Range Overview
high priority
The ICD-10 code range O30-O48 pertains to maternal care related to the fetus and amniotic cavity and potential delivery problems. These codes are used to document conditions and complications that may arise during pregnancy, affecting either the mother or the fetus. They cover a wide array of issues, including multiple gestation, maternal care for abnormalities of the fetus, and complications of the amniotic cavity.
Key Usage Points:
- •Use these codes to document conditions and complications that arise during pregnancy.
- •These codes cover multiple gestation, maternal care for fetal abnormalities, and complications of the amniotic cavity.
- •Always code to the highest level of specificity.
- •Use additional codes from other chapters to identify any associated maternal conditions.
- •Follow the ICD-10 guidelines for coding pregnancy, childbirth, and the puerperium.
Coding Guidelines
When to Use:
- ✓When documenting multiple gestation pregnancies.
- ✓When documenting maternal care for known or suspected fetal abnormalities.
- ✓When documenting complications related to the amniotic cavity.
- ✓When documenting potential delivery problems due to maternal pelvic and perineal conditions.
- ✓When documenting potential delivery problems due to fetal conditions.
When NOT to Use:
- ✗When the pregnancy is uncomplicated.
- ✗When the condition does not affect the current pregnancy, childbirth, or the puerperium.
- ✗When the condition is related to the mother but does not affect the fetus or amniotic cavity.
- ✗When the condition is a routine prenatal visit.
Code Exclusions
Always verify exclusions with the latest ICD-10-CM Official Guidelines for Coding and Reporting.
Documentation Requirements
Accurate documentation is crucial for coding within this range. It should include detailed information about the pregnancy, any complications or conditions affecting the mother or fetus, and the impact of these conditions on the pregnancy or potential delivery.
Clinical Information:
- •Detailed description of the pregnancy (e.g., gestational age, number of fetuses).
- •Detailed description of any complications or conditions.
- •Impact of the condition on the pregnancy or potential delivery.
- •Any treatment provided or planned.
Supporting Evidence:
- •Medical history.
- •Clinical findings.
- •Diagnostic test results.
- •Treatment plans.
Good Documentation Example:
Patient is 28 weeks pregnant with twins. Ultrasound shows Twin B is breech. Plan for cesarean section.
Poor Documentation Example:
Twin pregnancy.
Common Documentation Errors:
- âš Not coding to the highest level of specificity.
- âš Not documenting the impact of the condition on the pregnancy or potential delivery.
- âš Not using additional codes to identify any associated maternal conditions.

Complexity Rating
Coding within this range requires a good understanding of obstetric medical terminology and the ability to interpret detailed clinical documentation. Coders must also be familiar with the ICD-10 coding guidelines for pregnancy, childbirth, and the puerperium, and be able to code to the highest level of specificity. The need to use additional codes to fully capture the patient's clinical picture adds to the complexity.
Key Factors:
- â–¸Understanding of obstetric medical terminology.
- â–¸Ability to interpret detailed clinical documentation.
- â–¸Knowledge of ICD-10 coding guidelines for pregnancy, childbirth, and the puerperium.
- â–¸Ability to code to the highest level of specificity.
- â–¸Understanding of when to use additional codes.
Specialty Focus
