Z36.0

Encounter for antenatal screening for chromosomal anomalies

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/12/2025

Code Description

ICD-10 Z36.0 is a billable code used to indicate a diagnosis of encounter for antenatal screening for chromosomal anomalies.

Key Diagnostic Point:

Z36.0 is used to document encounters for antenatal screening specifically aimed at identifying chromosomal anomalies such as Down syndrome, trisomy 18, and other genetic disorders. This screening is crucial for early detection and management of potential health issues in the fetus, allowing for informed decision-making by expectant parents. Factors influencing health status include maternal age, family history of genetic disorders, and access to healthcare services. Social determinants such as socioeconomic status, education level, and community resources can significantly impact a woman's ability to access prenatal care and screening services. Preventive care through early screening can lead to better health outcomes for both mother and child, emphasizing the importance of integrating social factors into healthcare planning and delivery.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Need for accurate documentation of screening results
  • Variability in screening protocols based on patient demographics
  • Potential for multiple encounters leading to confusion in coding
  • Integration of social determinants into clinical decision-making

Audit Risk Factors

  • Inadequate documentation of screening results
  • Failure to link Z36.0 with appropriate CPT codes for screening procedures
  • Misclassification of encounters as routine rather than screening-specific
  • Lack of clarity on the patient's risk factors for chromosomal anomalies

Specialty Focus

Medical Specialties

Primary Care

Documentation Requirements

Documentation must include details of the screening tests performed, results, and any follow-up plans.

Common Clinical Scenarios

Routine prenatal visits where screening for chromosomal anomalies is conducted.

Billing Considerations

Consideration of social determinants such as access to care and patient education on screening options.

Public Health

Documentation Requirements

Documentation should include population-level data on screening rates and outcomes.

Common Clinical Scenarios

Community health initiatives aimed at increasing awareness and access to prenatal screening.

Billing Considerations

Focus on tracking health disparities and improving access to screening services in underserved populations.

Coding Guidelines

Inclusion Criteria

Use Z36.0 When
  • Z codes are used when a patient encounters healthcare services for reasons other than a current illness or injury
  • 0 should be sequenced appropriately, often as a secondary code following a primary diagnosis related to pregnancy
  • Payer requirements may vary, so it's essential to verify coverage for screening services
