In observance of Juneteenth, state offices will be closed Thursday, June 19, 2025.  As a result, provider payments for the week June 16, 2025, will be made on Saturday, June 21, 2025, including the delivery of Remittance Advices (RAs) and HIPAA 835 remittance files.

Thank you.

Due to the timing of the State Biennium End and the observance of Independence Day, payments to providers for the week of June 30, 2025, will be delayed and made the following week on Tuesday, July 8, 2025. Remittance Advices (RAs) and HIPAA 835 files will also be made available on Tuesday, July 8, 2025.  Normally payments and remittance advice documents would be available for providers on Friday, July 4, 2025, but must be moved due to the Biennium end and the holiday.

Claim submission deadlines have been updated as reflected below to ensure that providers are able to receive payment and Remittance Advice documents on July 8, 2025.

The deadline for submission of claims to ProviderOne in order to receive payment on July 8, 2025, will be extended to 5 p.m. on Wednesday, July 02, 2025.

The deadline for submission of pharmacy claims to the Point of Sale (POS) in order to receive payment on July 8, 2025 will be extended to 5 p.m. on Tuesday, July 1, 2025.

Payment and claims submission deadlines for the week of July 7, 2025 will not be impacted.  Two payments will be made during this week.

ProviderOne Portal is returning error “Exception in fetching multiple list record” when the Client’s last name is submitted with an apostrophe from Page ID: dlgCreateBatchFromTemplate(Claims).

When navigating in the ProviderOne Provider portal some providers are receiving error messages when attempting to select certain hyperlinks, or when attempting to submit a claim.

The error message received can be one of many:

• A blank screen with a close button in the upper left corner
• A warning message at the top of page: 'The service code or modifier submitted is invalid'

All error messages may not be identified yet. These error messages may not be a ProviderOne issue. Many times, this indicates the Provider needs to allow the ProviderOne URL to their allowed sites under pop-ups and redirects in their browser settings.

We have become aware of a Remittance Advice reconciliation issue that occurred during last week’s payment and remittance cycle on January 1-3, 2025.  To be clear, this is a remittance issue, not a payment issue.  While we are still diagnosing the root cause and remediation, we want to provide assurance that payments made last week on January 3, were accurate.  Impacted providers received a Remittance Advice showing a lower payment amount than the actual payment amount received by the providers.  Once remediation activities have been defined, specific outreach will be conducted with impacted providers.

When OHP subscriber is accessing ProviderOne from OHP, OHP sends to ProviderOne the OHP role the OHP subscriber has associated.  When the ProviderOne security domain does not have ProviderOne profiles associated for ProviderOne profiles to OHP role, the incorrect message is displayed "No User Profiles assigned to the User. Please contact HCA ProviderOne Security”. 

The correct message is "Error: Please contact System Administrator. There are no ProviderOne profiles associated with your roles".
