Code Description

ICD-10 O02.0 is a billable code used to indicate a diagnosis of blighted ovum and nonhydatidiform mole.

Key Diagnostic Point:

A blighted ovum, also known as an anembryonic pregnancy, occurs when a fertilized egg implants in the uterus but does not develop into an embryo. This condition is often identified during an early ultrasound when no fetal heartbeat is detected despite the presence of a gestational sac. A nonhydatidiform mole, on the other hand, is a type of gestational trophoblastic disease characterized by abnormal growth of trophoblastic tissue. Both conditions can lead to pregnancy loss, and their management may involve monitoring, medical management with medications such as misoprostol, or surgical intervention like dilation and curettage (D&C). The emotional and psychological impact of these conditions on patients is significant, necessitating sensitive communication and support from healthcare providers. Accurate coding is essential for proper management and follow-up care.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between blighted ovum and other types of pregnancy loss.
  • Understanding the implications of gestational trophoblastic disease.
  • Navigating the documentation requirements for missed and incomplete abortions.
  • Recognizing the need for follow-up care and monitoring post-diagnosis.

Audit Risk Factors

  • Inadequate documentation of ultrasound findings.
  • Failure to specify the type of pregnancy loss.
  • Incorrect coding of associated procedures (e.g., D&C).
  • Lack of follow-up documentation post-diagnosis.

Frequently Asked Questions

What is the difference between a blighted ovum and a missed abortion?

A blighted ovum occurs when a fertilized egg implants but does not develop into an embryo, while a missed abortion refers to a situation where the embryo has died but has not been expelled from the uterus. Both conditions can lead to pregnancy loss, but their management may differ.
