What This Code Means
Q71.812 is the ICD-10-CM diagnosis code for congenital shortening of left upper limb. A congenital condition where the left upper limb (arm) is abnormally short from birth due to underdevelopment. Q71.812 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).
Q71.812 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.
This code is specific to the left side; use Q71.811 for right side or Q71.813 for bilateral.
