    ICD-10-CM Code For Polydactyly: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group Q69 includes congenital malformations involving supernumerary digits (extra fingers or toes) and related variations in digit formation. These ICD-10-CM diagnosis codes are used to document congenital limb anomalies, capturing laterality, specific digit involvement, and associated structural details relevant to surgical planning and clinical follow-up. Accurate coding within the ICD-10-CM Q69 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    When to Use

    Use a code from this group when documenting a congenital extra digit identified at birth or during clinical evaluation. Select the code that reflects laterality and specific digit involvement when that detail is available.

    Typical Clinical Scenarios

    • A neonate is delivered with an extra digit on the ulnar side of the right hand noted on initial newborn exam; no other anomalies are seen and the extra digit is well-formed and moveable. Parents seek pediatric orthopedic or plastic surgery consultation for evaluation and possible staged surgical removal for functional or cosmetic reasons. A congenital polydactyly diagnosis from this group is assigned to document the isolated postaxial hand malformation. Typical codes: Q69.2
    • A school-age child presents to the clinic with an extra rudimentary toe on the medial aspect of the left foot that has been present since birth but has caused recurrent irritation in shoes and occasional tripping. The family requests assessment for elective surgical correction to prevent ongoing problems and to improve gait mechanics. A congenital preaxial or postaxial lower-extremity extra digit code from this group is used to record the chronic congenital deformity. Typical codes: Q69.1, Q69.9
    • An adult arrives at the emergency department after a traumatic avulsion of an extra digit on the right hand following an industrial accident; the amputated supernumerary finger is partially devascularized and requires evaluation for replantation versus formal removal. The congenital nature of the extra digit is documented alongside the acute injury to guide surgical planning and coding of the underlying anomaly. Typical codes: Q69.0, Q69.2
