Frontal fibrosing alopecia

This code identifies a specific form of primary cicatricial alopecia characterized by progressive hair loss along the frontal hairline and eyebrows. It is an inflammatory condition leading to permanent destruction of hair follicles and subsequent scarring.

Assign this code when documentation clearly indicates a diagnosis of frontal fibrosing alopecia, typically confirmed by clinical examination and often supported by biopsy findings. This diagnosis is made by a dermatologist or other qualified healthcare provider.

• Ensure documentation specifies "frontal fibrosing" to differentiate from other forms of alopecia.
• Do not confuse with other types of cicatricial alopecia without specific mention of frontal involvement.
• Consider co-reporting any associated autoimmune conditions if documented.
