About Z36.83
Z36.83 is the ICD-10-CM diagnosis code for encounter for fetal screening for congenital cardiac abnormalities. It belongs to category Z36 (encounter for antenatal screening of mother), block Z30-Z39 (persons encountering health services in circumstances related to reproduction) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within Z36.8 (encounter for other antenatal screening), Z36.83 is specifically for encounter for fetal screening for congenital cardiac abnormalities. Related codes cover antenatal screening for hydrops fetalis (Z36.81), antenatal screening for nuchal translucency (Z36.82), antenatal screening for fetal lung maturity (Z36.84), antenatal screening for Streptococcus B (Z36.85), antenatal screening for cervical length (Z36.86), antenatal screening for uncertain dates (Z36.87), antenatal screening for fetal macrosomia (Z36.88), other specified antenatal screening (Z36.89) and 1 more.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
The Medicare Code Editor treats this as a maternity diagnosis, expected only for patients age 9 through 64.
It is on the CMS list of diagnoses consistent only with female patients (the sex-conflict edit itself was retired in FY2025).
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It was added in FY2018, effective October 1, 2017.
Before ICD-10, this condition was coded in ICD-9-CM as V28.89 (other specified antenatal screening).
