Somehow I think the national lab test company's lawyers have got them covered. This wasn't exactly a fly by night, no name company. Having in known third party send you a medical bill months later is pretty fucking common place. This was just one anecdote of many, not an isolated incident.

Not when the lab and the hospital are owned by the same company. Promedica (local hospital) sent my sample to Promedica (lab) and I got a bill from the lab. Because Promedica (lab) didn't have my insurance information.
