How to Reduce Days in AR: A Practical Guide for Specialty Practices

Published April 21, 2026 · 10 min read · By RCMAXIS Revenue Cycle Team

Days in Accounts Receivable (Days in AR) is one of the most closely watched metrics in medical practice finance — and for good reason. It tells you, on average, how long it takes your practice to collect payment after a service is rendered. For specialty practices operating on thin margins and facing ever-increasing payer complexity, a bloated AR cycle is the difference between a thriving practice and a cash-strapped one.

This guide covers what Days in AR actually measures, why AR balloons in specialty settings, an analysis of AR aging buckets, and eight proven strategies that RCMAXIS uses to bring client AR cycles down to an average of 34 days.

What Is Days in AR — and Why Does It Matter?

Days in AR (also written as Days in A/R or Accounts Receivable Days) measures the average number of days it takes a practice to collect payment from the date of service. The formula is straightforward:

Days in AR = (Total AR Balance ÷ Average Daily Charges)

If your practice bills $500,000 per month and carries $800,000 in total AR, your Days in AR is approximately 48 days — well above the industry benchmark of 40 days for specialty practices.

Why does this matter in dollars and cents? Every extra day in AR represents working capital that cannot be reinvested in staff, equipment, or patient care. A practice billing $6 million annually with Days in AR of 50 versus 35 is effectively carrying $246,000 in extra uncollected receivables at any given time — money that may never be collected as claims age past timely filing limits and payer dispute windows close.

Industry Benchmark: What Is a Good Days in AR?

Benchmarks vary by specialty and payer mix, but the Healthcare Financial Management Association (HFMA) and MGMA both publish consistent guidance:

• Under 35 days — Excellent; top-quartile performance
• 35–40 days — Good; meets industry standard for most specialties
• 41–50 days — Fair; room for meaningful improvement
• 50–60 days — Concerning; likely systemic billing or follow-up issues
• Over 60 days — Critical; revenue is at risk and immediate action is warranted

Specialty practices — particularly those in orthopaedics, neurology, oncology, and pain management — often run higher AR days due to complex coding, frequent prior authorization requirements, and higher rates of insurance disputes. These specialties should target under 45 days while working toward the sub-40 benchmark.

Top Reasons AR Balloons in Specialty Practices

1. High Denial Rates on First Submission

Every denied claim that requires rework adds 15–30 days to the collection cycle. Specialty billing is denial-prone: complex CPT codes, medical necessity requirements, bundling rules, and modifier requirements all create opportunities for first-pass rejections. Practices without a dedicated denial management process see these claims age silently.

2. Slow or Inconsistent Follow-Up on Unpaid Claims

Unpaid claims do not collect themselves. Without a systematic worklist process — typically follow-up beginning at day 25–30 for commercial payers and day 20 for Medicare — claims sit until they cross timely filing limits. Most payers allow only 90–180 days from date of service, and some as few as 60 days for appeal.

3. Credentialing Gaps and Enrollment Delays

A provider who is not yet enrolled with a payer cannot bill that payer — even for services already rendered. Credentialing delays of 60–120 days create an AR backlog before the practice has submitted a single claim. For new providers joining a group, this is one of the most preventable sources of AR inflation. Our credentialing and enrollment services address this directly.

4. Payer Processing Delays and Underpayments

Some payers — particularly certain Medicaid managed care plans and smaller commercial insurers — have structurally slow claims processing. Recognizing which payers in your mix are chronic slow-payers and adjusting follow-up timelines accordingly is essential for managing AR by payer category.

5. Patient Balance Collection Failures

As high-deductible health plans proliferate, patient responsibility has grown to represent 25–30% of practice revenue for many specialties. Practices without effective point-of-service collection processes and patient billing workflows carry large patient AR balances that are significantly harder to collect than insurance AR. The bad debt write-off rate on patient balances over 120 days can exceed 60%.

6. Charge Lag and Delayed Claim Submission

The clock on Days in AR starts at date of service — but AR only appears when a charge is posted. Practices where providers take 3–7 days to submit notes and where billing staff take another 2–3 days to post charges are effectively adding 5–10 days to their AR cycle before a claim is even submitted.

AR Aging Buckets: How to Read Your AR Report

AR aging breaks down your total receivables by how long they have been outstanding. Every practice management system generates this report. Here is what each bucket signals:

A healthy AR aging report has 75–80% of total AR in the 0–60 day buckets. If you find more than 20% of your AR in the 90+ day category, your practice has a systemic collection problem that requires process intervention — not just staff effort.

8 Proven Strategies to Reduce Days in AR

Strategy 1: Submit Clean Claims Within 24–48 Hours of Service

Every day between service and claim submission is a day added to your AR cycle. Implement a process where provider notes are completed same-day or within 24 hours, charges are posted by billing staff within 24 hours of note completion, and claims are submitted electronically within 48 hours of service. This single discipline — which our claims management team enforces rigorously — can reduce Days in AR by 5–8 days alone.

Strategy 2: Run Eligibility Verification Before Every Appointment

Billing a patient under a terminated insurance plan or an incorrect plan ID generates an immediate denial that delays payment by 30–60 days. Real-time eligibility verification — run 24–48 hours before each appointment — prevents the majority of these avoidable rejections.

Strategy 3: Implement a Denial Management Workflow

Denials should be worked within 5 business days of receipt. Assign denial categories to specific staff members, track denial root causes weekly, and measure first-pass resolution rate monthly. Practices that move from reactive denial management to a structured workflow typically see AR days fall by 8–12 days within 90 days.

Strategy 4: Establish a Payer-Specific Follow-Up Calendar

Not all payers process claims on the same timeline. Build a follow-up calendar that triggers outreach at specific intervals for each payer category: commercial payers at day 25, Medicare at day 20, Medicaid at day 30. Automated worklist generation in your PM system should drive this — staff should not be manually hunting for unpaid claims.

Strategy 5: Collect Patient Balances at Point of Service

Patient AR is the most expensive AR to collect. Collect copays and known deductible amounts at check-in. For elective procedures, collect the patient's estimated responsibility at scheduling. Patient balances collected at the time of service have a collection rate near 95%; balances billed after the fact drop to 70% at 30 days and below 40% at 90 days.

Strategy 6: Address Credentialing and Enrollment Proactively

Begin credentialing new providers and re-credentialing expiring providers at least 90 days before their effective date. Billing for a provider who is not yet enrolled with a payer results in rejections that must be re-billed retroactively — often creating a 60–90 day gap in collections for that provider's claims. Our provider credentialing team starts the enrollment process as early as possible to prevent these gaps.

Strategy 7: Monitor and Renegotiate Payer Contracts

Chronic underpayments from specific payers artificially inflate AR when your billing system holds balances open for secondary billing or appeal. Identifying payers that consistently pay below contracted rates — and having those contracts audited — can resolve large AR buckets that exist not because of billing errors but because of systematic payer underpayment. Our revenue recovery team conducts payer contract audits as part of this process.

Strategy 8: Partner With an RCM Company That Manages AR Proactively

The most effective lever most specialty practices have for reducing AR days is working with a revenue cycle management partner who treats AR management as a primary function — not an afterthought. This means daily worklist management, real-time denial tracking, and AR reporting delivered to practice leadership weekly.

How RCMAXIS Clients Achieve a 34-Day AR Cycle

Across our client base of specialty practices, RCMAXIS clients average a 34-day AR cycle — well below the industry benchmark of 40 days. We achieve this through:

• Same-day charge posting and 48-hour claim submission targets enforced through internal SLAs
• Payer-specific follow-up calendars built into our workflow management system
• Daily denial management with root-cause tracking and monthly reporting to practice leadership
• Proactive credentialing management that prevents enrollment gaps from impacting billing
• Real-time AR aging dashboards shared with practice administrators weekly
• Patient statement cycles and balance collection processes that keep patient AR below 10% of total receivables

For a specialty practice billing $500,000 per month, moving from 50-day AR to 34-day AR represents approximately $240,000 in accelerated cash flow — and that is before accounting for the additional revenue recovered from denials that previously aged to write-off.
