    ICD-10-CM Code For Other Congenital Malformations Of Limb(S): Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group Q74 includes congenital malformations of the limbs not classified elsewhere, such as hypoplasia, duplication, or other structural limb anomalies. These ICD-10-CM diagnosis codes are used to document clinical presentations of limb deformity, functional impairment, and related developmental or surgical considerations. Accurate coding within the ICD-10-CM Q74 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM Q74: Other Congenital Malformations Of Limb(S) Overview

    This group represents congenital malformations affecting the limbs that are not classified elsewhere, including structural anomalies of arms, hands, legs, or feet. These conditions involve the musculoskeletal system and can impact function, development, and need for surgical or prosthetic management. Accurate coding matters for clinical records and reimbursement because it supports appropriate documentation of severity and service necessity.

    Typical Clinical Scenarios

    • Infant born with a shortened right forearm and absent radius identified on newborn exam and confirmed by radiographs after referral from the delivery nursery; the family seeks evaluation for orthopedic management and prosthetic planning, and the congenital limb deficiency is coded from this group. Typical codes: Q74.2, Q74.9
    • Child with congenital clubfoot noted at routine pediatric visit because of persistent foot inversion and stiffness causing difficulty with shoe wear and ambulation; referral for serial casting or surgery is initiated and the congenital malformation of the foot is documented using a specific code from this group. Typical codes: Q74.0, Q74.9
    • Adult with long-standing congenital hand malformation presenting for repair of thumb hypoplasia that has resulted in decreased function and secondary osteoarthritis; preoperative assessment documents the congenital etiology of the limb deformity as the underlying diagnosis. Typical codes: Q74.1, Q74.9
