    ICD-10-CM Code For Reduction Defects Of Upper Limb: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group Q71 includes congenital reduction defects of the upper limb such as transverse and longitudinal deficiencies affecting the arm, forearm, wrist, or hand. These ICD-10-CM diagnosis codes are used to document congenital limb deficiencies, capturing anatomical level of involvement and laterality which reflect clinical complexity. Accurate coding within the ICD-10-CM Q71 group supports proper claim adjudication and complete clinical documentation.

    ICD-10-CM Q71: Reduction Defects Of Upper Limb Overview

    The ICD-10-CM Q71 group covers congenital reduction defects of the upper limb, including transverse and longitudinal deficiencies affecting the arm, forearm, wrist, or hand. These diagnoses represent congenital malformations of the musculoskeletal system that can range from partial absence to complete absence of structures. Accurate coding ensures complete clinical documentation and supports appropriate reimbursement for services related to diagnosis, prosthetic evaluation, and surgical or rehabilitative care.

    Typical Clinical Scenarios

    • A newborn evaluated in the newborn nursery with unilateral absence of the forearm and hand observed on physical exam; parents report no family history and delivery was otherwise uncomplicated. The infant is referred to pediatrics and orthopedics for assessment of limb deficiency and prosthetic/rehabilitation planning, and a congenital longitudinal reduction defect of the upper limb is coded. Typical codes: Q71.01, Q71.11
    • A 6-year-old child with limited elbow joint development and shortened humerus presenting for ongoing orthopedic management and physical therapy; the child has impairment of function but no acute illness. Because this is a chronic congenital reduction defect affecting the arm segment, the visit is coded to reflect a congenital reduction deformity of the upper limb for follow-up, growth monitoring, and surgical planning. Typical codes: Q71.21, Q71.31
    • An adult with a history of congenital partial absence of the hand presents to the emergency department after a traumatic wound to the residual limb with infection; treatment includes wound care and coordination with prosthetics. The coding captures the congenital reduction defect as a comorbidity impacting management of the acute traumatic/infectious complication. Typical codes: Q71.51, Q71.811
