Lobster-claw left hand

This code describes a congenital malformation of the left hand characterized by a deep median cleft, giving the appearance of a lobster claw. This condition, also known as ectrodactyly, involves the absence or hypoplasia of central digits, typically the second, third, and/or fourth fingers, with fusion of the remaining digits.

Assign this code for patients diagnosed with congenital split hand malformation affecting the left hand. Documentation should clearly specify the "lobster-claw" deformity or ectrodactyly of the left hand. This code is appropriate for initial diagnosis, follow-up care, and surgical planning related to this specific congenital anomaly.

• Ensure the laterality is explicitly documented as "left hand" to support this specific code.
• Do not confuse with other congenital hand malformations like syndactyly or polydactyly, which have distinct codes.
• Consider additional codes for any associated congenital anomalies or functional impairments.
