Trump ordered hospitals to post their Chargemaster on their websites, so local data is available to all of us. At my hospitals, it’s almost hidden, at the very bottom of the website, but it’s “find-able”.
Re: Trach specifically, a trach bumps the patient to the highest or 2nd highest DRG. So (I suspect) that the charges reported in this article are influenced not by the trach itself, but rather the other factors associated with the need for a trach & trach care (e.g.: ICU stay, vent charge, resp therapy & associated charges, etc).
For Medicare, heart transplant with major complication (trach, need for MCS, etc) is the highest reimbursement case, and at our place, has the highest average hospital bill/charges. Liver transplant and ECMO are waaaay up the list, too.
