In simple words: This code describes birth defects affecting the arms and hands. It covers situations where parts of an arm or hand are missing or not fully formed.

This ICD-10-CM code encompasses various congenital malformations resulting in incomplete development or absence of parts of the upper limb.The code includes conditions ranging from partial reductions (e.g., missing parts of the arm or hand) to complete absence of the entire limb.Further specification with additional codes (e.g., Q71.0, Q71.1, Q71.2) is necessary to describe the specific type and extent of the defect.

Example 1: A newborn is diagnosed with complete absence of the right arm (Q71.0)., A child is born with an absence of the forearm and hand on their left side, but their upper arm is present (Q71.2)., A patient presents with a congenital reduction defect where only a portion of their left forearm is formed (Q71 - additional specificity might be required).

Detailed clinical examination findings including description of the affected limb, images (radiographs, photographs), and genetic testing results (if applicable). Family history should be documented to assess hereditary factors.

** This code is not for use on maternal records.Excludes inborn errors of metabolism (E70-E88).Always confirm coding with the official ICD-10-CM coding manual and payer guidelines.
