Lobster-claw right hand

This code describes a congenital malformation of the right hand characterized by a deep central cleft, giving the hand a claw-like appearance. It typically involves the absence or fusion of central digits (usually the third and fourth rays), with the thumb and fifth digit often being present and separated by the cleft.

Use this code when documentation clearly indicates a congenital "lobster-claw" deformity specifically affecting the patient's right hand. This diagnosis is typically made at birth or early childhood based on physical examination and imaging studies.

• Ensure the documentation specifies the right hand; separate codes exist for the left hand and bilateral involvement.
• Do not confuse this with other congenital hand malformations like syndactyly or polydactyly, which have distinct ICD-10-CM codes.
• Consider additional codes for any associated congenital anomalies or functional impairments, if documented.
