Z36.84

Encounter for antenatal screening for fetal lung maturity

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

Code Description

ICD-10 Z36.84 is a billable code used to indicate a diagnosis of encounter for antenatal screening for fetal lung maturity.

Key Diagnostic Point:

Z36.84 is used to indicate an encounter for antenatal screening specifically aimed at assessing fetal lung maturity. This screening is crucial for pregnant individuals, particularly those at risk for preterm delivery, as it helps determine the readiness of the fetus's lungs for breathing air outside the womb. Factors influencing health status include maternal age, socioeconomic status, access to prenatal care, and existing health conditions. Social determinants such as education level, income, and community resources can significantly impact the frequency and quality of prenatal visits. Preventive care through regular screenings can lead to early interventions, improving outcomes for both the mother and the infant. This code is essential in documenting the proactive measures taken to ensure fetal health and readiness for delivery, reflecting the importance of comprehensive prenatal care in reducing neonatal complications.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Need for accurate documentation of gestational age and risk factors.
  • Variability in screening protocols across different healthcare settings.
  • Potential for overlapping codes related to prenatal care.
  • Requirement for clear linkage between the encounter and the screening purpose.

Audit Risk Factors

  • Inadequate documentation of the reason for screening.
  • Failure to link the Z code with appropriate CPT codes for the screening procedure.
  • Misclassification of the encounter type (preventive vs. diagnostic).
  • Lack of evidence supporting the necessity of the screening in the medical record.

Specialty Focus

Documentation Requirements

Documentation should include details of the patient's prenatal history, risk factors, and the specific purpose of the screening.

Common Clinical Scenarios

Routine prenatal visits where fetal lung maturity is assessed, especially in high-risk pregnancies.

Billing Considerations

Consideration of social determinants such as access to care, education, and support systems that may affect prenatal health.

Public Health

Documentation Requirements

Population-level data collection and documentation of screening outcomes for public health surveillance.

Common Clinical Scenarios

Community health initiatives aimed at improving maternal and infant health outcomes through targeted screenings.

Billing Considerations

Focus on health disparities and access to prenatal care in underserved populations.

Coding Guidelines

Inclusion Criteria

Use Z36.84 When
  • Z codes are used to indicate encounters for circumstances other than a disease or injury
  • When coding Z36
  • 84, it should be sequenced appropriately based on the primary reason for the encounter
  • Payer requirements may vary, so it is essential to verify coverage for preventive screenings

Exclusion Criteria

Clinical Scenario

Used during the encounter for fetal lung maturity screening to assess fetal development.

Documentation Requirements

Documentation must include the reason for the ultrasound and findings related to fetal lung maturity.

Specialty Considerations

Primary care providers should ensure that all relevant clinical information is captured to support the use of Z36.84.
