Gary Larson has a $5,000 deductible insurance plan, but has found that his medical bills are cheaper if he claims he's uninsured and pays cash. Using that strategy, an MRI scan of his shoulder cost him $350. His brother-in-law went to a nearby clinic for an MRI scan of his shoulder, was billed $13,000, and had to come up with $2,500.
Kaiser member Robert Merrilees had a colonoscopy at an affiliated surgery center, which charged $7,500. His co-pay was $15, Kaiser picked up $470, the rest of the bill "just went away." Merrillees was left scratching his head over the crazy math in medical billing.
