Polydactyly (Q69)

ICD-10 code Q69 covers polydactyly, a congenital condition characterized by extra fingers or toes. This section includes precise codes to identify the type and location of accessory digits, aiding accurate diagnosis and documentation.

Specifically, Q69.0 is used for accessory fingers, capturing variations such as bilateral polydactyly of index fingers or central and postaxial types. The code Q69.1 refers to accessory thumbs, often called radial polydactyly or triphalangeal thumb in clinical terms. Meanwhile, Q69.2 applies to accessory toes, including preaxial, postaxial, and mesoaxial types. For cases where the type or location is unspecified, Q69.9 is used; this code also encompasses complex syndromes linked to polydactyly, like short rib polydactyly and other multisystem congenital anomalies. Coders looking for the ICD-10 code for polydactyly should note these distinctions to ensure precise coding based on the affected digit(s) and associated conditions.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Polydactyly

A congenital anomaly of the hand or foot, marked by the presence of supernumerary digits.

Short Rib-Polydactyly Syndrome

A syndrome inherited as an autosomal recessive trait and incompatible with life. The main features are narrow thorax, short ribs, scapular and pelvic dysplasia, and polydactyly.

Smith-Lemli-Opitz Syndrome

An autosomal recessive disorder of CHOLESTEROL metabolism. It is caused by a deficiency of 7-dehydrocholesterol reductase, the enzyme that converts 7-dehydrocholesterol to cholesterol, leading to an abnormally low plasma cholesterol. This syndrome is characterized by multiple CONGENITAL ABNORMALITIES, growth deficiency, and INTELLECTUAL DISABILITY.
