What are the miscarriage ICD-10 codes?

If you're looking for miscarriage ICD codes, you might have some trouble because there are no ICD-10 codes that mention miscarriage in their names. However, that doesn't mean there aren't any codes for miscarriage.

Miscarriage is sometimes referred to as spontaneous abortion. Here are examples of specific codes you can use:

  • O02.1: Missed abortion: This ICD-10 code is meant to be used on a female patient confirmed to have a missed miscarriage, which means that their pregnancy has failed and the products of conception don't leave the body.
  • O03.4: Incomplete spontaneous abortion without complication: This code is used when a miscarriage is not fully completed. Incomplete abortion is when some tissue remains, but there are no additional complications present.
  • O03.9: Complete or unspecified spontaneous abortion without complication: This ICD-10 code is meant to be used on a female patient confirmed to have had a complete miscarriage or some other type of miscarriage that isn't incomplete or a missed abortion.
  • N96: Recurrent pregnancy loss: This ICD-10 code is meant to be used on a female patient confirmed to have recurrent miscarriages.

Please note that these ICD-10 codes above are for miscarriages only and do not include complications that can emerge due to miscarriages. For such complications, the following can be used:

  • O03.35: Other venous complications following incomplete spontaneous abortion: This code is used when a patient has venous issues, such as thrombosis, after an incomplete miscarriage.
  • O03.5: Genital tract and pelvic infection following complete or unspecified spontaneous abortion: This code applies when a miscarriage is complete or unspecified and is followed by an infection in the pelvic or genital area.
  • O03.80: Unspecified complication following complete or unspecified spontaneous abortion: This code is used when a patient has an unspecified complication after a complete or unspecified miscarriage.
  • O03.89: Complete or unspecified spontaneous abortion with other complications: Use this code when a miscarriage is complete or unspecified and is followed by specific, identified complications other than those classified elsewhere.
  • O04.80: (Induced) termination of pregnancy with unspecified complications: Use this code when a pregnancy was intentionally terminated, and the patient has complications that are not clearly identified.

Are these miscarriage ICD-10 codes billable?

Yes. All of the aforementioned related ICD-10 codes for miscarriage are valid and billable.

Clinical information about miscarriages

A miscarriage (sometimes referred to as spontaneous abortion) is the sudden end of a pregnancy sometime within the first twenty weeks of gestation. It is an occurrence beyond anyone's control and the result of the sudden halt in a fetus's growth in the womb.

It often occurs due to chromosomal imbalances in the fetus and abnormalities during the growth of a fertilized egg. Several factors are said to contribute to this problem, such as infections, excessive smoking and alcohol consumption, excessive use of recreational drugs, diabetes, heart disease, kidney disease, and thyroid disease, to mention a few.

The most common signs of miscarriage to look out for in a pregnant patient are cramps, abdominal pain, lower back pain, light to heavy vaginal bleeding, and passing of tissue and blood clots.

Synonyms include:

  • Complete miscarriage
  • Inevitable miscarriage
  • Fetal demise from miscarriage

Frequently asked questions

What is the definition of a miscarriage?

A miscarriage, also called a spontaneous abortion, is the loss of a pregnancy before 20 weeks of gestation. Pregnancy losses after the 20th week are called stillbirths.

What factors increase the risk of miscarriage in female patients?

Common risk factors include advanced maternal age, previous miscarriages, certain chronic conditions (like diabetes or thyroid disease), infections, uterine abnormalities, smoking, alcohol use, and high stress levels.

What happens to the body after a miscarriage?

After a miscarriage, the body typically experiences cramping and vaginal bleeding as it expels pregnancy tissue and begins to recover. Hormone levels gradually decrease, and physical symptoms such as breast tenderness and fatigue may occur, along with emotional responses that vary from person to person.
