Coverage is checked before anything you can influence
For a large share of patients the search begins with a plan rather than a practice, and everything else is a second-round question.
People search their insurer's name alongside a location, use their carrier's directory, or type a plan name with a procedure. The set of practices they end up considering was decided by that step.
A practice out of network is not competing on quality with a practice in network. It is competing against a patient's assumption that out of network means unaffordable, which is a different argument and has to be made explicitly.
Both positions are defensible and they need different content. In network wants the plans named plainly and findable. Out of network needs a genuine explanation of what it costs, how reimbursement usually works, and why some patients choose it anyway.
The out of network explanation is unusually absent online, and it is the highest value page a fee-for-service practice can publish. Most of the material a patient finds is written by insurers.
Keep it accurate and general. Coverage varies by policy and specific promises about what will be paid are not yours to make, so the useful version explains mechanics and tells people what to ask their own plan.
