How can a HIPPA authorization can be revoked?

A HIPAA authorization can be revoked by the individual who provided it at any time, as long as the revocation is made in writing. The individual must inform the covered entity, such as a healthcare provider or health plan, of their decision to revoke the authorization. However, the revocation does not apply to information that has already been disclosed in reliance on the authorization prior to its revocation. It's important for patients to check with their healthcare provider for specific procedures on how to effectively revoke their authorization.
