Ectrodactyly, often referred to as split-hand/split-foot malformation (SHFM), is classified under ICD-10 code Q71.6 for split-hand and Q72.7 for split-foot, while the legacy ICD-9 code is 755.26. Because Ectrodactyly presents with significant phenotypic variability, clinical documentation often requires additional codes to specify the presence of associated syndromes, such as Ectrodactyly-Ectodermal Dysplasia-Clefting (EEC) syndrome. What is the clinical definition of Ectrodactyly? Ectrodactyly is a rare congenital limb malformation characterized by the deficiency or absence of one or more central digits of the hand or foot.

Ectrodactyly is a rare congenital limb malformation characterized by the deficiency or absence of one or more central digits of the hand or foot. Medically classified as a split-hand/split-foot malformation (SHFM), Ectrodactyly results in a deep median cleft of the affected limb. While the condition can occur in isolation, it is frequently associated with other developmental anomalies. In our community at DiseaseMaps.org, we have seen that individuals living with Ectrodactyly often navigate a unique spectrum of physical experiences, ranging from mild digit syndactyly to more complex limb deficiencies that may require specialized orthopedic intervention.
Medical coding is essential for healthcare providers to track the diagnosis and treatment of Ectrodactyly. These codes ensure that clinical documentation is standardized for insurance billing and epidemiological research. The following codes are most commonly utilized:
The genetic basis of Ectrodactyly is highly complex and heterogeneous. It can be inherited in an autosomal dominant, autosomal recessive, or X-linked manner depending on the underlying genetic mutation, such as those occurring in the TP63 gene. Because Ectrodactyly can present as part of a larger genetic syndrome (like EEC syndrome), clinical geneticists often recommend chromosomal microarray analysis or gene panel testing. Understanding the mode of inheritance is vital for family planning and helps genetic counselors provide accurate risk assessments for parents and siblings.
Management for Ectrodactyly is multidisciplinary, focusing on maximizing the functional use of the hands and feet. For the six members of our DiseaseMaps.org community and many others globally, clinical care teams typically include orthopedic surgeons, hand specialists, physical therapists, and occupational therapists. Surgical intervention for Ectrodactyly is usually considered only when it is expected to significantly improve the mechanical function or grip strength of the hand, rather than for purely cosmetic reasons.
