ICD-10 Code L97.829 – Non-pressure chronic ulcer of other part of left lower leg with unspecified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.829 – Non-pressure chronic ulcer of other part of left lower leg with unspecified severity
What it is
This code identifies a chronic, non-pressure ulcer on the left lower leg in a site other than the calf, ankle, or heel. Use it when the record states the ulcer’s location on the other part of the left lower leg but does not specify severity.
Clinical signs
Typical findings include an open skin lesion that persists over time, with local tissue breakdown and delayed healing. Clinical features vary; refer to documentation for depth, drainage, infection, or whether bone, tendon, or muscle is involved.
When to use this code
Use this code when the provider documents a chronic non-pressure ulcer on the other part of the left lower leg and does not assign a more specific severity category. It is appropriate for charted wounds described as long-standing ulcers of the left lower leg outside the calf, ankle, or heel. Confirm laterality and exact anatomic site before coding.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers on a different leg or body site. Check documentation if the ulcer location is the calf, ankle, heel, or if severity is specified more precisely.
Coding tip
Verify both laterality and exact site wording; “other part” is a location-specific term, not a substitute for missing documentation.
