Thanks for this! I ran into it the hard way with one of my clients that I have been billing 90837’s for. They didn’t reimburse for any of them. My office person tried to change it to 90834 only to have them say we are trying to double bill. Ugh! Another client of mine with UHC I’ve never had a problem with the 90837 though. I’m guessing it’s the plan they choose.
Hey Jason, it is actually a national policy for 90834 to be unauthorized by default and 90837 to require authorization by default. While some plans and carve out policies differ, it’s a good general rule that you’ll need to call to obtain authorization for 90837 sessions.
hi. Do you know what rate UHC/oxford pays in network for a 90834?
Thanks.
This is one of those unanswerable questions because it depends on your contracted rate which is unique to you based on your location, license, specialties, and other factors. Your rate is determined when your contract is signed or renegotiated.
Hi Denny, any idea where I could find this policy. had a 90834 claim denied stating required preauth from UHC…
It’s always stated when calling about eligibility and benefits so the rep will let you know prior auth is required for 90837 when/if you ask.
They also pay 90837’s without an auth based on the DX. Some plans that say they don’t allow 37’s will pay because the DX is valid. Also, some plans allow for 90837’s to be billed no hassle. It’s plan specfic.
I tend to agree, but rather we say that it is diagnosis specific. Optum doesn’t default to allowing 60 minute sessions and when there is a diagnosis that warrants a 60+ minute session, it is often for crisis therapy. In that case we bill differently. So yes, technically if you were to bill the same extreme diagnosis each time it may work, but this is often audited as it is unlikely to be based on medical necessity. We do not recommend doing this.
You should remove this statement: “You most definitely can get 90837 sessions authorized.” That is far from true. They will only approve 90837 for specific diagnosis such as PTSD with specific therapies such as exposure therapy. I say you most likely will never get a 90837 pre-authorized through UHC/Optum.
This does depend on the client’s needs and medical necessity. It’s always best to call in advance and ask if you do think there is a reason for 60 minute sessions. Most providers prefer to just bill UHC with 90834 for a 45 minute session and perhaps see the client slightly more often.
Does this apply if you are considered out of network with United or just for in-network providers?
Both, great question!
