Incomplete spontaneous abortion without complication

This code represents a spontaneous abortion (miscarriage) where not all products of conception have been expelled from the uterus. The patient may present with persistent bleeding, cramping, or retained fetal or placental tissue following an initial spontaneous abortion event. There are no additional complications such as infection or hemorrhage noted.

Apply this code when documentation clearly indicates an incomplete spontaneous abortion without any specified complications. This is typically used when a patient presents after an initial miscarriage and ultrasound or clinical examination confirms retained products of conception. Documentation should explicitly state "incomplete" and absence of complications.

• Differentiate from "complete" spontaneous abortion (O03.9) where all products of conception have been expelled.
• Ensure no mention of infection, hemorrhage, or other complications, which would necessitate a more specific O03 subcategory.
• This code is often followed by a procedure code for evacuation of retained products of conception (e.g., D&C).
