Blister (nonthermal), unspecified hip, subsequent encounter

This code describes a non-burn related blister located on an unspecified hip, indicating that the patient is receiving follow-up care for the initial injury. It signifies a superficial skin lesion characterized by a fluid-filled sac, not caused by heat or cold, on the hip region.

Use this code for subsequent encounters when a patient presents for ongoing management, dressing changes, or re-evaluation of a non-thermal blister on the hip. This applies after the initial treatment has been rendered and the patient is in the healing phase.

• Ensure the documentation clearly states "subsequent encounter" for the blister.
• Verify the blister is explicitly non-thermal and located on the hip.
• If the specific hip (left or right) is documented, choose a more specific code.
