Code Description

ICD-10 O03.9 is a billable code used to indicate a diagnosis of complete or unspecified spontaneous abortion without complication.

Key Diagnostic Point:

Spontaneous abortion, commonly referred to as miscarriage, is the loss of a pregnancy before the 20th week of gestation. The term 'complete' indicates that all products of conception have been expelled from the uterus, while 'unspecified' may refer to cases where the exact status of the pregnancy is not clearly documented. This condition can occur due to various factors, including chromosomal abnormalities, maternal health issues, or environmental factors. The emotional impact on patients can be significant, necessitating appropriate emotional support and counseling. It is crucial for healthcare providers to document the circumstances surrounding the spontaneous abortion, including any prior pregnancies, complications, and the patient's emotional state, to ensure comprehensive care and accurate coding.
