Casey's LM's are tiny. They look like little red warts. When he gets a virus they enlarge, turn purplish and hurt a bit. Cody's surgery was covered under my HMO, after I appealed their denial for "In-net" coverage by proving that the local network of doctors could not provide what the "Out-of net" doctor could. Had it not been covered by my insurance, it would have been approximately $30,000.00 of which I would have had to pay the $6,000 co-pay for out-of-net treatment. Good referrals and additional doctor support was what won my appeal.
