Days in AR is the metric that tells you whether your revenue cycle is actually working. Here's how we take a practice from 45 days to 22.
First, a definition worth being precise about: days in AR is your total outstanding receivables divided by average daily charges. It tells you, on average, how long your money sits unpaid.
Under 30 days is good. Over 45 is a problem. Over 60 means something is structurally broken.
Step 1: Stop the bleeding at the front end
You cannot fix AR by working AR harder. Most of what's sitting in your AR shouldn't have been there in the first place.
Before touching the backlog, fix the intake: verify eligibility close to the visit, confirm prior auth is in hand (not "requested"), and collect patient responsibility upfront where possible.
Step 2: Submit same-day, always
If claims are batched every 3 days, you've added 3 days to every single claim before it even leaves the building. Multiply that across a year. Same-day submission is the cheapest AR reduction available.
Step 3: Work AR by recovery probability, not by age
This is the change that moves the number most, and almost nobody does it.
The standard approach is to work the oldest claims first. That feels responsible and is actually backwards: the oldest claims are often the least likely to be recovered. You're spending your best hours on your worst odds.
Prioritize by expected value
Rank every open claim by claim value × probability of recovery. A $2,400 claim at 60 days with a fixable coding error outranks a $180 claim at 120 days with a timely-filing problem.
Your staff has finite hours. Spend them where the dollars are actually recoverable.
Step 4: Categorize denials by root cause, monthly
Every month, sort denials into buckets: eligibility, coding, modifier, prior auth, documentation, timely filing. Then take the largest bucket and fix the process behind it.
Do that for three months and your denial rate falls structurally, not because you appealed better, but because you stopped generating that category.
Step 5: Attack the 90+ bucket separately
Claims over 90 days need a different strategy: escalation, payer rep contact, and a hard decision about write-offs. Mixing them into daily AR work means they never get the escalation they need, and they quietly age into worthlessness.
What the math looks like
A worked example
Take a practice billing $400,000/month with 45 days in AR and a 15% denial rate.
Getting AR from 45 days to 22 releases roughly $300,000 of cash that was previously sitting unpaid: money you already earned, just stuck.
Cutting denials from 15% to 6% on 1,000 claims/month means 90 fewer denials monthly. At a realistic blended cost of ~$118 each (see our post on the true cost of a denial), that's over $10,000/month in recovered value.
This is an illustration of the arithmetic, not a specific client. Your numbers depend on your payer mix, specialty and claim volume, which is exactly what a free audit is for.
None of those five steps is clever. They're just done consistently, on every claim, which is exactly the kind of consistency software is good at enforcing.
