How to Reduce Days in Accounts Receivable in Healthcare (2025 Playbook)

Every day between service delivery and claim submission is a day added to AR. Best practice is claim submission within 24–48 hours of service. Claims with errors are either rejected (never received) or denied (received and rejected) — both restart the clock. A single field error (wrong NPI, invalid modifier) can add 30+ days to your AR cycle.

Denied claims that sit unworked for 30+ days are the single largest contributor to high AR days in most practices. Without a denial work queue prioritized by balance size and denial date, billers work through claims reactively and valuable balances approach timely filing deadlines.

Patient responsibility portions that aren't collected promptly inflate your AR just as much as unresolved insurance claims. A patient balance that sits for 60 days while you wait for a check in the mail adds those 60 days to your average — even though insurance paid their portion on day 18.

Treating a patient whose insurance is inactive, whose referral has expired, or whose benefits don't cover the service creates a guaranteed denial that adds 30–90 days of rework. Real-time eligibility verification before every appointment eliminates this entire category.

Payers occasionally lose claims, process them into a black hole, or apply incorrect contract rates. Without systematic follow-up at 21 days for commercial and 14 days for Medicare, these problems age silently. Proactive outreach surfaces them before they become 90-day problems.

Contractual adjustments that haven't been posted yet inflate gross AR artificially and distort your AR days calculation. Timely posting of EOBs and systematic processing of contractual write-offs keeps your AR picture accurate and actionable.

Pull a complete AR aging report by payer and by bucket. Calculate your current AR days. Identify which buckets are growing (problem areas) vs. stable. Determine your top 5 denial reason codes by dollar volume. This baseline will be your before-and-after comparison.

Audit your claims submission lag. How many days from date of service to submission date? Set a target: all claims submitted within 48 hours. Implement clearinghouse-level claim scrubbing. Create a daily submission confirmation report — every claim sent, every rejection received. Train billing staff to work rejections same-day.

Create a priority-based denial work queue sorted by: (1) claims approaching timely filing deadlines, (2) highest balance amount, (3) oldest date of service. Assign ownership. Set a target: no denial sits unworked for more than 5 business days. Track your denial rework rate weekly.

Deploy automated patient billing — multi-channel (email, SMS, paper) with embedded payment links. The goal is to reduce the lag between EOB posting and first patient touchpoint from 14–21 days to 1–3 days. This alone typically reduces patient AR days by 15–20 days.

Build a calendar-based payer follow-up process. Commercial claims with no response at 21 days get a status call. Medicare at 14 days. Medicaid at 21 days (varies by state). Use payer portals where available — it's faster than phone. Document every follow-up in your PM system.

With your new processes in place for current claims, turn attention to the 60+ day backlog. Segment by insurance vs. patient. For insurance AR, pull payer-by-payer and work top balances first. For patient AR, deploy your full collection sequence immediately on all 60+ day balances.

At 90 days, recalculate your AR days and compare against baseline. Identify which interventions moved the needle most. Double down on those. Identify remaining problem areas and address their root causes. Set a quarterly AR review cadence going forward.
