ICD-10 Code L97.92 – Non-pressure chronic ulcer of unspecified part of left lower leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.92 – Non-pressure chronic ulcer of unspecified part of left lower leg
What it is
This code identifies a chronic, non-pressure ulcer on the left lower leg when the exact site is not further specified. It is used for an open skin lesion caused by poor healing, not by pressure injury.
Clinical signs
Typical findings include a persistent open sore, drainage, delayed healing, and surrounding skin changes such as redness or swelling. Clinical features vary; refer to documentation.
When to use this code
Use L97.92 when the record clearly documents a chronic non-pressure ulcer of the left lower leg but does not identify a more precise location. You should also use it when the ulcer is described as non-pressure and chronic, and laterality is left. Check documentation if the note suggests a different ulcer type or site.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers on another limb or body site. It is also incorrect if the chart specifies a more exact left lower leg location that requires a different code. Check documentation.
Coding tip
Confirm that the ulcer is chronic, non-pressure, and left-sided before assigning L97.92.
