Pressure ulcer of unspecified ankle, stage 1

This code signifies the earliest stage of a pressure ulcer (also known as a pressure injury or bed sore) located on an unspecified ankle. At stage 1, the skin is intact but presents with non-blanchable redness, indicating localized damage to the underlying soft tissue.

Apply this code when documentation confirms a stage 1 pressure ulcer on either the left or right ankle, and the specific ankle is not documented. This diagnosis is supported by findings of persistent erythema that does not lighten with pressure, typically in a bony prominence area of the ankle.

• Ensure the documentation clearly states "stage 1" and specifies the ankle as the anatomical site.
• If the laterality (left or right ankle) is specified, a more specific code should be used.
• Always sequence this code after any underlying condition contributing to the pressure ulcer, such as immobility or altered sensory perception.
