ICD-10 Code L97.809 – Non-pressure chronic ulcer of other part of unspecified lower leg with unspecified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.809 – Non-pressure chronic ulcer of other part of unspecified lower leg with unspecified severity
What it is
This code identifies a chronic, non-pressure ulcer on another part of an unspecified lower leg. Use it when the record confirms a lower-leg ulcer but does not specify the exact side, location, or severity.
Clinical signs
Typical findings include an open skin lesion on the lower leg that persists over time and is not caused by pressure. Clinical features vary; refer to documentation for laterality, exact site, and depth if recorded.
When to use this code
Use L97.809 when the provider documents a chronic ulcer of the lower leg and does not identify a more specific location or severity. It is appropriate when the ulcer is clearly non-pressure and the chart lacks enough detail for a more precise code. If the note later specifies side, site, or severity, code to the most specific option available.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers with a documented more specific lower-leg site. Check documentation if the ulcer is described as diabetic, arterial, venous, or traumatic, because another code set may apply.
Coding tip
Query for laterality, exact location, and severity before defaulting to this unspecified code.
