ICD-10 Code L97.508 – Non-pressure chronic ulcer of other part of unspecified foot with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.508 – Non-pressure chronic ulcer of other part of unspecified foot with other specified severity
What it is
This code identifies a chronic, non-pressure ulcer on another part of an unspecified foot, with severity documented as “other specified.” Use it when the record describes a persistent foot ulcer but does not specify a more exact site or severity category.
Clinical signs
Typical findings include an open wound on the foot with delayed healing, drainage, or surrounding skin breakdown. Clinical features vary; refer to documentation for the exact location and severity descriptors.
When to use this code
Use L97.508 when the provider documents a chronic foot ulcer that is not caused by pressure and the site is not otherwise specified more precisely. It also fits when the ulcer is on another part of the foot and the severity is documented as “other specified.”
Choose this code only when laterality or a more specific foot location is not available in the note. If the ulcer is described with a different severity or a more exact site, check documentation before assigning L97.508.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers of a different anatomic site. Do not use it when documentation supports a more specific non-pressure foot ulcer code.
Coding tip
Verify the ulcer’s cause, chronicity, site, and severity in the note before coding, and query the provider if “other specified” is unclear.
