Pilonidal cyst with abscess
ICD-10 L05.01 is a billable code used to indicate a diagnosis of pilonidal cyst with abscess.
A pilonidal cyst with abscess is a common condition that occurs in the sacrococcygeal region, characterized by the formation of a cystic structure that can become infected and filled with pus. Clinically, patients may present with pain, swelling, and tenderness in the lower back area, often accompanied by fever and malaise if an abscess develops. The anatomy involved includes the skin and subcutaneous tissue around the coccyx, where hair follicles can become obstructed, leading to the formation of the cyst. Disease progression can vary; while some patients may remain asymptomatic, others may experience recurrent infections and complications. Diagnostic considerations include a thorough physical examination, imaging studies such as ultrasound if the abscess is suspected, and sometimes aspiration to confirm the presence of pus. Treatment typically involves incision and drainage of the abscess, and in recurrent cases, surgical excision of the cyst may be necessary to prevent future occurrences.

L05.01 specifically covers pilonidal cysts that have developed into an abscess. This includes cases where the cyst is inflamed, infected, and filled with pus, leading to significant discomfort and potential systemic symptoms.
L05.01 should be used when there is clear evidence of an abscess associated with a pilonidal cyst. If the cyst is present without signs of infection or abscess formation, L05.00 should be utilized instead.
Documentation should include a detailed clinical examination noting the presence of an abscess, any imaging studies performed, treatment plans, and follow-up notes that indicate the management of the abscess.
