Ulcer or Cellulitis with CCsurgical
- 575Skin Graft for Skin Ulcer or Cellulitis without CC/MCCsurgical
As a secondary diagnosis, L97.506 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
