ICD-10 Code L97.818 – Non-pressure chronic ulcer of other part of right lower leg with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.818 – Non-pressure chronic ulcer of other part of right lower leg with other specified severity
What it is
This code identifies a chronic, non-pressure ulcer on another part of the right lower leg. Use it when the record specifies the ulcer’s location and severity, but not a more specific ulcer type.
Clinical signs
Typical findings include a persistent open skin lesion on the right lower leg with delayed healing. Clinical features vary; refer to documentation for the ulcer’s depth, drainage, and severity wording.
When to use this code
Use L97.818 when the provider documents a chronic ulcer of the right lower leg in a site other than ankle, heel, or foot, and describes it as “other specified severity.” It also fits when the note confirms a non-pressure ulcer and gives enough detail to support this exact code. Check documentation if the severity term is unclear.
Do not use for
Do not use this code for pressure ulcers, ulcers of the foot, heel, or ankle, or ulcers on the left lower leg. If the chart does not specify the right lower leg or the severity category, check documentation.
Coding tip
Match the code to both the exact anatomic site and the documented severity phrase; missing either detail can change the final code.
