Authorization of Payment


Some services or items covered by the Division of Medical Assistance Programs (Division) require authorization before the service can be provided. See the appropriate Division rules for information on services requiring authorization and the process to be followed to obtain authorization.


Documentation submitted when requesting authorization must support the medical justification for the service. A complete request is one that contains all necessary documentation and meets any other requirements as described in the appropriate Division rules.


The Division will authorize for the level of care or type of service that meets the client’s medical need. Only services which are medically appropriate and for which the required documentation has been supplied may be authorized. The authorizing agency may request additional information from the provider to determine medical appropriateness or appropriateness of the service.


The Division will not make payment for authorized services under the following circumstances:


The client was not eligible at the time services were provided. The provider is responsible for checking the client’s eligibility each time services are provided;


The provider cannot produce appropriate documentation to support medical appropriateness, or the appropriate documentation was not submitted to the authorizing agency;


The service has not been adequately documented (see 410-120-1360 (Requirements for Financial, Clinical and Other Records), Requirements for Financial, Clinical and Other Records); that is, the documentation in the provider’s files is not adequate to determine the type, medical appropriateness, or quantity of services provided and required documentation is not in the provider’s files;


The services billed or provided are not consistent with the information submitted when authorization was requested or the services provided are determined retrospectively not to be medically appropriate;


The services billed are not consistent with those provided;


The services were not provided within the timeframe specified on the authorization of payment document;


The services were not authorized or provided in compliance with the rules in these General Rules and in the appropriate provider rules.


Retroactive authorizations:


Authorization for payment may be given for a past date of service if:


The client was made retroactively eligible or was retroactively disenrolled from a CCO or PHP on the date of service;


The services provided meet all other criteria and Oregon Administrative Rules, and;


The request for authorization is received within 90 days of the date of service;


Any requests for authorization after 90 days from date of service require documentation from the Provider that authorization could not have been obtained within 90 days of the date of service.


Payment authorization is valid for the time period specified on the authorization notice, but not to exceed 12 months, unless the Client’s benefit package no longer covers the service, in which case the authorization will terminate on the date coverage ends.


When clients have other health care coverage (third-party resources, or TPR), the Division only requires payment authorization for the services that TPR does not cover. Examples include::


When Medicare is the primary payer for a service, no payment authorization from the Division is required, unless specified in the appropriate Division program rules;


When other TPR is primary, such as Blue Cross, CHAMPUS, etc., the Division requires payment authorization when the other insurer or resource does not cover the service or reimburses less than the Division rate.
