(a) Claims from counties and providers for reimbursement of outpatient drug free, day care habilitative, narcotic treatment program, Naltrexone treatment, and perinatal residential treatment services shall be presented to the Department no later than six (6) months from the date of service, unless the county or provider has good cause, as specified in Sections 51008 and 51008.5. The county or provider shall produce, upon request by the Department for audit or monitoring purposes, documentation to substantiate the good cause.

(b) An additional unit of service, or a multiple service billing, provided to a beneficiary on the same day may be claimed up to the maximum amount allowable if the beneficiary's return visit is to the same provider and the return visit service is not a duplicate to, or the same as, the service previously provided to the beneficiary on the same day.

“Multiple billing” means a claim is being made for a return, face-to-face visit, which is for an additional service to a previously provided service on that same day. The county and/or provider shall prepare and retain, in the beneficiary's patient record, a Multiple Billing Override Certification (Form DHCS MC 6700 (Revised 6/2014)), hereby incorporated by reference, certifying that a review of the client's record substantiated the multiple service. The form shall be signed by the person authorized to represent the county and/or provider.
