Check the procedure code together with revenue code, date, units, modifiers when applicable, and charge.
Procedure-code selection is a coding task.

Revenue and procedure codes answer different questions

The revenue code categorizes the institutional service area or type; the HCPCS or procedure code can provide more specific service detail. Neither should be chosen merely to make the other look plausible.

Review line-level companions

Check the procedure code together with revenue code, date, units, modifiers when applicable, and charge. A copied procedure code with a new revenue line can create an inconsistent claim.

Use current coding sources

Procedure-code selection is a coding task. Use current official or licensed code-set resources and payer instructions rather than relying on an old claim as the authority.

Institutional-claim review

Review the HCPCS/procedure field together with the revenue code, service date, units, and charge.
Use current code sets for the date of service and apply payer-specific modifier rules.
Do not assume every revenue line requires the same type of procedure-code entry.

Sources and verification

Use the CMS institutional-claim sources below for current CMS-1450/UB-04 guidance, then apply the payer’s rules for the facility claim.
