How to Reduce Days in A/R: A Practical Guide for Medical Practices
If your days in accounts receivable are creeping past 40, cash is trapped and something upstream is broken. Here are the 2025 benchmarks, what actually drives A/R days up, and a step-by-step plan to bring them down.
Days in accounts receivable is the single clearest read on your revenue cycle's health. It answers one question every practice owner cares about: how long does it take to turn care into cash? When that number climbs, it's rarely one problem — it's a chain of small upstream leaks. Here's how to find and fix them.
- <30–35 — high performers
- 31–40 — acceptable (MGMA / AAFP)
- >50 — significant cash-flow concern
- <5% denial rate (<3% best-in-class)
Know your number first
Calculate days in A/R by dividing current receivables by average daily charges. Track it monthly at minimum — weekly if it's elevated. A single number hides the story, so always pair it with an aging report: the goal is to keep the bulk of A/R in the 0–30 day bucket and starve the 90+ column.
What actually drives A/R up
- Front-end errors. About half of denials come from eligibility, demographic, and authorization mistakes — eligibility alone is ~22% of preventable denials.
- Slow claim submission. Every day a clean claim sits unsubmitted is a day added to A/R.
- Weak denial follow-up. Denied claims that aren't reworked quickly age into the danger zone.
- Rising patient balances. Uncollected patient responsibility is one of the fastest-growing slices of aged A/R.
You don't lower A/R days at the collections end. You lower them at the front desk, the coder's screen, and the clearinghouse.
The reduction plan
- Verify eligibility and benefits in real time before every visit.
- Scrub claims for coding and data errors before submission — aim for a 95%+ clean claim rate.
- Submit daily; don't batch claims into weekly runs.
- Work denials within days, not weeks, using the specific denial reason.
- Collect patient responsibility at the point of service.
- Review the aging report weekly and attack the oldest, largest balances first.
Work the aging buckets relentlessly
A/R follow-up is where good practices separate from average ones. Prioritize by dollar value and age, escalate underpayments and no-response claims, and never let a payer's silence become your write-off. This disciplined back-end work is the core of professional revenue cycle management and denial management.

The bottom line
Days in A/R is a lagging indicator of a hundred upstream decisions. Fix eligibility and coding at the front, submit fast, work denials hard, and collect from patients at the desk — and the number falls on its own. Want a data-backed diagnosis? Start with a free billing audit.

Frequently asked questions
High performers keep days in A/R under 30–35; 31–40 is generally acceptable per MGMA and AAFP norms; and over 50 signals real cash-flow trouble. The goal is to keep most of your receivables in the 0–30 day bucket.
Divide your total current accounts receivable by your average daily charges (total charges over a period divided by the number of days in that period). The result is the average number of days it takes to collect.
Fix the front end. Roughly half of denials trace to eligibility, demographic, and authorization errors — with eligibility alone driving about 22% of preventable denials. Cleaner claims out the door means faster payment in.
Under 5% is healthy and under 3% is best-in-class. High denial rates are one of the biggest hidden causes of rising A/R days.
