I’m a physician that works at an ultra specialized hospital.
Even if that were true that KP deny the least, it ends up meaning nothing if they also own the hospital who they graciously never deny claims from.
Ugh.
UHG denies.
KP delays.
Both can lead to disastrous consequences.
Edit: And by delay, I don’t mean delay in seeing a specialist, I mean delay getting the most modern and up-to-date care. They have a tendency to practice population based treatment (and fiscally responsible), which may not be what is the most up to date. I understand it as an hospital administrator, but I can see the consequences as a physician.
The partnership of Kaiser and Reagan are largely responsible for the healthcare system America has today.
Do not give them a pass.
