About coding Autistic psychopathy
The ICD-10-CM code for Autistic psychopathy is F84.5 (Asperger's syndrome).
Within F84 (pervasive developmental disorders), F84.5 is specifically for Asperger's syndrome. Related codes cover Autistic disorder (F84.0), Rett's syndrome (F84.2), other childhood disintegrative disorder (F84.3), other pervasive developmental disorders (F84.8) and pervasive developmental disorder, unspecified (F84.9).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 885 (Psychoses, relative weight 1.3901), in MDC 19 (Mental Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
