I've seen friends go to in-network hospitals and getting unexpected huge bills from out-of-network practitioners who treated them there, esp. during an operation when one has no prior indication of who the attending anesthesiologists or radiologists are and whether they are in-network or not. AB 72 attempts to fix this by 1) allowing those providers in-network charges only and 2) making any exceptions pretty tight. See Section 1371.9 in https://leginfo.legislature.ca.gov/face ... 520160AB72Currently, patients who schedule medical procedures at in-network facilities may still unwittingly receive care from out-of-network physicians who can bill them directly, bypassing insurance companies completely. Health care access advocates cheered the passage of Bonta's AB 72 as a huge victory.
"This bill is the most significant step any state has taken to protect patients who end up in the crossfire of billing disputes between insurers and providers," said Anthony Wright, executive director of Health Access California, a nonprofit health consumer advocacy coalition.
The exceptions to the new rule are pretty tight mostly. Emergency services are excluded from the above requirement unfortunately.
