About coding cervical pregnancy
The ICD-10-CM code for cervical pregnancy is O00.41 (Cervical ectopic pregnancy without intrauterine pregnancy). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on O00.41.
Within O00.4, choose O00.41 (without intrauterine pregnancy) only when documentation doesn't support a more specific option: with intrauterine pregnancy (O00.42).
Use an additional code from category O08 to identify any associated complication.
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
