Incomplete spontaneous abortion with other complications

This code signifies a spontaneous abortion (miscarriage) that has not fully completed, meaning some products of conception remain within the uterus, and is accompanied by additional medical complications. These complications are not specified as hemorrhage, infection, or genitourinary tract damage, but rather other adverse events.

Apply this code when documentation indicates an incomplete miscarriage with an associated complication not covered by more specific O03 subcategories (e.g., O03.0 for hemorrhage, O03.1 for infection). Examples include cases with retained products of conception and conditions like uterine atony, coagulopathy, or other systemic issues directly resulting from the incomplete abortion.

• Ensure documentation clearly specifies both the incomplete nature of the abortion and the "other" complication.
• Do not use if the complication is explicitly hemorrhage (O03.0), infection (O03.1), or genitourinary tract damage (O03.2).
• Always sequence this code as the principal diagnosis when it is the reason for the encounter, followed by codes for any specific complications if applicable and not already covered by a more specific O03 subcategory.
