ICD-10 Code L97.10 – Non-pressure chronic ulcer of unspecified thigh (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.10 – Non-pressure chronic ulcer of unspecified thigh
What it is
This code identifies a chronic, non-pressure ulcer located on the thigh when the laterality or exact site is not specified. Use it for a persistent skin breakdown that is not caused by pressure.
Clinical signs
Typical findings include an open sore with delayed healing, drainage, or surrounding skin changes. Clinical features vary; refer to documentation.
When to use this code
Use L97.10 when the record documents a chronic ulcer of the thigh but does not specify right or left side. It is appropriate when the ulcer is non-pressure in origin and the provider identifies the thigh as the site. Check documentation if the cause, depth, or laterality is unclear.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers on a different body site. If laterality is documented, use the more specific thigh ulcer code instead.
Coding tip
Confirm that the ulcer is chronic and non-pressure, and code the highest documented specificity available.
