Healthcare accounts receivable: How to reduce AR days and collect faster

Your billing manager reports that accounts receivable are at $420,000. You nod. That number has been roughly the same for the past six months, so it feels normal. But $420,000 in AR at your collection volume means 52 days of revenue sitting in the pipeline. The industry benchmark is 35 to 40 days. Those 12 extra days represent approximately $97,000 in revenue that should already be in your bank account but is instead aging through your collection cycle, losing value with every week it sits uncollected.

Healthcare accounts receivable is not just a balance sheet line item. It is a real-time measure of how efficiently your practice converts delivered care into collected revenue. High AR days mean slow collections. Slow collections mean cash flow pressure. And cash flow pressure means the practice that is profitable on paper struggles to meet payroll, invest in growth, or build reserves.

Reducing AR days does not require working harder. It requires identifying where claims and patient balances get stuck in the collection pipeline and eliminating the delays at each stage.

Understanding what AR days actually tell you

Days in accounts receivable are calculated by dividing total AR by average daily charges. If your practice carries $420,000 in AR and generates $8,100 in average daily charges, your AR days are 52. That means the average dollar of revenue takes 52 days to convert from a delivered service to collected cash, compared with the MGMA benchmark of 35 to 40 days for well-managed practices.

But the average masks a critical detail. Your AR is not one homogeneous pool. It is a layered portfolio with different collection probabilities at each age. Track your accounts receivable aging distribution monthly to understand which bucket is distorting your overall days figure.

AR aging distribution: targets and collection probability

The five causes of high AR days in medical practices

AR days do not climb because of one large problem. They climb due to multiple small delays that compound throughout the revenue cycle.

1. Slow charge entry and claim submission. Every day between patient visit and claim submission adds a day to AR. A practice that enters charges three to five days after the visit and batches claim submissions weekly adds seven to twelve unnecessary days to every collection cycle. The fix: enter charges within 24 hours and submit claims daily.

2. High denial rates without systematic rework. A 7% denial rate means 7% of your claims enter a secondary collection cycle that adds 30 to 60 days. If denied claims are not worked within 72 hours of receipt, they sit in a queue aging past the window where recovery is most likely. Track the denial rate monthly. Target below 5%. Assign daily denial management to a specific person.

3. Delayed patient billing after insurance adjudication. Once insurance pays its portion, the remaining patient balance must be billed immediately. Practices that wait until the end of the month to generate patient statements add 15 to 25 unnecessary days to the patient collection cycle. Send statements within five business days of insurance payment posting.

4. Inconsistent follow-up on aging claims. Claims in the 30 to 60-day bucket need active follow-up: checking claim status with the payer, identifying whether additional information is needed, and resubmitting if the claim was lost. Without a structured follow-up process, claims sit in "pending" status far longer than necessary. Assign a weekly follow-up on all claims over 30 days.

5. No point-of-service patient collection. Patient responsibility collected at the visit is never entered into AR. A practice that collects copays, deductibles, and estimated coinsurance at check-in reduces patient AR by 30% to 40%. Every dollar not collected at the visit becomes a dollar that takes 60 to 120 days to collect through the billing cycle, if it is collected at all.

A 90-day plan to reduce AR days by 10 or more

Reducing AR days from 50+ to below 40 is achievable within 90 days by simultaneously addressing all five causes. For practices that want to implement this plan without internal accounting headcount to manage the tracking, the guide to outsourcing finance and accounting covers how outsourced controllers build and maintain AR monitoring as a standard monthly deliverable.

Days 1 to 30: fix the front end. Implement same-day charge entry and daily claim submission. Verify insurance eligibility before every visit. Begin collecting estimated patient responsibility at check-in. These changes prevent new AR from entering the pipeline with built-in delays.

Days 1 to 30 (parallel): attack the 90+ bucket. Pull every claim and balance over 90 days. Categorise each one: denied (rework immediately), pending with payer (call for status), patient balance (final notice with payment plan offer), or uncollectable (write off with documentation). Clearing the 90+ bucket reduces total AR immediately and removes balances that are distorting the AR days calculation.

Days 31 to 60: build the denial management workflow. Assign one person to review denials daily. Categorise by reason code. Rework and resubmit within 72 hours. Track denial rate and resolution rate weekly. The goal: no denial sits unworked for more than 14 days.

Days 31 to 60 (parallel): accelerate patient billing. Generate patient statements within 5 days of insurance payment posting, rather than in monthly batches. Add online payment options if not already available. Send text or email payment reminders at 30 days. Offer payment plans proactively for balances over $200.

Days 61 to 90: institutionalise weekly AR review. Every week, review the AR aging report by payer and by aging bucket. Identify any payer with a 30+ day balance that is growing. Follow up on the 10 highest-dollar claims in the 31 to 60-day bucket. Review patient balances approaching 90 days for escalation to phone follow-up or payment plan outreach.

Measuring progress and maintaining gains

Track four metrics weekly during the 90-day improvement period and monthly thereafter.

Total AR days. Your primary metric. Target: below 40. Plot weekly to see the trend.

AR aging distribution. The percentage in each bucket. Target: 80%+ current, less than 10% over 90 days.

Clean claim rate. Percentage of claims that pass through scrubbing without errors on first submission. Target: 95%+. Higher clean claim rates mean fewer delays and denials.

Patient collection rate at the point of service. Percentage of estimated patient responsibility collected at the visit. Target: 70%+. This metric directly reduces the patient AR that is slowest and hardest to collect.

Lower AR days means more than faster cash

Reducing AR days from 52 to 38 not only speeds up cash flow but also improves profitability. It reduces claims aging past collectability (fewer write-offs), reduces staff hours on follow-up (lower billing costs), and produces cleaner financial statements that reflect actual cash position rather than optimistic accrual assumptions.

The medical and healthcare practices with 38-day AR and those with 52-day AR may bill the same amount. But the first collects more, collects faster, and requires less staff effort to do it. The difference is not billing volume. It is the collection infrastructure built around it.

Frequently asked questions

What is a good number of days in accounts receivable for a medical practice?

The MGMA benchmark for a well-managed practice is 35 to 40 days in AR. Below 35 days indicates highly efficient collections. Between 40 and 50 days suggests process delays in at least one stage of the revenue cycle. Above 50 days indicates systemic issues across multiple stages: slow charge entry, high denial rates, delayed patient billing, or insufficient follow-up on aging claims. The aging distribution matters as much as the total. A practice at 42 days with 85% of AR current is healthier than one at 38 days with 20% of AR over 90 days.

How do I calculate days in accounts receivable?

Divide total accounts receivable by average daily charges. Average daily charges equal total charges for the period divided by the number of days in the period. If your practice has $420,000 in total AR and generates $8,100 in average daily charges ($2.43 million annually), AR days are 52. Calculate this monthly using the same methodology each time. Inconsistent calculation methods, such as using collections instead of charges in the denominator, produce results that cannot be compared to industry benchmarks.

What causes high AR days in a medical practice?

High AR days are almost always caused by multiple compounding delays rather than one large failure. The five most common causes are: slow charge entry and claim submission (each day of delay adds a day to AR), high denial rates without systematic rework (denied claims add 30 to 60 days to the collection cycle), delayed patient billing after insurance adjudication (waiting until month-end adds 15 to 25 unnecessary days), inconsistent follow-up on 30 to 60-day claims, and no point-of-service patient collection (every dollar not collected at the visit takes 60 to 120 days to collect through the billing cycle).

What does it mean if more than 15% of my AR is over 90 days?

It signals a systemic collection failure, not a temporary cash flow issue. At 90+ days, collection probability on patient balances falls below 25%. Insurance claims over 90 days may be approaching timely filing limits for appeals, permanently eliminating the ability to recover them. A reading above 15% in the 90+ bucket means the practice is routinely allowing claims and balances to age past the point where recovery is realistic. The immediate action is to pull every balance over 90 days, categorise each one (denied, pending, patient balance, or uncollectable), and either rework or write off with documentation within 30 days.

How quickly can a practice realistically reduce AR days?

A practice that simultaneously addresses all five causes of high AR days can reduce from 50+ days to below 40 within 90 days. The fastest gains come in the first 30 days from two sources: implementing same-day charge entry and daily claim submission (which prevents new AR from entering with built-in delays) and aggressively clearing the 90+ bucket (which removes aged balances that inflate the total AR figure). The remaining reduction comes from building denial management workflows, accelerating patient billing, and institutionalising weekly AR review in days 31 to 90.
