Informatics, Documentation, and Technology
Data is only as good as its entry
Informatics questions test whether you understand the path a service takes from documentation to payment, and where it can break. Know the core systems: the EHR for clinical documentation, the practice management system for registration, scheduling, and charge entry, the charge master, coding and encoder tools, edits engines and claim scrubbers, the clearinghouse, and the payer. Familiarity with standard transactions helps: the eligibility inquiry and response, the professional claim, the remittance advice, and electronic funds transfer. So does the general idea of interoperability standards that let systems exchange data.
On documentation, know the integrity risks: cloned or copy-forwarded notes, templates that pre-fill findings the provider did not perform, late entries without attribution, and addenda that rewrite history. Auditors look for these patterns, and payers treat them as evidence of unsupported billing.
Traps
- Password sharing or shared logins; the audit trail then attributes your work to someone else.
- Assuming the EHR prevents errors; it only enforces the rules someone configured.
- Copying forward an assessment from a prior visit.
- Assuming a backup exists without verifying that a restore has been tested.
- Sending protected health information by unencrypted email or text because it is faster.
- Using a template that auto-populates review of systems or exam findings.
Rule of thumb
The audit trail is the record of record. If the system cannot show who did what and when, treat the action as undocumented.
Worked example: During an internal audit, three notes for different patients contain identical, highly specific exam text. That pattern suggests template cloning. The fix is not to edit the signed notes but to correct the template, retrain the users, and re-audit; retrospective editing of a signed note is itself a documentation integrity problem.
