Code first

The underlying condition must be sequenced before this code.

  • to specify reason for planned cesarean section such as:
  • cephalopelvic disproportion (normally formed fetus) (O33.9)
  • previous cesarean delivery (O34.21-)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Delivery by (planned) cesarean section occurring after 37 completed weeks of gestation but before 39 completed weeks gestation due to (spontaneous) onset of labor

Risk adjustment

O75.82 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
