re: Thomas B. Loring 5 Brigantine Lane North Quincy MA 02171 d.o.b. 05-12-1931 Medicare: 033-30-4243A D00324567 Blue Medicare Rx (PDP) Coverage Determination/Appeals Department MC 109 P.O. Box 52000 Phoenix AZ 85072-2000 .PP Please be advised that Mr. Loring, the above-captioned patient has open angle glaucoma treated hitherto with Xalatan eye drops. Most recently, instead of the trade-marked "Xalatan", Mr. Loring's druggist dispensed to him the generic equivalent "latanoprost". .PP Mr. Loring is under the impression that his insurance policy will no longer pay for Xalatan because a generic equivalent is available, and will not pay for the much less expensive generic equivalent lanatoprost because of an administrative error on the part of his insurance company. .PP Please investigate this anomaly. Please provide payment for either lanatoprost or Xalatan. Please advise both Mr. Loring and myself of your determination. .PP Thank you for your help. .nf Sincerely yours, Ernst J. Meyer, M.D.
