ICD-10 Code L97.22 – Non-pressure chronic ulcer of left calf (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.22 – Non-pressure chronic ulcer of left calf
What it is
This code identifies a chronic ulcer on the left calf that is not caused by pressure. It is used for a long-lasting open sore in that location, regardless of the underlying cause, when documentation specifies the left calf.
Clinical signs
Typical findings include a persistent skin break or open wound on the left calf with delayed healing. Clinical features vary; refer to documentation for depth, drainage, infection, and whether surrounding tissue is inflamed.
When to use this code
Use L97.22 when the record clearly documents a non-pressure chronic ulcer limited to the left calf. You should also confirm any additional detail about ulcer severity or associated conditions if the note supports it. If laterality or site is unclear, check documentation.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers on another leg site. If the chart does not specify the left calf, or the lesion is not chronic, check documentation before coding.
Coding tip
Verify both laterality and anatomic site, because “left calf” is specific and should not be assumed from nearby lower-leg wording.
