I worked in lab EHR software and can say this is the correct answer. Lab pricing is particularly complex and is not like buying a hammer or a pedicure.
There was a separate billing module that calculated pricing for individual procedures based on a number of factors, such as insurance provider, diagnosis codes, performing lab, urgency, etc. along with a whole set of separate rules for medicare/medicaid patients. Even the timing of drawing blood (relative to other procedures) was factored in for insurers.
Transparency isn't going to help much here when the problem is the complexity created by multiple payers.
