ICD-10-CM Changes for 2018
SMFM Coding CommitteeNewsletter Coding Tip – August 2017ICD-10-CM Changes for 2018With the adoption of the International Classification of Diseases, 10th edition, Clinical Modification (ICD-10-CM), Maternal Fetal Medicine (MFM) specialists lost the opportunity to be specific in assigning diagnoses for most of the common screening services. The only option available was Z36 Encounter for antenatal screening of the mother.
Effective for dates of service on or after October 1, 2017, the Z36 category has been subdivided to allow greater specificity. Unlike ICD-9-CM, these new ICD-10-CM codes define the purpose of the screening, rather than the screening modality.
The new codes are as follows:
Z36.0 Encounter for antenatal screening for chromosomal anomalies
Z36.1 …for raised alphafetoprotein level
Z36.2 …for other antenatal screening follow-up
Z36.3 …for malformation
Z36.4 …for fetal growth retardation
Z36.5 …for isoimmunization
Z36.8 …for other antenatal screening
Z36.81…for hydrops fetalis
Z36.82…for nuchal translucency
Z36.83…for congenital cardiac abnormalities
Z36.84…for fetal lung maturity
Z36.85…for Streptococcus B
Z36.86…for cervical length
Z36.87…for uncertain dates
Z36.88…for fetal macrosomia
Z36.89…for other specified antenatal screening
Z36.8A…for other genetic defects
