I mentioned there are tons of paperwork involved when getting money from Insurance companies, here is link explaining why more doctors opt for cash only services.
Cash-only doctors abandon the insurance system - Jun. 11, 2013
NEW YORK (CNNMoney)
Fed up with declining payments and rising red tape, a small but growing number of doctors is opting out of the insurance system completely. They're expecting patients to pony up with cash.
Some doctors who have gone that route love it, saying they can spend more time with and provide higher-quality care to their patients. Health advocates are skeptical, worrying that only the wealthy will benefit from this system.
In Wichita, Kan., 32-year old family physician Doug Nunamaker switched to a cash-only basis in 2010 after taking insurance for five years. ("Cash-only" is a loose description. Nunamaker accepts payment by debit or credit card too.)
Under the traditional health insurance system, a large staff was required just to navigate all the paperwork, he said. That resulted in high overhead, forcing doctors like Nunamaker to take on more patients to cover costs. Plus, the amount insurance companies were willing to pay for procedures was declining, leading to a vicious cycle.
"The paperwork, the hassles, it just got to be overwhelming," Nunamaker said. "We knew that we had to find a better way to practice."
==================================================
I don't want to share much of my issues in public, this is the reason why I understood this perfectly clearly. I am currently in legal mess with health insurance agencies and that is how I know whats going on. What happened to me CAN happen to anyone, does not matter which state one lives. The truth is Insurance companies ARE playing games and doing everything they can to refuse the claim, result no doctor wants to treat me! Its all finger pointing and it is UNREAL.
