The patient participation group at the Greenwood Surgery, in Essex, set up the page to help the struggling practice cover the cost of electricity bills, heating and basic equipment. Donations to date have hit £2,700.
The cash-strapped practice's single-handed partner has been forced to raid his own pension fund to top up its funding, handing over more than £8,000 in November last year.
And the GP changed his name by deed poll in 2013 from Dr John Cormack to 'Dr John Cormack the family doctor who works for the NHS for free' to highlight the chronic funding issues his practice faced.
He has also released a parody song on YouTube to highlight the problems, which features Dr John Cormack the family doctor who works for the NHS for free and other practice staff dancing to lyrics spelling out their plight.
Patients at the practice launched the crowdfunding appeal warning that extra financial support was vital to maintain care at the Greenwood Surgery.
The page says that Dr John Cormack the family doctor who works for the NHS for free works 'very long hours', and 'has to regularly pay his own money into the practice to keep it running'.
It adds: 'To continue to treat his 4,410 patients in the excellent manner they have become accustomed to, we need your help as the surgery is in desperate need of cash, not to pay Dr Cormack, but to go towards the surgery's basic running costs: electricity, heating, equipment upkeep etc.
'Please give as much as you can comfortably afford, whatever that may be, it is very much appreciated.'
