What This Code Means
L97 is the ICD-10-CM diagnosis code for non-pressure chronic ulcer of lower limb, not elsewhere classified. L97 sits in the ICD-10-CM chapter for diseases of the skin and subcutaneous tissue (l00-l99), within the section covering other disorders of the skin and subcutaneous tissue (l80-l99).
Header codes like L97 cannot be reported on claims directly; they organize child codes that share clinical context. Coders should select the billable child code that matches the documented presentation and then verify its current source-backed HCC mapping. Do not infer a child code or risk adjustment value from the header alone.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for L97 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
