Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Includes

Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
  • the listed conditions in the fetus as a reason for hospitalization or other obstetric care of the mother, or for termination of pregnancy

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • encounter for suspected maternal and fetal conditions ruled out Z03.7
  • placental transfusion syndromes O43.0

Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
  • labor and delivery complicated by fetal stress O77

7th Character Note

7th Character Note
Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
  • One of the following 7th characters is to be assigned to each code under category O36. 7th character 0 is for single gestations and multiple gestations where the fetus is unspecified. 7th characters 1 through 9 are for cases of multiple gestations to identify the fetus for which the code applies. The appropriate code from category O30

7th Character

7th Character
Indicates that a seventh character is to be assigned to codes in a subcategory.
  • 0 - not applicable or unspecified
  • 1 - fetus 1
  • 2 - fetus 2
  • 3 - fetus 3
  • 4 - fetus 4
  • 5 - fetus 5
  • 9 - other fetus

Patient Education


Health Problems in Pregnancy

Every pregnancy has some risk of problems, but there are certain conditions and health issues that can raise that risk, such as:

  • A health condition you had before you got pregnant
  • A health condition you develop during pregnancy
  • A pregnancy with more than one baby
  • A health problem that happened during a previous pregnancy and could happen again
  • Substance use during pregnancy
  • Being over age 35

Any of these can affect your health, the health of your baby, or both.

If you have a chronic condition, you should talk to your health care provider about how to minimize your risk before you get pregnant. Once you are pregnant, you may need a health care team to monitor your pregnancy. Some common conditions that can complicate a pregnancy include:

  • High blood pressure
  • Kidney problems
  • Autoimmune diseases
  • Obesity
  • HIV
  • Cancer
  • Infections

Other conditions that may make pregnancy risky can develop during pregnancy - for example, gestational diabetes and Rh incompatibility. Good prenatal care can help detect and treat them.

Some symptoms, such as nausea, back pain, and fatigue, are common during pregnancy. Sometimes it is hard to know what is normal. Call your health care provider if something is bothering or worrying you.
