Range Overview
high priority
The ICD-10 category O00-O08 covers codes related to pregnancy with abortive outcome. These codes are used to document cases where a pregnancy ends prematurely, either naturally (miscarriage) or artificially (abortion). The range includes specific codes for ectopic pregnancies, molar pregnancies, other abnormal products of conception, and complications following an abortive outcome.
Key Usage Points:
- •Always code for each individual condition related to the abortive outcome.
- •Use additional codes to identify any associated complications.
- •The trimester of pregnancy should be specified if known.
- •For artificial abortions, specify whether it was performed due to medical reasons or personal choice.
- •When coding for ectopic or molar pregnancies, specify the location or type.
Coding Guidelines
When to Use:
- ✓When a pregnancy ends in miscarriage.
- ✓When an abortion is performed due to medical reasons.
- ✓In cases of ectopic or molar pregnancies.
- ✓When complications arise following an abortive outcome.
- ✓When a pregnancy is terminated due to personal choice.
When NOT to Use:
- ✗When a pregnancy results in a live birth.
- ✗When complications are unrelated to the abortive outcome.
- ✗When coding for prenatal visits or routine pregnancy care.
- ✗When the patient is not pregnant.
- ✗When the abortive outcome is suspected but not confirmed.
Code Exclusions
Always verify the patient's pregnancy status and the nature of the abortive outcome before coding.
Documentation Requirements
Documentation for codes in the O00-O08 range should clearly specify the type of abortive outcome, any associated complications, and the trimester of pregnancy if known. The reason for any artificial abortion should also be documented.
Clinical Information:
- •Type of abortive outcome
- •Any associated complications
- •Trimester of pregnancy
- •Reason for artificial abortion
- •Location or type of ectopic or molar pregnancy
Supporting Evidence:
- •Medical records
- •Physician's notes
- •Laboratory test results
- •Ultrasound reports
Good Documentation Example:
Patient presented with severe abdominal pain and vaginal bleeding. Ultrasound confirmed a ruptured ectopic pregnancy in the left fallopian tube. Emergency surgery was performed to remove the ectopic pregnancy.
Poor Documentation Example:
Patient had a miscarriage.
Common Documentation Errors:
- âš Not specifying the trimester of pregnancy
- âš Not documenting the reason for an artificial abortion
- âš Not providing enough detail on the type or location of an ectopic or molar pregnancy
- âš Not coding for each individual condition

Complexity Rating
Coding for pregnancy with abortive outcome can be complex due to the need to accurately identify and code for the specific type of abortive outcome and any associated complications. The trimester of pregnancy and the reason for an artificial abortion must also be specified. Additionally, ectopic and molar pregnancies require further detail on the location or type.
Key Factors:
- â–¸Determining the specific type of abortive outcome
- â–¸Identifying and coding for any associated complications
- â–¸Specifying the trimester of pregnancy
- â–¸Determining the reason for an artificial abortion
- â–¸Identifying the location or type of an ectopic or molar pregnancy
Specialty Focus
Codes in the O00-O08 range are most commonly used by obstetricians and gynecologists. They may also be used by emergency medicine physicians and general practitioners.

Clinical Scenarios:
- • A patient presents with a confirmed miscarriage at 10 weeks gestation.
- • A patient undergoes a medically necessary abortion due to severe preeclampsia.
- • A patient presents with severe abdominal pain and is diagnosed with a ruptured ectopic pregnancy.
- • A patient presents with heavy bleeding and cramping following a self-induced abortion.
- • A patient is diagnosed with a molar pregnancy during a routine ultrasound.

Frequently Asked Questions
How do I code for a miscarriage?
Use the appropriate code from the O03 subcategory to document a miscarriage. Specify the trimester of pregnancy if known.
How do I code for an ectopic pregnancy?
Use the appropriate code from the O00 subcategory to document an ectopic pregnancy. Specify the location of the ectopic pregnancy if known.
