Outpatient apheresis billing: A photopheresis model shows that hospital price transparency data remain difficult to...

The US health care payment system is complex and difficult to interpret. Although federal regulations require that more data, in the form of charges and negotiated rates, be made available, compliance remains variable. We review chargemaster and negotiated rate values for extracorporeal photopheresis (ECP) to assess this variability. We sought to determine the availability of chargemaster and negotiated rates for health care consumers and to assess compliance and pricing among institutions using ECP as a model for apheresis billing.

We obtained ECP chargemaster data and negotiated rates from 20 institutions. We analyzed the availability of ECP chargemaster data and compared values with a previously published historic cohort. We evaluated the availability of negotiated rates and determined relative reimbursement using charge to reimbursement ratios. We determined calculated fines for hospitals based on bed size.

Chargemaster availability increased from 2019 to 2022, though only 65% (13/20) of hospitals had both chargemaster and negotiated rate data. Chargemaster prices increased significantly from 2019 to 2022 (range, $3,586.83-$34,043.00). We reviewed 1,191 negotiated rates, with institutions averaging 93.6 different rates (SD, 189.5). Negotiated rates were variable, ranging from $3,586.83 to $34,043.00 per procedure. Reimbursement was higher among private insurers compared with reported Centers for Medicare & Medicaid Services negotiated rates. Of the 35% (7/20) that lacked chargemaster and negotiated rates, institutions faced an average annual fine of $1,430,800.

Despite recent financial penalties, ECP pricing data are often unavailable or inadequate. Current available resources are unlikely to benefit the average health care consumer who requires ECP.
