Discovery Health service provider payment problems

In January 2021, I submitted three physiothe****** accounts for payment to Discovery Health.

After numerous emails and requests for them to respond, Discovery Health eventually rep**** with a Code 581 - this, after the physiothe****** provided Discovery Health with the ICD-10 codes! What more and what else to do to secure payments?

It has really been frustration upon frustration in dealing with Discovery Health with this - such a mission and a huge embarrassment for me!

I have never experienced any problems before as I always received good and swift service.
