Specific Coding Applicable to Encounter for antenatal screening of mother

Non-specific codes like Z36 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for encounter for antenatal screening of mother:

  • Use Z36.0 for Encounter for antenatal screening for chromosomal anomalies - BILLABLE CODE

  • Use Z36.1 for Encounter for antenatal screening for raised alphafetoprotein level - BILLABLE CODE

  • Use Z36.2 for Encounter for other antenatal screening follow-up - BILLABLE CODE

  • Use Z36.3 for Encounter for antenatal screening for malformations - BILLABLE CODE

  • Use Z36.4 for Encounter for antenatal screening for fetal growth retardation - BILLABLE CODE

  • Use Z36.5 for Encounter for antenatal screening for isoimmunization - BILLABLE CODE

  • Z36.8 for Encounter for other antenatal screening - NON-BILLABLE CODE

Clinical Classification

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

Antenatal screening

CCSR Code: PRG001

Inpatient Default: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.

Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

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.
  • Encounter for placental sample (taken vaginally)
  • Screening is the testing for disease or disease precursors in asymptomatic individuals so that early detection and treatment can be provided for those who test positive for the disease.

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.
  • diagnostic examination- code to sign or symptom
  • encounter for suspected maternal and fetal conditions ruled out Z03.7
  • suspected fetal condition affecting management of pregnancy - code to condition in Chapter 15

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.
  • abnormal findings on antenatal screening of mother O28
  • genetic counseling and testing Z31.43 Z31.5
  • routine prenatal care Z34

Patient Education


Prenatal Testing

What is prenatal testing?

Prenatal testing provides information about the health of your fetus before the baby is born. Some routine tests during pregnancy also check your health. The prenatal test may use a sample of your blood, urine or fluid from your vagina, cervix, or rectum.

Since some health conditions can be treated before your baby is born, it's important to find them early. But even if they cannot be treated, it can still be helpful to know about the problem early on. This gives you time to learn about the condition and prepare for any challenges you may face after the baby is born.

What is prenatal testing used to diagnose?

At your first prenatal visit, your health care provider will test for various conditions, including problems with your blood, signs of infections, and whether you are immune to rubella (German measles) and chickenpox.

Throughout your pregnancy, your provider may recommend additional tests as well. Some tests are suggested for all women, such as screenings for gestational diabetes, Down syndrome, and HIV.

Your provider might offer other tests based on your:

  • Age
  • Personal or family medical history
  • Ethnic background
  • Results of routine tests

What are the two types of prenatal tests?

There are two types of tests:

  • Screening tests check if you or your fetus may have certain health issues. They look at risk but do not diagnose problems. If your screening test result is abnormal, it does not mean that there is a problem. It means that more information is needed. Your provider can explain what the test results mean and possible next steps. You may need diagnostic testing.
  • Diagnostic tests help determine whether you or your fetus have a certain health problem.

It is your choice whether to get prenatal tests. You and your provider can talk about the risks and benefits of the tests, as well as the type of information they can give you. Then you can decide which ones are right for you.
