O00-O08Pregnancy with abortive outcome

ICD-10-CM codes O00-O08 cover pregnancy with abortive outcome, within pregnancy, childbirth and the puerperium. The block holds 116 codes across 7 categories, of which 94 are billable and 22 are header codes that cannot be submitted on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • continuing pregnancy in multiple gestation after abortion of one fetus or more (O31.1-, O31.3-)

What else to watch in O00-O08

  • 8 codes are laterality-specific. They come in left and right pairs, and the pair is mutually exclusive on a single site: coding both without a bilateral code is a contradiction a scrubber should catch before the payer does.
  • 64 codes are named in Medicare coverage policies. An LCD or NCD lists them as supporting medical necessity, or explicitly as not supporting it. Which applies depends on the MAC for your state.
