Superficial frostbite of left hip and thigh, sequela

This code indicates a past episode of superficial frostbite affecting the left hip and thigh, where the effects of the injury are still present and being addressed. Superficial frostbite involves damage to the skin and subcutaneous tissue, but not deeper structures. "Sequela" signifies that the current encounter is for a residual condition or complication arising from the original frostbite.

Apply this code when a patient presents for treatment or evaluation of a long-term consequence of superficial frostbite to the left hip and thigh. This could include ongoing pain, numbness, altered sensation, skin discoloration, or other persistent issues directly attributable to the prior frostbite injury. It is used after the initial acute phase of frostbite has resolved.

• Always use this code as a secondary diagnosis, following a code for the specific sequela being treated (e.g., chronic pain, paresthesia).
• The "S" in the 7th character indicates sequela; ensure this is consistently applied for residual conditions.
• Verify laterality (left hip and thigh) and depth (superficial) are accurately documented to support this specific code.
