Received following reply from Tufts:  "Hi Brad   Looking in our systems, Spectrum Neuro Behavioral Care LLC (TIN# 83-4482753, NPI# 1356906572) is not contracted.  Tufts primarily contracts at the provider level and links them to the group to bill for their individually contracted rates, so this is standard.  If you seek a group contract, I would email the BH Contracting dept (AHCBehavioralHealth@tufts-health.com) and CC us (Tufts Cred email).   Thank you Provider Operations"  Sent email to AHCBehavioralHealth@tufts-health.com as instructed:  "Good morning,  I hope you're doing well, I wanted to know what would be required from our end to initiate a group contract request for the following group: Group Name# Spectrum Neuro Behavioral Care LLCTIN# 83-4482753 Please get back to me as soon as you're able to. Thanks."
