Claims that a new bedblocking crisis is set to hit Birmingham have been denied by the city council.
But the authority has allocated an extra £1.5 million to help care homes meet the need for new places.
Labour MP Roger Godsiff (Sparkbrook & Small Heath) accused the local authority of deliberately withholding funds to force people to stay longer in hospital.
This would mean the NHS pays for their care rather than the social services department of the city council, which is responsible for care homes.
But the authority denied the charge, and said the cabinet had decided earlier this week to provide extra funding for care home places.
Bed-blocking, officially known as delayed discharge, occurs when a patient cannot be discharged from hospital because no suitable care home place is available for them.
When the problem was at its worst, in 2001, Birmingham hospitals became so full that operations were cancelled and paramedics were even forced to provide emergency treatment in ambulances.
According to the city council, there are 94 cases of bedblocking in Birmingham. The figure is roughly the same as 12 months ago. A council spokeswoman said many of these cases were nothing to do with a lack of funding.
Mr Godsiff said: "Just recently, I have received a number of letters from concerned relatives of constituents in hospital, all of whom are at their wits end because the council has not provided the necessary funding to move their relatives out of hospital into residential care.
"A continuation of the current situation is clearly unacceptable and I want to know from the council what the problem is?"
Councillor Sue Anderson (Lib Dem Sheldon), cabinet member for social care and health, said: "The city council is currently reviewing the situation given that this service is having to respond to the fact that people are living longer and the demands for the service are increasing."
