What Is the Chargemaster
The Charge Description Master, commonly called the chargemaster or CDM, is the master file containing every billable item, service, and procedure an organization offers, along with associated charge codes, CPT or HCPCS codes, revenue codes, and prices. The chargemaster serves as the foundation for generating patient bills and claims.
Chargemaster Structure
Each chargemaster line item typically includes a description of the item or service, a department or cost center, an internal charge code, the applicable CPT or HCPCS code, a revenue code, and the associated price. Consistency between the CPT and revenue code pairing is critical, since mismatches can cause claim rejections or compliance concerns.
Chargemaster Maintenance
Chargemaster maintenance is an ongoing, cross-functional responsibility involving HIM, finance, compliance, and clinical departments. Annual updates are required to reflect new CPT and HCPCS codes released each January, along with quarterly updates for new or revised codes. A chargemaster committee often oversees additions, deletions, and pricing changes to ensure accuracy and compliance.
Common Maintenance Activities
- Updating CPT and HCPCS codes for annual and quarterly code set changes
- Reviewing revenue code to CPT code crosswalks for accuracy
- Removing obsolete or discontinued services
- Validating National Correct Coding Initiative edits
- Auditing high-dollar or high-volume charge lines for accuracy
Pricing Strategies
Pricing strategy involves balancing competitive market rates, cost recovery, and payer contract terms. Many organizations use a charge-to-cost ratio approach or benchmark pricing against regional competitors. Price transparency regulations now require hospitals to publish standard charges, including payer-specific negotiated rates, increasing scrutiny on chargemaster accuracy and consistency.
Charge Capture
Charge capture refers to the process of recording services rendered so they can be billed. Missed charge capture, whether from manual entry errors, workflow gaps, or system interface failures, directly reduces revenue. Charge capture audits compare clinical documentation against billed charges to identify under-billing or over-billing.
Revenue Integrity
Revenue integrity programs combine chargemaster oversight, charge capture auditing, coding compliance, and denial management into a coordinated function that protects both revenue and compliance. HIM professionals contribute clinical documentation and coding expertise that is essential to a well-functioning revenue integrity program.
