…I do have first hand knowledge of some US Health insurer's delaying treatment authorization or outright denying coverage as a normal practice.…
It seems my Med.Advantage plan hadn't played games with me in all the years been enrolled. Maybe it's because I'm domiciled in the right place.
Once after hospital surgery my hospital sent me notification that I owed them several thousands of dollars for a specific test done at that time. After I reported this to my Med.Advantage approved surgeon he was adamant it was necessary and promised to look into it. All I know is when I checked back with the hospital billing department they told me everything had been resolved and I owed U$0.00.
Another time a specialist wanted a specific diagnostic test and at first the Med.Advantage plan notified me that Medicare did not approve of that test so Med.Advantage couldn't cover it's cost. Again this doctor who is in my Med.Advantage HMO plan's network of providers (as they're called) challenged the postion. He did what is termed a "Doctor to Doctor" appeal which means personally contacted the Med.Advantage plan's supervisory medical Doctor engaging in professional explanation of why he, as my specialist, needed that diagnostic test. And yes, my Med. Advantage plan paid for it even though Medicare wouldn't pay them back U$0.01.
As for time delays; nope:
My Med.Advantage primary care Doctor has sometimes seen me and decided he wanted me to start consulting a new specialist. In more than one instance he explained that he would be submitting referrals to Med.Advantage on an "urgent" classification basis. And in a matter of days the Med.Advantage plan's local coordination administration ("P.C.P.") has telephoned me who/what/where I am authorized to contact for an appointment since they knew their mailed out authorization might be slow.
Likewise when specialists decided they wanted particular diagnostic tests to get a handle on my issues they put in "urgent" categorized requests which my Med.Advantage always approved all of in a prompt manner. Fortunately I reside in a city/town with many types of medical testing facilities which usually can schedule me in about 1 week or less. In one situation my specialist reviewed my testing and arranged for Med.Advantage to authorize a surgical intervention so fast I was in the hospital 3 days later - the hospital billed over U$100,000 of which Med.Advantage negotiated the settlement with no out-of-pocket cost to me.
Both times when one of my specialists moved or left my Med.Advantage HMO approved provider network they initiated contact notifying me. My plan then provided me with alternative Doctors in my network and after I contacted those finding one with openings for me Med.Advantage gave me an authorization to see the Doctor. The Med.Advantage plan had/has nothing to do with any delay(s) in getting any medical office appointment slot.
One specialist proposed an invasive procedure and when I inquired over the phone my Med.Advantage representative promptly provided me authorization for a 2nd opinion specialist. In that situation and others of a similar vein I've been able to discuss with the Med.Advantage representative exactly which specialists were in my network for planning my logistic convenience (I don't have a private vehicle).
Then to, my Med.Advantage primary care Doctor ("PCP") the family's long term physician who over the years got too ill to come into the office arranged for his associate to handle his patients. Eventually the Medical Group notified me that my original Doctor had formally retired so I contacted my Med.Advantage plan to officially update the name of my primary care physician. Well the representative couldn't find that Doctor in the P.C.P. network and it turned out he was not eligible because was strictly in the specialist classification of HMO participants. In turn the on-duty Med.Advantage supervisor waived that categorical restriction assuring me that the Doctor who'd been handling my care would continue being my legitimate primary care Doctor - duly sending me a new plan member card with the updated Doctor's name.
Lastly if it seems I've been overly active on this relatively fresh Original Post it's partly because have down time while have been and continue being in the midst of several specialist interventions all of which my Med.Advantage HMO plan has promptly approved for me. Yesterday I came home after yet another out-patient surgery attended by a team of nurses, anesthesiologist and neuro-surgeon whose group medical practice will bill Med.Advantage well over U$1,000 and get paid whatever amount Medicare approves. But as for me, well I've no co-pay due. And before the next 30 days have passed I've 2 more relatively costly medical interventions scheduled my U$0.00 monthly premium Med.Advantage plan is covering.
