Lobster-claw hand, bilateral

This code describes a congenital malformation affecting both hands, characterized by a deep cleft extending into the palm, often with the absence of central digits (typically the third digit). The remaining digits may be fused, giving the hand a claw-like appearance resembling a lobster's pincer. This condition is also known as ectrodactyly or split hand malformation.

Use this code when documentation explicitly states a diagnosis of bilateral lobster-claw hand or bilateral split hand malformation. This code is appropriate for initial diagnoses, follow-up care, and surgical planning related to this specific congenital anomaly. Ensure the medical record clearly indicates the bilateral involvement.

• Confirm documentation specifies bilateral involvement; unilateral presentation would require a different code.
• Do not confuse with other congenital hand malformations that do not involve the characteristic deep central cleft and absent digits.
• Consider sequencing this code as a primary diagnosis when it is the main reason for the encounter, or as a secondary diagnosis when addressing related complications or interventions.
