Reading a provider network before you enrol

When a Medicare plan operates a network, the network is the part of the plan that will touch your life most often. It decides which doctors you can see, what you pay when you see them, and how much paperwork sits between a referral and an appointment. It is also the part most likely to be checked casually — a name typed into a search box, a green tick, and a decision made.

What a directory listing is, and is not

An online provider directory is a snapshot of what the plan believes to be true. It can lag behind reality in both directions: a practice that has left the network may still appear, and one that has joined may not yet. Directories are also organised by the entity that holds the contract, which is often a practice or a health system rather than an individual clinician. A listing can therefore be accurate about the practice and misleading about the particular doctor you intend to see.

A second distinction catches people out. Being in a network is not the same as accepting new patients, and neither is the same as accepting new patients with a particular plan. All three have to be true for an appointment to happen.

The questions that get a usable answer

Checking a network well means asking narrow questions rather than general ones. When you call a practice, the useful form of the question names the plan, the year and the clinician:

• —Are you in network for this specific plan name, for the coming plan year, not simply for this insurance company?
• —Is the clinician I want to see in network, or only the practice?
• —Are you accepting new patients under this plan?
• —Do you expect your contract with this plan to continue into next year?

That last question will rarely get a firm answer, and asking it is still worthwhile. Practices often know that a negotiation is underway before patients do.

Beyond your own doctor

A network check that stops at a primary care physician is incomplete. The facilities and specialists attached to care you may need are contracted separately, and the ones that matter are easy to overlook until they are needed:

• —the hospital you would want to be taken to, and whether it is in network
• —the specialists you see regularly, and the ones a current condition is likely to require
• —the laboratory and imaging centres your practice sends work to, which are often chosen by the practice rather than by you
• —anaesthesiologists, radiologists and similar clinicians involved in a procedure, who may be contracted independently of the hospital
• —pharmacies, which have their own network arrangements covered in a plan's drug documents

How the network behaves day to day

Networks differ not only in who is in them but in how they work. Some plans require you to choose a primary care physician who coordinates referrals to specialists. Some allow you to go directly to a specialist. Some cover care outside the network at a higher cost to you, and some generally do not cover out-of-network care except in an emergency. Prior authorisation requirements vary as well, and they apply to procedures and services rather than to people.

Travel is worth a separate thought. If you spend months of the year at another address, or regularly visit family in a different state, a plan built around a local network may fit your care pattern poorly even though every box ticks at home. Plans typically describe what they cover for urgent or emergency care away from the service area, and that description is the part to read rather than assume.

Networks change during the year

A network is a set of contracts, and contracts end. A practice or a hospital system can leave a network mid-year, and a plan is generally required to notify affected members and to describe what happens to care that is already underway. There are usually provisions for continuing a course of treatment for a period after a provider leaves, which is a question to ask promptly rather than later.

Write it down

Keep a short note of each check: who you spoke to, what you asked, the date, and what they said. It costs a minute and it is the only thing you will have if a claim is later processed as out of network. A list of the clinicians and facilities that matter to you, kept somewhere you can find it, also turns next year's network check from an afternoon of searching into a morning of confirming.
