ICD-10 Code L97.808 – Non-pressure chronic ulcer of other part of unspecified lower leg with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.808 – Non-pressure chronic ulcer of other part of unspecified lower leg with other specified severity
What it is
This code identifies a chronic, non-pressure ulcer on another specified part of an unspecified lower leg, with severity documented as “other specified.” Use it when the record clearly describes the ulcer site and severity but does not name the exact lower-leg side or precise severity category.
Clinical signs
Typical findings include a persistent open sore on the lower leg with delayed healing, drainage, or surrounding skin changes. Clinical features vary; refer to documentation for the exact location, laterality, and severity terms used.
When to use this code
Use L97.808 when the provider documents a chronic non-pressure ulcer on an unspecified lower leg site and specifies a severity that is not captured by the more common severity options. It is appropriate when the note supports a chronic ulcer diagnosis and the location is not better reported with a more specific code. Check documentation if the chart is unclear about laterality or ulcer depth.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers of the foot or ankle. Do not assign it if the record supports a more specific lower-leg ulcer code.
Coding tip
Confirm the exact ulcer site and the documented severity phrase before coding, because unspecified laterality or a more specific location may change the code.
