ICD-10 Code L97.529 – Non-pressure chronic ulcer of other part of left foot with unspecified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.529 – Non-pressure chronic ulcer of other part of left foot with unspecified severity
What it is
This code identifies a chronic, non-pressure ulcer located on another part of the left foot, with severity not documented. It is used when the record confirms a persistent skin breakdown but does not specify depth or other severity details.
Clinical signs
Typical findings include an open foot wound that fails to heal and may show drainage, surrounding skin changes, or exposed tissue. Clinical features vary; refer to documentation.
When to use this code
Use this code when the chart clearly states a chronic ulcer on the left foot and the site is not the heel, midfoot, or other more specific listed location. Use it when severity is not documented or cannot be determined from the record.
It is appropriate for outpatient, inpatient, or wound-care documentation that confirms a non-pressure ulcer of the left foot. If laterality, site, or severity is more specific, code the documented detail instead.
Do not use for
Do not use this code for pressure ulcers, diabetic foot ulcers without documentation of a non-pressure ulcer, or ulcers on a different foot or body site. Check documentation.
Coding tip
Verify the exact left-foot location and whether severity is stated before assigning L97.529.
