ICD-10 Code L97.922 – Non-pressure chronic ulcer of unspecified part of left lower leg with fat layer exposed (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.922 – Non-pressure chronic ulcer of unspecified part of left lower leg with fat layer exposed
What it is
This code identifies a chronic, non-pressure ulcer on the left lower leg where the wound extends through skin into the subcutaneous fat layer. Use it when the documentation specifies the left lower leg but not a more exact site.
Clinical signs
Typical findings include a persistent open sore with exposed fat tissue, delayed healing, and localized drainage or surrounding skin changes. Clinical features vary; refer to documentation.
When to use this code
Use L97.922 when the record clearly states a non-pressure chronic ulcer of the unspecified part of the left lower leg and notes fat layer exposure. It applies when the ulcer is chronic and not caused by pressure. If the site is more specific, code that more specific location instead.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers on another limb or body site. Check documentation if the depth, laterality, or exact location is unclear.
Coding tip
Verify both laterality and depth, because “fat layer exposed” changes the code selection.
