Really good piece on health insurance practices in today’s L.A. Times that every consumer should read. Single-payer’s not looking so bad these days, huh?

Insurers say they are picky because they have to be.

Kaiser Permanente’s “fairly generous” benefits require that the health maintenance organization be restrictive to remain solvent, spokesman Jim Anderson said. “We have to be very careful to not enroll a bunch of people who are going to spend all the money on their care.”

Insurers declined to disclose the underwriting guidelines that lead to rejection or higher premiums. But a review of public records, as well as rejection letters sent to individuals, shows that California carriers turn people away or charge them higher premiums for conditions that range from the catastrophic to the common. Cancer, epilepsy and AIDS make the list, along with breast implants, ear infections, varicose veins and sleep apnea.

Jeffrey Miles, a vice president of the California Assn. of Health Underwriters, a trade group for independent insurance agents, said one of his clients — a 27-year-old woman “in perfect health with absolutely nothing wrong” — was rejected because she had seen a psychologist for three months after breaking up with a boyfriend.

“I call it hangnail underwriting,” Miles said. “If a person has taken virtually any medication, they are going to be turned down. If people have had any psychological counseling at any time in recent history, they are going to get turned down.”

Swartz, the consultant, said the reason she couldn’t get individual coverage was a condition in her records that she may never have actually had. Her physician had diagnosed ulcerative colitis. But after years without additional symptoms, Swartz said, her doctor decided the initial diagnosis was probably wrong.

Consumer advocates say out-of-date, ambiguous and even erroneous medical information can render people uninsurable. Sometimes the reasons can seem absurd. In a letter to an otherwise healthy recent college graduate, for instance, Blue Cross listed among the reasons it denied coverage a past bout of jock itch, “successfully treated with cream.”
