O29.029 ICD-10-CM Code: Pressure collapse of lung due to anesthesia during pregnancy, unspecified trimester

O29.029 is the ICD-10-CM diagnosis code for pressure collapse of lung due to anesthesia during pregnancy, unspecified trimester. Collapse of lung tissue due to pressure changes from anesthesia during pregnancy when the specific trimester is not documented or identified. O29.029 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).

O29.029 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.

Query the provider for trimester information before assigning this unspecified code.
