O03: ICD10 Code for Spontaneous abortion

O03 refers to Spontaneous abortion, encompassing abnormal pregnancies such as ectopic implantation, molar growths, failed pregnancy attempts, spontaneous loss, and complications arising from pregnancy terminations.

Symptoms

• Pelvic or abdominal pain – Seen especially in ectopic pregnancy (O00)
• Vaginal bleeding – A key symptom in spontaneous abortion (O03) and abnormal conceptions (O02)
• Severe nausea and vomiting – Associated with hydatidiform mole (O01)
• Signs of infection – After incomplete or complicated pregnancy terminations (O04, O08)
• Persistent pregnancy symptoms without viable embryo – Suggestive of molar pregnancy (O01)

Diagnosis

Diagnosis of Spontaneous abortion involves transvaginal ultrasound, serial beta-hCG measurements, pelvic examination, and sometimes surgical exploration (e.g., laparoscopy) to confirm ectopic implantation, molar growths, or retained products of conception.

ICD10 Code Usage

ICD10 code O03 is used by obstetricians, gynecologists, emergency physicians, and reproductive health providers to document early pregnancy complications, guide urgent or elective interventions, and ensure appropriate maternal follow-up care.

Related Codes

• O00 – Ectopic pregnancy
• O01 – Hydatidiform mole
• O02 – Other abnormal products of conception
• O04 – Complications following (induced) termination of pregnancy
• O07 – Failed attempted termination of pregnancy
• O08 – Complications following ectopic and molar pregnancy

FAQs

Q1: What is ICD10 code O03?
A: It refers to Spontaneous abortion, covering non-viable pregnancies, abnormal implantations, spontaneous losses, and post-pregnancy complications.

Q2: What is an ectopic pregnancy (O00)?
A: A pregnancy implanted outside the uterine cavity, often in a fallopian tube, posing a life-threatening risk if not treated promptly.

Q3: What is a hydatidiform mole (O01)?
A: A type of gestational trophoblastic disease where abnormal tissue grows inside the uterus instead of a normal embryo.

Q4: What causes spontaneous abortion (O03)?
A: Often due to chromosomal abnormalities, maternal infections, anatomical defects, or hormonal insufficiencies.

Q5: How are complications following pregnancy termination (O04, O07, O08) managed?
A: Management includes antibiotics for infections, surgical removal of retained tissue, supportive care, and counseling for physical and emotional recovery.

Conclusion

ICD10 code O03 provides essential documentation for the management of Spontaneous abortion, allowing clinicians to deliver timely interventions, monitor maternal health, and reduce complications related to abnormal or failed pregnancies.
