ICD-10 Code L89.329 – Pressure ulcer of left buttock, unspecified stage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.329 – Pressure ulcer of left buttock, unspecified stage
What it is
This code identifies a pressure ulcer located on the left buttock when the stage is not documented. Use it for a localized skin and tissue injury caused by prolonged pressure over that area.
Clinical signs
Findings may include an open sore, skin breakdown, tenderness, drainage, or discoloration over the left buttock. Clinical features vary; refer to documentation for the ulcer depth and stage.
When to use this code
Use L89.329 when the record clearly states a pressure ulcer of the left buttock and does not specify a stage. It is appropriate for wound assessments, inpatient notes, or outpatient documentation that confirms the site. If staging is later documented, code the more specific stage instead.
Do not use for
Do not use this code for pressure ulcers at another body site or for ulcers with a documented stage that should be coded more specifically. Do not apply it when documentation says the lesion is not a pressure ulcer; check documentation.
Coding tip
Confirm both laterality and staging in the chart before assigning this code.
