What matters most
- When a line uses a date range, confirm that the range is permitted for the service and payer.
- Compare dates with procedure coding, place of service, units, authorization period, and documentation.
- Use the current NUCC 1500 Reference Instruction Manual for standardized field guidance and then apply the payer's current requirements.
From and to dates
When a line uses a date range, confirm that the range is permitted for the service and payer. Do not use a multi-day span merely to summarize several separate encounters.
Cross-check the line
Compare dates with procedure coding, place of service, units, authorization period, and documentation. A valid calendar date can still be wrong for the service line.
Template risk
Dates are highly claim-specific. Clear prior service dates when copying a claim template.
Before you release the service line
- Compare the from/to date in Item 24A with the encounter or treatment record.
- Make sure the date range makes sense with the procedure code, units, place of service, and authorization period.
- Clear old dates when a service line is copied from a template or earlier claim.
A small date error can affect several fields
When a date of service changes, also review any authorization period, procedure coding, place of service, units, and documentation tied to that line. This is a good reason to edit claims from the source record rather than correcting only the printed date. A service-line review that starts with the encounter date can catch mismatches before the claim reaches the payer.
Sources and verification
Use the NUCC/CMS sources below to confirm current CMS-1500 instructions, then apply the payer’s rules for the specific professional claim.
