Pressure ulcer of left heel, unspecified stage

This code signifies a pressure-induced localized injury to the skin and underlying tissue on the left heel, where the specific stage of the ulceration has not been documented by the provider. It indicates tissue damage resulting from prolonged pressure, shear, or friction.

Apply this code when documentation explicitly states a pressure ulcer is present on the left heel, but the provider has not specified the stage (e.g., "left heel pressure ulcer, stage unknown," "unstageable left heel decubitus"). This code is appropriate when the clinical information is insufficient to assign a more specific stage.

• Always query the provider for a specific stage if not documented, as more specific codes exist for each stage (L89.621-L89.624, L89.626, L89.629).
• Do not use this code if the documentation indicates an unstageable pressure ulcer due to slough or eschar; use L89.626 (unstageable pressure ulcer of left heel).
• Sequence this code as a secondary diagnosis when the pressure ulcer is a complication of another condition, or as a primary diagnosis if it is the reason for the encounter.
