Pre-filing Conference

OHA encourages all entities to request a conference prior to filing a notice of proposed transaction. During a pre-filing conference, OHA and entities can discuss the filing process, whether the proposed transaction requires entities to file a notice, what forms will need to be completed, what information may be requested from entities, handling of confidential information, and submission timing. To request a pre-filing conference, please email hcmo.info@oha.oregon.gov.

To help with the transition, OHA is implementing a grace period through September 30, 2026. During this time, OHA will accept either the current or previous versions of the submission forms listed below. Beginning October 1, 2026, only current versions of the submission forms will be accepted.

Direct any questions related to forms or submission to hcmo.info@oha.oregon.gov.
