CMS plans to take steps next year to improve the accuracy of its payments to hospitals for high-cost devices, though the agency does not promise as quick of a remedy as sought by manufacturers.
The so-called "charge compression fix" is included in the agency's fiscal year 2009 inpatient prospective payment system 1proposed rule, which was released April 14.
Charge compression, as described in a March 2007 CMS-commissioned report from research firm RTI International, relates to variations in hospital markup practices for certain products, and most notably affects devices and medical supplies.
Hospitals generally mark up charges for relatively inexpensive supplies at a higher rate than expensive devices. But CMS payment calculations, which are based on hospitals' cost reports, group all the products together to derive an overall payment for a procedure or diagnosis. Based on the math, the costs for services that include expensive products with low markups tend to be underestimated in the payment rates.
