Pressure ulcer of left upper back, stage 1

This code describes an early-stage pressure injury located on the left upper back. It indicates non-blanchable erythema of intact skin, which is the first observable sign of tissue damage due to sustained pressure. The skin remains unbroken, but the underlying tissue has been compromised.

Use this code when documentation clearly identifies a pressure ulcer on the patient's left upper back that presents as non-blanchable redness with intact skin. This stage signifies superficial damage, often reversible with appropriate intervention. Supporting documentation should include the specific anatomical site, the stage of the ulcer, and a clear diagnosis of a pressure ulcer.

• Ensure the documentation specifies "left upper back" and "stage 1" to accurately assign this code.
• Differentiate from other skin conditions like dermatitis or rashes, which are not pressure ulcers.
• Always sequence this code as a secondary diagnosis when the pressure ulcer is a comorbidity or complication of another primary condition.
