Evolving Definitions of Autism and Impact on Eligibility for Developmental Disability Services: California Case Example.

Morrison et al. (2017) looked at one California boy who lost his state disability waiver after doctors updated the autism checklist. The team traced how new wording in the DSM made him ineligible overnight.

They used his story as a case to show that small rule changes can boot real people off service rolls.

The boy met the old autism rules but not the new ones, so California dropped his DD services. The authors warn that every state can hit families with the same surprise if criteria shift again.

Wong et al. (2009) earlier found no wide coding drift in California files; most label changes were honest, not cheats. Morrison et al. (2017) agree fraud is rare, yet show honest kids can still lose aid when rules tighten.

Williams et al. (2002) and Coo et al. (2008) proved that much of the autism boom came from kids switching over from intellectual-disability labels. The 2017 case flips that coin: the same switch can now roll backward, stripping supports.

Papazoglou et al. (2014) saw DSM-5 cut ID diagnoses by 9%. E et al. echo the warning for autism, showing the same shrinkage can happen there.

Before you reassess a client, pull your state’s waiver checklist side-by-side with the DSM-5. If the two don’t line up, flag the risk to the family and document why the person still needs hours. One extra page in the report can keep services in place.
