Overview
Domains 1-3 account for 63% of the CEHRS exam. This review session hits the highest-yield facts in each domain — the specific numbers, names, and rules that appear on the exam most frequently.
Key concepts
Documentation domain must-knows: H&P within 24 hours of admission; operative report dictated immediately; discharge summary within 30 days; delinquent records at 30 days; Joint Commission delinquency rate <50%
- Amendments vs alterations: never delete or overwrite clinical documentation; all corrections via addendum with original visible; late entries must be labeled as "late entry" with current date/time and reason
- Authentication: every entry must be authenticated (signed) by the author; co-signature requirements depend on state law and facility policy; electronic signatures are legally equivalent to handwritten signatures when compliant with e-signature laws
- Terminology domain must-knows: know the 50 most common prefixes/suffixes/roots; memorize the Joint Commission Do Not Use list; laterality must be documented for ICD-10 coding
- HIM domain must-knows: MPI duplicate rate target <2%; overlay = two patients merged incorrectly = patient safety event; break-the-glass access always logged and always reviewed; record retention: follow the longer of federal vs state requirement
- Release of information: valid HIPAA authorization must have all 8 required elements; 30-day turnaround for standard requests; workers comp disclosures do not require patient authorization for injury-related information
