What This Code Means
O29.292 is the ICD-10-CM diagnosis code for other central nervous system complications of anesthesia during pregnancy, second trimester. A complication affecting the brain or spinal cord caused by anesthesia given during the second three months (weeks 13-26) of pregnancy. O29.292 sits in the ICD-10-CM chapter for pregnancy, childbirth and the puerperium (o00-o9a), within the section covering other maternal disorders predominantly related to pregnancy (o20-o29).
O29.292 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.
