A new €10m primary care centre in Ballyfermot in Dublin may have to open next month without any GPs, due to an issue over rent fees.
The facility was completed last month.
The Health Service Executive says it has offered GPs who practise rent free out of the old HSE health centre, accommodation in the new centre for a nominal rent fee.
Local Fine Gael TD, Derek Keating claimed some local GPs were refusing to support the Government's primary care strategy.
He called on the Minister for Health to advertise for new GPs to take the facilities on offer.
The Irish Medical Organisation, which represents GPs said it rejected the claims by deputy Keating.
Eric Young, Assistant Director of Industrial Relations with the IMO, said there were contractual arrangements in place for GPs to provide services and it wanted to ensure these are adhered to.
He said the IMO was in talks with the HSE but if these discussions fail, the IMO would be happy to go to arbitration provided for under the medical card contract.
The HSE said it had met the IMO on the issue and the executive says it is willing to go to arbitration on the matter.
The centre will serve Ballyfermot, Cherry Orchard and Palmerstown.
It will provide mental health, dental and addiction services as well as a crèche and pre-school services.
The HSE plans to open the facility at the end of April.
