Backwards and Bureaucratic

I rate any service as "terrible" when they do not do what they say. Stratum refuses to pay my claim because the invoices I submitted from the service provider do not have ICD 10 codes (whatever that is). The service provider in question, a well-known multinational entity, does not provide any documentation other than what I submitted to Stratum. So now I don't get paid out for a legitimate claim because of Stratum's own backwards and bureaucratic systems.
