ICD-10 Code L97.12 – Non-pressure chronic ulcer of left thigh (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.12 – Non-pressure chronic ulcer of left thigh
What it is
This code identifies a chronic, non-pressure ulcer located on the left thigh. Use it when the wound is not caused by pressure and documentation specifies the left thigh.
Clinical signs
Typical findings include an open skin lesion with delayed healing, drainage, or surrounding tissue breakdown. Clinical features vary; refer to documentation.
When to use this code
Use L97.12 when the provider documents a chronic ulcer on the left thigh and clearly states it is non-pressure related. It may appear in notes describing a long-standing wound, skin loss, or ulceration at that site. Confirm laterality and location in the record.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers on another body site. If the documentation does not confirm the left thigh or non-pressure cause, check documentation.
Coding tip
Verify that the ulcer is chronic and non-pressure, and that the documentation supports the left thigh site before assigning L97.12.
