Frontal fibrosing alopecia
ICD-10 L66.12 is a billable code used to indicate a diagnosis of frontal fibrosing alopecia.
Frontal fibrosing alopecia (FFA) is a form of scarring alopecia characterized by progressive hair loss primarily affecting the frontal hairline and often the eyebrows. Clinically, it presents as a symmetrical recession of the frontal hairline, with associated symptoms such as pruritus or burning sensation in the affected areas. The condition predominantly affects postmenopausal women, although it can occur in men and younger individuals as well. The underlying pathology involves lymphocytic infiltration of the hair follicles, leading to follicular destruction and subsequent scarring. Disease progression can vary, with some patients experiencing rapid hair loss while others may have a more indolent course. Diagnosis is typically made through clinical examination and may be supported by scalp biopsy, which reveals characteristic histopathological findings such as lymphocytic infiltrate and fibrosis around hair follicles. Differential diagnoses include other forms of alopecia, such as androgenetic alopecia and alopecia areata, making accurate diagnosis crucial for effective management.

L66.12 specifically covers frontal fibrosing alopecia, which is characterized by hair loss at the frontal hairline and may also involve the eyebrows. It is distinct from other alopecias due to its scarring nature and demographic prevalence.
L66.12 should be used when the clinical presentation aligns with frontal fibrosing alopecia, particularly when there is evidence of scarring and lymphocytic infiltration. It is important to differentiate it from other alopecia types, such as L66.1 for alopecia areata, which does not involve scarring.
Documentation should include a thorough clinical examination, patient history, and, if applicable, results from a scalp biopsy showing characteristic histopathological features. Detailed notes on symptomatology and treatment response are also essential.
