MAKING A PAYMENT MY DOCTOR: WHERE'S MY CLIENT ID?

So, I'm attempting to pay my statement, and more info it says I need a client ID. Here's the catch: I can't find it anywhere! Checked everywhere online. Did my doctor's office send it to me? Is there a separate portal? Any ideas on how to this client ID would be super useful. Logging in to Veradigm Pay My Doctor for Payment Issues Are you runni
