What This Code Means
Q71.893 is the ICD-10-CM diagnosis code for other reduction defects of upper limb, bilateral. A birth defect affecting both arms where they are incompletely formed or have missing parts that are not fully classified into other specific categories. Q71.893 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).
Q71.893 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 indicates bilateral involvement; confirm documentation specifies both upper limbs are affected.

Coding Tips
- •This code indicates bilateral involvement; confirm documentation specifies both upper limbs are affected
