Acquired clawhand, left hand

This code signifies a non-congenital deformity of the left hand where the fingers are permanently flexed at the interphalangeal joints and hyperextended at the metacarpophalangeal joints, resembling a claw. This condition typically results from nerve damage, muscle imbalance, or contractures.

Apply this code when documentation explicitly states "acquired clawhand" affecting the patient's left hand. This often arises from conditions like ulnar nerve palsy, leprosy, or ischemic contractures. Ensure the medical record clearly specifies the laterality.

• Distinguish from congenital deformities; this code is strictly for acquired conditions.
• Always confirm laterality (left hand) as separate codes exist for the right and unspecified hands.
• Code any underlying cause (e.g., nerve injury, leprosy) as a primary diagnosis if it led to the clawhand.
