Why This Matters
A group sees “linking” in today’s portal and “affiliations” in MTHCS notices and assumes they are the same thing.
Timely operational post explaining a key claims-modernization requirement for groups.
What to Know First
Portal linking and claims-system affiliation are distinct concepts in Montana’s modernization materials; by MTHCS implementation, the rendering provider must have the required affiliation with the billing provider or claims may reject.
What to Verify Before You Act
Montana’s 2026 notice says MTHCS will require an affiliation between the rendering and billing provider for affected claims in 2027.
Practical Workflow
TL;DR: linked today does not necessarily mean affiliated for MTHCS.
Common Mistakes to Avoid
Treating old MPATH, MATH, ICAP, Passport, PCMT, or MTHCS references as interchangeable without checking the current Montana source.
Assuming a portal login, provider enrollment, provider linking, claim route, or future affiliation is complete just because one related task was approved.
Sharing owner credentials with a biller or staff member instead of using supported user access and offboarding controls.
Skipping eligibility, authorization, provider-record, and remittance checks before treating the workflow as payer-ready.
Where Bomi Fits
Bomi can audit provider rosters now and translate official MTHCS affiliation instructions into a claim-ready implementation plan when the tools go live.
For practice owners, the practical goal is simple: the provider record, portal users, eligibility workflow, authorization process, claim route, and remittance workflow should all match the way the practice actually operates.
