ICD-10 Code L97.908 – Non-pressure chronic ulcer of unspecified part of unspecified lower leg with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.908 – Non-pressure chronic ulcer of unspecified part of unspecified lower leg with other specified severity
What it is
This code identifies a chronic, non-pressure ulcer on an unspecified area of an unspecified lower leg, with severity that does not fit the more specific ulcer-depth categories. Use it when the record confirms a lower-leg ulcer but does not specify location or exact depth.
Clinical signs
Typical findings include an open, non-healing skin lesion on the lower leg with chronicity documented. Clinical features vary; refer to documentation for ulcer location, laterality, and severity details.
When to use this code
Use L97.908 when the provider documents a chronic lower-leg ulcer and does not identify the exact site or specify a more precise ulcer severity code. It is appropriate when the ulcer is non-pressure and not due to trauma, burn, or another excluded cause. Check documentation if the record suggests a more specific ulcer category.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers with a documented more specific location or depth. If the cause is diabetic, arterial, venous, or otherwise specified elsewhere, code the documented condition instead.
Coding tip
Confirm whether the chart gives laterality, exact lower-leg site, and ulcer depth before defaulting to this unspecified code.
