The chargemaster is both a direct and indirect target of compliance and thus various types of audits. Hospitals should periodically take the time to examine their chargemasters from a compliance perspective. This means examining and review various CDM policies and procedures (P&Ps), which must dovetail to coding P&Ps, as well as billing P&Ps. Issues such as transparent pricing, proper use of revenue codes, cost report interface, coding interface, billing interface, supply categorization, etc. must all be considered. A systematic process for auditing the chargemaster relative to this host of compliance issues is discussed.
