GMHBA isn't connected to HaltH yet, so your practice can't claim it on the spot. You pay the full fee and claim the benefit back from GMHBA using your HaltH receipt. Here's how.
What you'll need
Your HaltH invoice (also sent via SMS and email after payment).
Your GMHBA membership details and bank account.
Claim through the GMHBA member portal
Log in to the GMHBA member portal.
Select Submit a claim.
Upload your HaltH invoice.
Select Submit.
