Not later than thirty days after receipt of the claim, the third-party payer shall notify all relevant external sources that the supporting documentation is needed. All such notices shall state, with specificity, the supporting documentation needed. If the notice was not provided in writing, the provider, beneficiary, or third-party payer may request the third-party payer to provide the notice in writing, and the third-party payer shall then provide the notice in writing. If any of the supporting documentation is under the control of the beneficiary, the beneficiary shall provide the supporting documentation to the third-party payer.
The number of days that elapse between the third-party payer's last request for supporting documentation within the thirty-day period and the third-party payer's receipt of all of the supporting documentation that was requested shall not be counted for purposes of determining the third-party payer's compliance with the time period of not more than forty-five days for payment or denial of a claim. Except as provided in division (B)(2)(b) of this section, if the third-party payer requests additional supporting documentation after receiving the initially requested documentation, the number of days that elapse between making the request and receiving the additional supporting documentation shall be counted for purposes of determining the third-party payer's compliance with the time period of not more than forty-five days.
Third-party payers and providers shall, in connection with a claim, use the most current CPT code in effect, as published by the American medical association, the most current ICD-10 code in effect, as published by the United States department of health and human services, the most current CDT code in effect, as published by the American dental association, or the most current HCPCS code in effect, as published by the United States centers for medicare and medicaid services.
It is not a violation of the notification time period of not more than fifteen days if a third-party payer fails to notify a provider or beneficiary of material deficiencies in the claim related to a diagnosis or treatment or the provider's identification. A third-party payer may request the information necessary to correct these deficiencies after the end of the notification time period. Requests for such information shall be made as requests for supporting documentation under division (B)(2) of this section, and payment or denial of the claim is subject to the time periods specified in that division.
