About coding fetal anomaly suspected condition
The ICD-10-CM code for fetal anomaly suspected condition is Z03.73 (Encounter for suspected fetal anomaly ruled out).
Within Z03.7 (encounter for suspected maternal and fetal conditions ruled out), Z03.73 is specifically for encounter for suspected fetal anomaly ruled out. Related codes cover suspected problem with amniotic cavity and membrane ruled out (Z03.71), suspected placental problem ruled out (Z03.72), suspected problem with fetal growth ruled out (Z03.74), suspected cervical shortening ruled out (Z03.75) and other suspected maternal and fetal conditions ruled out (Z03.79).
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.
