MP Nadine Dorries has slammed GPs surgeries for profiting from telephone calls from their patients.
Several GP practices in the county only provide 084 numbers for patients wishing to contact their surgery.
These numbers are charged at higher rates than the geographical rate.
Surgerys that use 084 are:
Dr Basra, with practices at Bushmead Avenue, Bedford and Victoria Road, Bedford
Dr Kirkham and partners, Biggleswade Health Centre, Saffron Road, Biggleswade,
Dr Ling and partners, The Highlands, Flitwick
Dr Marner and partners, Cater Street, Kempston
Houghton Close Surgery, Ampthill
Salisbury House Surgery, Lake Street, Leighton Buzzard.
Numbers beginning with 084 cost up to four pence a minute more than using the standard area code number.
This means that people ringing their surgeries for appointments or advice will have to pay a premium rate.
Phoning from a mobile phone can be up to 40 pence more expensive a minute.
Telecommunications watchdog Ofcom has said that public sector bodies should not use chargeable 08 numbers Mrs Dorries said, "I am extremely concerned about the use of non-geographic, and higher rate, 0844 and 0845 telephone numbers by GP surgeries and out-ofhours doctor services and the implication this may have on access to care for patients.
"The Minister for Care Services recently intimated that there would be a gathering of evidence by the Government into the problem, though he stopped short of making a firm commitment on the matter of contact with GP surgeries.
"I am committed to an NHS whose services are shaped around the needs and preferences of individual patients, and which works to reduce, not exacerbate, health inequalities - the use of costly non-geographic numbers, after all, is likely to affect those on low incomes or with chronic illnesses most severely.
"I will continue to press the Government on their handling of this matter in terms of GP services."
A PCT spokesman said: "We wrote to all GP practices in Bedfordshire earlier in the year, advising that the Department of Health is currently looking at the use of 084 numbers in response to patients' concerns about higher call charges in some situations.
"A small number of practices had already adopted 084 numbers to improve telephone access for their patients.
"We would want to ensure that such systems benefit rather than disadvantage patients and have advised that any other practices considering changing to this number should not do so until there is clear guidance on this from the Department of Health which is expected soon."
