What This Code Means
Q71.819 is the ICD-10-CM diagnosis code for congenital shortening of unspecified upper limb. A congenital condition where an upper limb is abnormally short from birth, but the specific side (right, left, or both) is not documented. Q71.819 sits in the ICD-10-CM chapter for congenital malformations, deformations, chromosomal abnormalities, and genetic disorders (q00-qa0), within the section covering congenital malformations and deformations of the musculoskeletal system (q65-q79).
Q71.819 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Use this code only when laterality is not specified in the documentation.
