Code Description

ICD-10 O02.1 is a billable code used to indicate a diagnosis of missed abortion.

Key Diagnostic Point:

Missed abortion, also known as a blighted ovum, occurs when a pregnancy is lost but the body does not recognize the loss and continues to exhibit signs of pregnancy. This condition is characterized by the absence of an embryo in the gestational sac, which can be identified through ultrasound. Patients may present with symptoms such as a lack of fetal heartbeat, spotting, or cramping, but many may not experience any symptoms at all. The diagnosis is typically made during a routine ultrasound when the absence of fetal development is noted. Management of missed abortion may involve expectant management, medical management with medications such as misoprostol, or surgical intervention such as dilation and curettage (D&C) to remove the retained products of conception. It is crucial for healthcare providers to offer emotional support and counseling to patients experiencing this type of pregnancy loss, as it can be a distressing experience.

  • Differentiating between missed abortion and other types of abortion (e.g., incomplete abortion)
  • Understanding the clinical implications of management options (medical vs. surgical)
  • Documentation of ultrasound findings and patient symptoms
  • Navigating emotional and psychological aspects of care

Audit Risk Factors

  • Inadequate documentation of ultrasound findings
  • Failure to document patient counseling and emotional support
  • Misclassification of missed abortion as complete or incomplete abortion
  • Lack of clarity in management decisions (medical vs. surgical)

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of missed abortion, improving the accuracy of data collection and analysis in obstetric care. It has also facilitated better tracking of pregnancy outcomes and management practices.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of missed abortion, improving the accuracy of data collection and analysis in obstetric care. It has also facilitated better tracking of pregnancy outcomes and management practices.

Reimbursement & Billing Impact

Frequently Asked Questions

What is the difference between missed abortion and incomplete abortion?

Missed abortion refers to a pregnancy loss where the embryo has not developed, and the body has not expelled the pregnancy tissue. Incomplete abortion, on the other hand, occurs when some but not all of the pregnancy tissue has been expelled, often requiring further medical intervention.
