Z36Primary Range
Encounter for antenatal screening of mother
This range covers all encounters specifically for antenatal screening procedures.
Abnormal findings on antenatal screening of mother
This range is used when abnormal findings are detected during antenatal screening.
Weeks of gestation
This range is used to specify the gestational age in weeks, which is required with Z36 codes.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| Z36.0 | Encounter for antenatal screening for chromosomal anomalies | Use for routine antenatal screening for chromosomal anomalies. |
|
| O28.1 | Abnormal biochemical finding on antenatal screening | Use when biochemical abnormalities are found during antenatal screening. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Use when biochemical abnormalities are found during antenatal screening.
Applicable To
- Elevated AFP levels
Excludes
- Z36.1 - Encounter for antenatal screening for raised AFP level
Clinical Validation Requirements

Coding Notes
Ensure abnormal findings are clearly documented.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Pregnancy Screening to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code Z36.0.
Impact
Clinical: Misinterpretation of screening results., Regulatory: Non-compliance with coding guidelines., Financial: Potential claim denials.
Mitigation Strategy
Always document gestational age with Z3A codes.
Impact
Reimbursement: Incorrect DRG assignment leading to potential underpayment., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use O28 codes for abnormal findings.
Impact
Failure to document gestational age can lead to audit findings.
Mitigation Strategy
Implement mandatory fields for gestational age in EHR systems.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
