About coding autism screening
The ICD-10-CM code for autism screening is Z13.41 (Encounter for autism screening).
Within Z13.4 (encounter for screening for certain developmental disorders in childhood), Z13.41 is specifically for encounter for autism screening. Related codes cover screening for unspecified developmental delays (Z13.40), screening for global developmental delays (milestones) (Z13.42) and screening for other developmental delays (Z13.49).
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.
