Alopecia universalis

This code represents a severe form of alopecia areata characterized by complete loss of all hair on the scalp and body. It is an autoimmune condition where the immune system mistakenly attacks hair follicles, leading to widespread hair loss. The condition is typically chronic and can significantly impact a patient's quality of life.

Use this code when documentation clearly indicates a diagnosis of alopecia universalis, signifying total body hair loss due to an autoimmune process. This diagnosis is typically made by a dermatologist based on clinical examination and patient history. Supporting documentation should explicitly state "alopecia universalis" or describe complete hair loss of the scalp, face, and body.

• Differentiate from other forms of alopecia, such as alopecia totalis (complete scalp hair loss only) or alopecia areata (patchy hair loss).
• Do not use for hair loss due to chemotherapy, radiation, or other medical treatments; specific codes exist for those etiologies.
• Consider any associated autoimmune conditions that may be documented, as these could require additional coding.
