Keratosis follicularis et parafollicularis in cutem penetrans
ICD-10 L87.0 is a billable code used to indicate a diagnosis of keratosis follicularis et parafollicularis in cutem penetrans.
Keratosis follicularis et parafollicularis in cutem penetrans, commonly known as 'follicular keratosis,' is a dermatological condition characterized by the abnormal proliferation of keratinocytes within hair follicles. Clinically, it presents as small, keratotic papules that can be skin-colored or slightly erythematous, often found on the trunk and extremities. The condition is associated with the obstruction of hair follicles, leading to the retention of keratin and subsequent inflammation. The disease progression can vary; while some patients may experience stable lesions, others may see an increase in the number and size of papules over time. Diagnostic considerations include a thorough clinical examination and, if necessary, a biopsy to rule out other follicular disorders. The condition is often benign but can be mistaken for other skin disorders, necessitating careful evaluation to ensure accurate diagnosis and management.

L87.0 specifically covers keratosis follicularis et parafollicularis, which includes conditions characterized by keratin buildup in hair follicles, leading to papular lesions. It is important to differentiate it from other keratotic disorders such as keratosis pilaris and actinic keratosis.
L87.0 should be used when the clinical presentation aligns with keratosis follicularis et parafollicularis, particularly when lesions are localized to hair follicles and exhibit characteristic features. If the lesions are more diffuse or involve other skin layers, alternative codes may be more appropriate.
Documentation should include a detailed clinical history, physical examination findings, and any relevant diagnostic tests such as skin biopsies. Photographic evidence may also be beneficial to support the diagnosis and treatment plan.
