Access urgent updates and information on eOphthalmic downtime

Urgent Updates
PLANNED DOWNTIME OF CHI XML
CHI XML will be unavailable for one hour from 7am to 8am on Monday 19 October 2026.
What this means for your practice: most submissions should be unaffected. However, eOphthalmic may need to check CHI when patient information cannot be matched in our payment system, or when a match does not include a CHI number. If this happens during the downtime, your submission may fail. Depending on how you access the service, you may receive an 8410 Service Not Available message or, if using the query string or Ophthalmic Web Form (OWF), a message stating that the patient has not been found. Please note: we have a high percentage of CHI numbers held within our payment system, so this is expected to be low impact.
What you need to do: if your claim is affected, please resubmit it after 8am, when the service is available again.
