I just got an email as a part of my undercurrents magazine subscription that had some information about DAN. This is a good resource for divers and you can subscribe at undercurrents.com. Any way Ben Davidson of undercurrents wrote the following, I hope it helps with some of the confusion-

"Recompression Chambers Reject DAN America Insurance: The SSS Recompression chamber network, operator of hyperbaric chambers in a dozen popular dive destinations, has announced that some facilities will no longer accept the Divers Alert Network (DAN) America insurance for payments at some chambers: Nassau, Bahamas; Cabo San Lucas, Merida and Cancun, Mexico. SSS has other chambers, which they say may also stop accepting DAN insurance payments: Cozumel and Playa Del Carmen, Mexico; Ambergris Cay, Belize; the Galapagos Islands, and five in Thailand. In a prepared statement, SSS declared it could "no longer tolerate unpaid services, and since the only insurer in the world who has refused to settle our bills is DAN America, some SSS chambers have no other choice but to ask DAN America patients to pay for services when rendered and file the claims themselves with DAN America." SSS owner Mauricio Moreno told Undercurrent that their chambers are still "duty bound to render services despite a patients' ability to pay." SSS has filed a lawsuit against DAN over the matter.

DAN issued a statement saying: "The dispute involves what constitutes reasonable and customary charges for hyperbaric chamber treatment. Even though some insurers may have signed exclusive arrangements with [SSS] in exchange for lower rates, DAN believes exclusive arrangements are not in the diver's best interest, when the diver needs help at the nearest available chamber to avoid medically unacceptable delays." DAN CEO Dan Orr told Undercurrent that discussions are ongoing and he hopes to work out a solution "that's right for DAN members as well as the industry."

Meanwhile, make sure your credit card limit is high enough to cover emergency medical expenses, no matter what insurance you carry. The full story will be in the February issue of Undercurrent."
