The source listed at the end of this post provides another example of medical billing abuse by health care providers, medical billing services, and health insurance companies. Under Connecticut law, it is illegal for any "health care provider to request payment" from a person who has health insurance, other than a copayment or deductible, for medical services covered under a managed care plan. (See Connecticut General Statutes Section 20-7f.) Unfortunately, this statute is largely ignored by medical providers and their billing services, to the detriment of patients. This practice is often called "balance billing" in the medical billing industry.
