The Single Case Agreement

Practices tend to treat every single case agreement the same way — as a request to a payer that may or may not be granted. That framing is right for one of the three cases and wrong for the other two, and being wrong about it costs money in a way that never appears on a report.

The network cannot furnish the service

The plan covers the benefit and has no contracted provider who can deliver it — because of geography, subspecialty, capacity, or timing. This is the case where the plan is under an obligation, and the section below sets out where that obligation is written for the two big managed-care programs.

Continuity of care

A patient is mid-course when a contract ends or their coverage changes, and interrupting the treatment is the worse outcome for everyone. Not the same obligation as the first case, but not a blank page either — plans generally have their own continuity-of-care provisions, and where they exist the agreement is being fitted to a process rather than invented.

A genuine one-off

The patient chose this practice, the service is available in network, and nothing compels the plan to agree to anything. This is the pure negotiation, and it is the only one of the three where the practice's leverage is the whole story.

For the two large managed-care programs, the network-inadequacy case is addressed directly in federal regulation. Neither provision is about single case agreements as such — an agreement is simply one way the plan discharges the obligation — but knowing they exist changes how a practice reads the plan's position.

Two boundaries. Commercial coverage outside these programs is governed by the plan's own terms and by state law, which vary and are not summarized here. And where an out-of-network situation is one the No Surprises Act addresses, that Act supplies its own protections and its own dispute route — a statutory process after the fact, as against a negotiated agreement before it. The Act's notice and consent rules and its independent dispute resolution process own that ground; none of it is restated here.

A single case agreement is a contract, and it has to do what a contract does: leave nothing important to be worked out later by whoever is looking at the claim. The list below is short and every item on it has a failure mode attached.

1. 01

   Who, precisely

   The patient, the member identifier, and the billing entity — the same identifiers that will appear on the claim. An agreement naming a practice whose claims come in under a different billing identity has already introduced the mismatch that will deny it.
2. 02

   What, and for how long

   The services or codes covered, or a clearly defined episode, and the date range. An open-ended agreement is comfortable to sign and hard to enforce, and a payer's reading of what it covered is the one the remittance will reflect.
3. 03

   How much, stated as a basis

   Not an amount alone but the basis it comes from — a case rate, a per diem, a percentage of a stated schedule, or a fee schedule identified by name and version. A rate with no basis is unverifiable when the payment arrives, and cannot be reconciled against anything.
4. 04

   Whether authorization is included

   This is the item that most often turns a good agreement into a denied claim. An agreed rate is not an authorization. If a separate authorization is still required, the agreement should say so and the practice should obtain it before the service — the prior authorization request checklist covers what that request needs.
5. 05

   How the claim will be recognized

   The most consequential and the most often omitted. Something has to connect the submitted claim to the agreement — a reference number, a specific submission address or queue, a required field. Without it the claim arrives as ordinary out-of-network work and is adjudicated as such.
6. 06

   Filing window, appeals, and the patient's share

   Which filing deadline applies, what appeal route exists if the claim is mishandled, and exactly what the patient owes — with the practice's balance-billing position stated rather than assumed.

Almost never on the rate. The rate is the part everyone concentrates on, which is exactly why it is rarely the problem.

• The claim is not connected to the agreement. It submits like any other out-of-network claim, is adjudicated like one, and denies or underpays. The agreement was real; nothing on the claim said so.
• The rate was agreed; the authorization was not. Two different approvals from two different parts of the payer, and having one does not produce the other.
• The scope drifted. The episode ran longer, or additional services were needed. Whether the agreement covers them is a question best answered before they are furnished, and the answer is often an amendment rather than an argument.
• Nobody owned it after signature. An agreement that is not attached to the account, and not known to whoever works the denial, is invisible at exactly the moment it matters. Whoever negotiated it should not be the only person who knows it exists.
• The patient was told something different. The plan's obligation about cost sharing and the practice's own billing position have to match what the patient was told at the outset, or the agreement resolves the payer relationship and creates a patient one.
