What This Code Means
O29.129 is the ICD-10-CM diagnosis code for cardiac failure due to anesthesia during pregnancy, unspecified trimester. Heart failure caused by anesthesia during pregnancy when the specific trimester is not documented or specified. O29.129 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).
O29.129 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 trimester information is unavailable or unclear in the medical record.
