Common billing errors — Psychiatric charges

Psychiatric drug billing frequently shows charges above the benchmark of $1.67 average NADAC cost, with markups ranging from 200-800% common across hospital systems. Duplicate billing occurs when patients receive both brand-name and generic versions of the same medication class, particularly with antidepressants like sertraline/Zoloft or antipsychotics such as quetiapine/Seroquel, creating potential differences of $50-200 per duplicate entry. Generic substitution errors appear when hospitals bill for brand-name psychiatric medications while dispensing generics, especially problematic with mood stabilizers and anxiety medications where the cost differential can exceed $100 per dose. Prior authorization requirements for newer psychiatric drugs sometimes result in billing for rejected medications that were never properly dispensed, and therapeutic duplications within the same drug class—such as multiple SSRIs or benzodiazepines—frequently appear on itemized statements without clear clinical justification, representing significant potential differences when compared to standard treatment protocols.
