ICD-10 Code L97.929 – Non-pressure chronic ulcer of unspecified part of left lower leg with unspecified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.929 – Non-pressure chronic ulcer of unspecified part of left lower leg with unspecified severity
What it is
This code identifies a chronic, non-pressure ulcer on the left lower leg when the exact site and severity are not documented. Use it for a persistent skin breakdown that is not caused by pressure.
Clinical signs
Typical findings include an open sore, delayed healing, drainage, or surrounding skin changes on the left lower leg. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record confirms a chronic ulcer on the left lower leg but does not specify the exact location within the lower leg or the ulcer depth/severity. It also fits when the provider documents “non-pressure chronic ulcer” and laterality is left, but details remain incomplete. Check documentation if the note is ambiguous.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers on a different leg or body site. If the record specifies a more exact location or severity, code that documented option instead.
Coding tip
Verify laterality, chronicity, and ulcer severity in the provider note before assigning this unspecified code.
