Core claim data groups
| Data group | Examples of what billing verifies |
|---|---|
| Patient / subscriber | Name, date of birth, member ID, relationship and address when required. |
| Provider | Billing provider, rendering provider, identifiers and service location. |
| Encounter | Date of service, place of service and applicable referral/authorization information. |
| Clinical coding | Supported diagnosis codes, procedure/service codes, modifiers and diagnosis pointers/linkage. |
| Financial | Charges, units and other payer-required billing data. |
Diagnosis linkage
Professional claims connect service lines to the diagnosis information that helps explain why the service was provided. The linkage must reflect the documented and coded encounter; billing staff should not create unsupported diagnosis relationships simply to pass an edit.
Frequent charge-entry problems
- Wrong patient or insurance selected.
- Incorrect date of service.
- Rendering provider or place of service omitted.
- Modifier or units missing where required.
- Diagnosis information not linked correctly to the service line.
- Duplicate charge entered.
- Authorization or referral information omitted when the payer requires it.
Pre-submission sequence
- Confirm patient and active coverage.
- Confirm provider and service location.
- Compare charge information with the coding/documentation workflow.
- Review dates, codes, modifiers, units and diagnosis linkage.
- Run claim edits and resolve supported corrections.

Yes. It can affect eligibility, coding validity, authorization and payer processing.
Should billing create a diagnosis link that is not supported by the encounter?
No.
Why check for duplicate charges?
Duplicate lines can trigger edits, denials or inaccurate billing.
