A number of mental health teams are to be run by an Integration Joint Board (IJB) rather than NHS Grampian.
The health board currently manages all inpatient and specialist mental health and learning disability services (MHLD).
But by April, they are set to move to the Aberdeen City Integration Joint Board.
The City IJB will lead the services on behalf of the three Grampian Integration Authorities: Aberdeen City, Aberdeenshire and Moray.
The services being moved from NHS control include inpatient and specialist services at the Royal Cornhill Hospital, outpatient eating disorder and psychotherapy appointments and Child and Adolescent Mental Health Service (CAHMS).
Many other health boards in Scotland have made similar arrangements in a bid to make ends meet.
Council papers, to be discussed by Aberdeen’s IJB on Tuesday, and before Aberdeenshire Council on Wednesday, state: “On April 1, NHS Grampian plan to transfer the revenue budget to the IJBs and will ensure resource is available for the forecasted spend on Grampian-wide inpatient and specialist MHLD Services.
“There is currently a financial deficit within the inpatient and specialist MHLD services.
“NHS Grampian have agreed to underwrite any financial loss on inpatient and specialist MHLD Services for up to two financial year.
“Following transition to host arrangements, the IJB would continue to liaise with the relevant bodies across the North of Scotland and nationally in the provision of inpatient and specialist services – for example inpatient beds for Orkney and Shetland and the Eden Unit for the north of Scotland.”
Since April 2016, Moray IJB also delegated authority for inpatient services at Elgin and Seafield Hospital in Buckie.
Aberdeenshire IJB also has delegated authority for inpatient services in community hospitals at Fraserburgh, Inverurie and Banchory.
