What This Code Means
O22.93 is the ICD-10-CM diagnosis code for venous complication in pregnancy, unspecified, third trimester. A blood vessel complication during the third trimester of pregnancy that is not further specified in type. O22.93 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).
O22.93 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 for unspecified venous complications occurring from week 28 through delivery.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for O22.93 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use for unspecified venous complications occurring from week 28 through delivery
- •Attempt to obtain clarification from the provider regarding the specific nature of the complication
