Pressure ulcer of head, stage 1

This code signifies the earliest stage of a pressure-induced skin and tissue injury located on the head. It presents as intact skin with non-blanchable redness, indicating localized damage, typically over a bony prominence. The skin may also appear discolored, warm, or firm compared to surrounding tissue.

Apply this code when documentation clearly indicates a stage 1 pressure ulcer affecting any part of the head (e.g., occiput, ear). Supporting documentation should describe non-blanchable erythema on intact skin, along with the specific anatomical site on the head. This code is appropriate for initial assessment and ongoing management of this specific wound stage.

• Ensure the documentation explicitly states "stage 1" and specifies the head as the anatomical location.
• Do not use this code for other stages of pressure ulcers or for non-pressure-related skin conditions on the head.
• Always sequence this code after the primary diagnosis or condition that led to the patient's immobility, if applicable.
