What This Code Means
Q76.2 is the ICD-10-CM diagnosis code for congenital spondylolisthesis. A birth defect where one vertebra in the spine is positioned forward over the vertebra below it due to abnormal bone development. Q76.2 sits in the ICD-10-CM chapter for congenital malformations, deformations and chromosomal abnormalities (q00-qa0), within the section covering congenital malformations and deformations of the musculoskeletal system (q65-q79).
Q76.2 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.
Differentiate congenital spondylolisthesis from acquired spondylolisthesis (M43.1x) which develops later in life.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Q76.2 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Differentiate congenital spondylolisthesis from acquired spondylolisthesis (M43.1x) which develops later in life
- •Document the grade of slippage if documented in imaging reports for clinical completeness
