Coverage Compass Journal
Not insurance copy. Writing about what healthcare feels like when the system gets between a person and care.
The blog is where Coverage Compass goes beyond definitions. These pieces examine the decisions hidden inside insurance language: who waits when an authorization is delayed, who does the work behind an appeal, what “in network” means when nobody is accepting patients, why medical debt is not just a budgeting problem, and why physician policy belongs in a patient-access conversation.
Some articles are practical guides. Others are arguments, field notes, or questions I think future physicians should be asking. Every piece is meant to leave you understanding more than a vocabulary word.

When the answer is "that is what the rule says," the next move is the rule. The policy tracker shows what is law, what is moving and what is at risk — and the legislative playbook shows how to weigh in.
