Code Description

ICD-10 M21.53 is a billable code used to indicate a diagnosis of acquired clawfoot.

Key Diagnostic Point:

Acquired clawfoot is a deformity characterized by hyperextension of the metatarsophalangeal joints and flexion of the proximal and distal interphalangeal joints of the toes, resulting in a claw-like appearance. This condition can arise from various underlying causes, including neurological disorders, trauma, or prolonged pressure on the feet. Unlike congenital clawfoot, which is present at birth, acquired clawfoot develops later in life, often due to conditions such as diabetes, stroke, or peripheral neuropathy. Patients may experience pain, difficulty walking, and an increased risk of foot ulcers due to abnormal pressure distribution. Treatment options may include orthotic devices, physical therapy, and in some cases, surgical intervention to correct the deformity and alleviate symptoms. Understanding the etiology and management of acquired clawfoot is essential for accurate diagnosis and coding, as it can significantly impact patient care and outcomes.
