How long the record must be kept
Licensed optometrists SHALL MAINTAIN RECORDS OF EYE EXAMINATIONS AND PRESCRIPTIONS FOR A MINIMUM OF FIVE YEARS FROM THE DATE OF EXAMINATION OR PRESCRIPTION.
- Provider class
- Washington licensed optometrists
What this means operationally
Five years, and the clock is per-EVENT rather than per-patient: it runs from the date of the examination or of the prescription, so a single patient file contains items ageing out on different dates and the record cannot be destroyed as a unit. The record class is also narrower than a general chart — eye examinations and prescriptions are what the rule names, which leaves other optometric material outside this particular duty.
Applies when
- A Washington licensed optometrist performs an eye examination or issues a prescription
