Pilonidal cyst without abscess
ICD-10 L05.91 is a billable code used to indicate a diagnosis of pilonidal cyst without abscess.
A pilonidal cyst without abscess is a common skin condition that typically occurs in the sacrococcygeal region, characterized by the formation of a cyst or cavity in the skin that may contain hair and skin debris. Clinically, patients may present with discomfort, pain, or swelling in the affected area, particularly when sitting or during physical activity. The cyst can develop due to hair follicles becoming clogged with hair and debris, leading to inflammation and the formation of a cyst. The condition may progress to form a pilonidal abscess if left untreated, which is characterized by increased pain, redness, and the presence of pus. Diagnosis is primarily clinical, based on the physical examination and patient history, although imaging may be used in complicated cases. Differential diagnoses include other skin lesions or infections in the gluteal region. Treatment typically involves conservative management, such as warm compresses and hygiene measures, or surgical intervention for recurrent or symptomatic cases.

L05.91 specifically covers pilonidal cysts that are not complicated by abscess formation. It is important to differentiate this from L05.90, which includes abscesses, as treatment and management differ significantly.
L05.91 should be used when a patient presents with a pilonidal cyst that is not infected or abscessed. If there are signs of infection or abscess, L05.90 should be selected instead.
Documentation should include a detailed history of the patient's symptoms, physical examination findings, and any treatment provided. Notes should clearly indicate the absence of abscess formation to justify the use of L05.91.
