ICD-10 Code L97.325 – Non-pressure chronic ulcer of left ankle with muscle involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.325 – Non-pressure chronic ulcer of left ankle with muscle involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the left ankle that extends into muscle but shows no necrotic tissue. Use it when the record clearly documents the ulcer location, depth, and absence of necrosis.
Clinical signs
Typical findings include an open wound at the left ankle with prolonged healing and exposure of muscle tissue. Clinical features vary; refer to documentation for laterality, depth, and whether necrosis is absent.
When to use this code
Use L97.325 when the provider documents a chronic non-pressure ulcer of the left ankle involving muscle and specifically states there is no evidence of necrosis. You should also confirm that the ulcer is not described as pressure-related. If depth or laterality is unclear, check documentation before coding.
Do not use for
Do not use this code for pressure ulcers, ulcers without muscle involvement, or ulcers with necrotic tissue. Check documentation if the site is not the left ankle or if the ulcer depth is not specified.
Coding tip
Verify laterality, depth, and necrosis status in the provider note before assigning L97.325.
