Case Study 1 — The Address: A Composite

Constructed. The practice, the patient, and the figures are not real. The mechanism — a wrong address that produces no denial, no rejection, no work queue item, and eventually a collection action against someone who was never told — is ordinary, and it is the only failure in this chapter that generates no signal of any kind inside the billing system.

Background

Section 24.2 listed the registration fields that cause denials and then said something odd about one of them:

A wrong address produces no denial at all — it produces a patient who never receives a bill, an account that ages, and eventually a collection action against someone who was never told.

Every other field on that list fails loudly. This one fails silently, in the patient's direction.

The composite

Constructed.

A patient moves. She is conscientious about it — she files a change of address, updates her bank, and tells her employer.

She does not think to call a medical practice she has visited twice.

Eight months later she has an encounter. At check-in she is asked to confirm her insurance card, which is unchanged, and she does. Nobody asks about her address, because the record has one and it looks complete.

The claim goes out and pays correctly. A patient balance of a few hundred dollars remains after the plan's payment.

What happened to the statements

Statement one goes to the old address. Returned to sender, and — this is the part that matters — the return is handled by whoever opens the mail, which in most practices is not the person who manages the account.

(Constructed.) The returned envelope is set aside. Nobody updates the record, because updating a record requires knowing the new address, and the envelope does not contain one.

Statements two and three go to the same address. Two more returns.

A telephone number is on file. It is her old landline, disconnected at the move. Two calls, both unanswered, both logged as attempted.

At around 120 days the account is placed with a collection agency, under a policy that is written down, reviewed, and entirely ordinary.

What the patient experienced

A collection notice, at her new address — because collection agencies have skip-tracing tools that medical practices do not.

That is the first she hears of any of it.

She calls the practice, upset, and is told that three statements were sent and two calls were made. All true. She says she never received them. Also true.

(Constructed.) She pays the balance immediately, because she is the sort of person who does. The account is resolved in one phone call, seven months after the encounter, and after a collection placement that appeared on her credit as a matter of routine.

What it shows

First, the address is the only registration field whose failure is invisible to the billing system. Every other field on §24.2's list produces a rejection or a denial — something enters a queue, someone looks at it. A wrong address produces a claim that pays.

Second, the returned mail was a signal and nobody was assigned to it. This is the entire failure in one sentence. The envelope came back. The organization received, three times, physical evidence that its contact information was wrong — and the evidence arrived at a mailroom rather than at an account.

Third, the escalation policy worked exactly as designed. Three statements, two calls, 120 days, placement. Nothing about the policy is unreasonable, and a practice that did not have one would be worse off. The policy simply has no test for whether the patient was ever reached.

Fourth, the collection agency found her in days. That is the detail that makes the story uncomfortable rather than merely unfortunate: the capability to locate her existed and was deployed only after the account was sold. A practice that had run the same lookup at the first returned envelope would have had her address in an afternoon.

And fifth — she did everything right. This is the fifth case study in this book with that property, after Chapter 16's observation stay, Chapter 18's maternity package, Chapter 19's standing order, and Chapter 22's drifted authorization. The book has now named this five times and Chapter 32 owes an answer, which its discussion questions have been demanding since Chapter 22.

What would have prevented it

Four things, in ascending order of cost.

Ask. "Is your address still 1400 Elm?" — read it back rather than asking whether anything has changed, because people answer "no" to the general question and correct a specific one. Five seconds.

Route returned mail to the account, not to a pile. A returned statement should place the account in a work queue with a specific status: address unverified. It is a status change, not a task.

Test the escalation policy for contact, not for attempts. "Three statements and two calls" is a count of actions. "The patient acknowledged the balance" is a count of outcomes. A policy that escalates on attempts will escalate against people it never reached, every time, by design.

And run the lookup before the placement, not after. If the organization is willing to pay an agency to find someone, it can find them itself for less, earlier, and without a collection action.

The lesson

Returned mail is the only evidence you will get, and in most organizations it arrives somewhere that cannot act on it.

Four carry-forwards:

Read the address back at every encounter. Not "has anything changed" — the actual street.

Make a returned statement a status on the account. Not a piece of paper on a desk.

Add one test to your escalation policy: was the patient ever reached? If every attempt failed the same way, the next attempt will too, and escalating is not a remedy — it is a change of venue.

And do the skip trace before you sell the account. It is cheaper, it is faster, and it is the difference between a phone call and a credit entry.

Discussion questions

1. The escalation policy was reasonable and produced an unreasonable outcome. Rewrite it. What is the new test, and what does it cost to administer?

2. The returned envelope arrived at a mailroom. Design the routing. Who receives it, what status does the account take, and what happens next?

3. The collection agency located her in days using tools the practice did not have. Should practices have them? What are the arguments against?

4. She paid immediately when she found out. How many patients in her situation do you think would? Does the answer change what the policy should be?

5. This is the fifth case study in which a patient did everything right and was harmed. Name what all five have in common — and then say whether the common feature is fixable or only mitigable.
