Email received from : HumanaHoustonPD@humana.com  Sub : Enrollment Documents - BHUCC - Humana  Did you ask customer service for the approval letter?  We do not have access to them.   Replied :   Good morning!  Hope all is well. Yeah I asked about the approval letter because she informed me that credentialing of the provider is in the last stages. Please provide me with the latest updates soon.  If you need any information from me please let me know. Waiting to hear from you soon.  Thank you! Have a great day!
