A/R & Follow-Up
The receivable as a book of business — how it is segmented, prioritized, staffed, reported, and reconciled, rather than how one claim is chased.

What is accounts receivable follow-up?
Accounts receivable follow-up is the work of managing everything that has been billed and not yet resolved. Not one claim at a time — that is claim tracking — but the whole book: deciding which portion of it is worth working, in what order, by whom, and on what cadence, and knowing which parts of it are quietly becoming uncollectible while attention is elsewhere.
The distinction matters because the two are managed differently. Chasing an individual claim through statuses and payer contact is covered in Tracking a Claim. This section is about the portfolio the claim sits in: how the A/R aging is segmented, why the conventional buckets are a convention rather than a rule, and how a worklist gets built so that the accounts most likely to be recovered are worked before the ones that merely look urgent.
Almost every failure in A/R is a prioritization failure rather than an effort failure. A team working hardest on the largest balances is not necessarily working on the most recoverable ones, and a claim that quietly crosses a filing or appeal deadline while sitting in a queue is lost to process rather than to the payer. The articles here set out how to segment, sequence, and measure the work so those losses are visible before they are permanent.
No productivity benchmarks, no target days in A/R, and no collection rates appear in this section. Those depend on payer mix, specialty and contract terms, and a published average is not your data — the articles explain how to build the measure from your own volumes instead.
Where to start
From segmenting the book, to working it, to proving it. Articles are added to these steps as they publish.
Segment the receivable
Aging buckets and what they hide, insurance versus patient A/R, and analysis by payer — the views that make the book legible.

Designing an A/R Follow-Up Process
Follow-up fails by design more often than by effort. Four decisions define the function — and the first, what makes an account workable, is a state rather than an age.

The aging report answers one question and gets asked four. The bucket boundaries are a convention, the start date is a choice, and age is not a test of collectibility.

The only follow-up mechanism that scales to a whole book of claims — and the one most misread, because what it returns is a position rather than an explanation.

About this section
How is this different from tracking a claim?
Tracking a claim is claim-level: where one claim is, what its status means, and who to contact about it. That is covered in Tracking a Claim, under Claims. This section is portfolio-level: how the whole receivable is segmented, which part of it should be worked first, how much capacity that requires, and how the result is reconciled and reported. A practice can be excellent at the first and still lose money on the second.
Does this section publish target days in A/R?
No. Days in A/R depends on payer mix, specialty, contract terms, and how the practice defines its own denominator, so a published target would be someone else's number presented as your goal. The Days in A/R metric page specifies how the measure is calculated and the calculator computes it from your own balances; what these articles add is how to read a change in it.
Where does patient A/R belong?
Insurance and patient receivables are separated on purpose, because they are worked by different people under different rules. This section covers the separation itself and the reporting that keeps them distinct. Everything about collecting the patient portion — statements, plans, assistance, agency placement — belongs to Patient Billing & Collections.

- 42 CFR § 424.44 — Time limits for filing claims (opens in a new tab)
One of the two clocks that decide when an aged claim stops being recoverable. It runs from the date of service, so a claim is already spending it before it reaches the first aging bucket.
- 42 CFR § 405.942 — Time frame for filing a request for a redetermination (opens in a new tab)
The other clock. It runs from receipt of the initial determination rather than the date of service, which is why an account's age says nothing on its own about how much appeal time is left.
