© Sebastian Zeki 2012   Patients are ultimately responsible for their own fees.   An insurer would normally require you to have a referral letter from your GP. If you have insurance it is important that you confirm that you are covered for the cost of any  consultations and treatments and that you have any authorisation details available when you   attend.   We believe it is important that patients can get an estimate of likely costs before embarking on a course of  treatment and for a fees estimate please contact Dr Greenfield’s secretary Linda on  kerri.knight@nhs.net and she will be able to send you a list of fees (this will not include hospital  charges).
