What This Code Means
O29.5X3 is the ICD-10-CM diagnosis code for other complications of spinal and epidural anesthesia during pregnancy, third trimester. Complications other than headache resulting from spinal or epidural anesthesia during the third trimester of pregnancy, such as nerve damage or infection. O29.5X3 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).
O29.5X3 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 most commonly used for complications during labor and delivery.
