Code Description

ICD-10 M21.512 is a billable code used to indicate a diagnosis of acquired clawhand, left hand.

Key Diagnostic Point:

Acquired clawhand, also known as claw hand deformity, is characterized by a specific hand posture where the fingers are flexed at the metacarpophalangeal joints and extended at the interphalangeal joints, resembling a claw. This condition typically arises from neurological or muscular disorders that affect the intrinsic muscles of the hand, leading to an imbalance between the flexor and extensor muscles. Common causes include trauma, stroke, or conditions such as multiple sclerosis or peripheral neuropathy. The left hand is specifically affected in this code, indicating the need for targeted treatment and rehabilitation strategies. Patients may experience difficulties with grip strength, fine motor skills, and overall hand function, impacting daily activities. Treatment often involves physical therapy, splinting, and in some cases, surgical intervention to restore function and improve aesthetics. Understanding the underlying cause is crucial for effective management and coding accuracy.
