Billable / specific codeICD-10-CM

O29.8X9 is a billable, specific ICD-10-CM code for other complications of anesthesia during pregnancy, unspecified trimester. It is valid for submission on a claim.

Excludes2 inherited from the categories above O29.8X9

Also inherited, and the opposite of Excludes1: these conditions are not part of O29.8X9, but a patient can have both, so you may code both.

Written on O29 Complications of anesthesia during pregnancy

  • complications of anesthesia during labor and delivery (O74.-)
  • complications of anesthesia during the puerperium (O89.-)

Other codes that can never be billed with O29.8X9

These codes carry an Excludes1 note pointing at O29.8X9. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O29.8X9 alone.

  • T41Poisoning by, adverse effect of and underdosing of anesthetics and therapeutic gases
  • T88.2Shock due to anesthesia
  • T88.2XXAShock due to anesthesia, initial encounter
  • T88.2XXDShock due to anesthesia, subsequent encounter
  • T88.2XXSShock due to anesthesia, sequela

Risk adjustment

O29.8X9 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.

Code history

O29.8X9 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
