The slow cash flow is usually realized by most of the facilities when payroll time comes and there is not enough cash around. As per a survey conducted by Premier on national hospitals, around 15% of the claims that get filed with the private insurers are denied, and 54.3 percent of the denial claims end up getting reversed. The process of each round of review takes 45 to 60 days, and on average, there were three rounds done by providers.
According to HFM guidance, good days in accounts receivable should be between 30 to 40 days; however, many practices are well beyond that figure. This guide explains how to reduce AR days in medical billing through proper front-end handling, effective denial management, aged balance follow-ups, and accurate payment posting. It is based on federal guidelines and surveys. Each point in the guide offers specific strategies that a billing lead can implement immediately.

What Accounts Receivable Days Reveal About Your Revenue Cycle
Formula for calculating accounts receivable days; calculate the total of outstanding receivables divided by the average daily charges. It denotes how long the earned income takes to become money. Assuming a dental office has a process of billing that earns it $10,000 each day, if the days are 45, it has $450,000 of outstanding receivables; while if the days are 30, it has $300,000 of outstanding receivables. This additional $150,000 can be used to pay off expenses.
The benchmarks provide context for the number. Guidance from industry literature indicates that anything between 30 to 40 is considered optimal, while a number greater than 50 often indicates problems with claim processing, follow-up, or denials.
Accounts receivable in the healthcare setting does not consist of one pot of money. It has payer AR, patient AR, and also AR from claims that are under appeal. The aging and required action for each are different. It is best to analyze each separately rather than monitoring just one combined figure that may mask the truth.
Why Aging Balances Are Harder to Collect Every Week
Older accounts are depreciating very fast. Medicare normally demands claims to be filed within 1 year of service date, while other commercial insurance usually gives even shorter time for submission. The aging of the bill for the medical charge will be divided according to the age ranges of the outstanding bills such as 0-30 days, 31-60 days, 61-90 days, 91-120 days and more than 120 days. The average percent of outstanding bills which were aged 120 days and above in the nation-wide group practice benchmark was 13.54 percent.
The collectability rate will decrease as the account ages due to the reason that the contacts will become stale, the appeals period will expire, and the staff will shift their attention towards other matters. In addition, an appeal for the Medicare redetermination should be done within 120 days of the first decision. Furthermore, hospitals have claimed that the Medicare Advantage denials drove balances over 90 days to 27.1-46.7 percent of outstanding balances, almost twice more than usual goals.
Where Payer Behavior Adds Days You Did Not Cause
There are some delays that are beyond your control. Federal guidelines provide for 14-day delays before payment for clean electronic claims and 27 days for paper claims under Medicare. An investigation by a federal inspector general into Medicare Advantage found that 13 percent of prior authorization denials and 18 percent of payment denials were covered under Medicare criteria, which would have justified approval of those procedures. Survey data from hospitals revealed initial denial rates of 16.7 percent for Medicaid, 15.7 percent for Medicare Advantage, and 8.4 percent for traditional Medicare.
Prior authorization creates its own form of resistance. A survey of doctors nationwide found that on average, doctors’ offices fill out 39 prior authorization forms each week, with 93 percent of doctors experiencing delays in care due to this process. In 2026, federal regulations took effect that compel Medicare Advantage and other regulated payers to make decisions within 7 days for nonurgent requests and 72 hours for urgent ones. Having this information in hand will help your team plan their follow-up dates accordingly.
Front End Steps That Shorten the Payment Cycle
Most slow payments begin before the patient leaves the waiting room. Accurate coverage checks, approved authorizations, and complete charge details decide whether a claim pays on first submission. Strong front end habits remove rework, shorten collection time, and protect every later billing step. Outsourcing medical billing services allows healthcare providers to delegate billing operations to experienced professionals while reducing administrative workload and improving payment management.
Verify Coverage Before Every Visit
Changes in coverage happen without warning, and inactivity in the insurance policy is one of the most avoidable grounds for denial. establishes that the client’s policy is active, has outstanding deductible, copay, and referral information before the scheduled visit. It is important to document the response date and claim number to provide grounds for future arguments.
Secure Approvals for Planned Services
The prior authorization services monitor procedures that require prior approval, submit necessary documentation, and follow up on each request till a final decision is made. Note down the approval number, number of units approved, and expiration date. Denials are common where the visit does not fall within the authorized period. Data collected from the hospital reveals that 3.2 percent of all denied claims were previously preapproved.
Capture Demographics Exactly
Incorrectly spelled names, incorrect birth dates, or incorrect policy numbers result in denials that never make it to the adjudication stage. Always ask the patients for their photo ID and insurance card each time you see them. Always scan the front and back, establish subscriber relations, and have the information repeated back to you by the patient.
Enter Charges Within Two Days
Every idle day between the visit and the claim is a day of revenue waiting. A useful goal is to release charges within 24 to 48 hours of the visit, with same day entry for procedures. Assign one person to review unfinished notes daily. Faster charge entry lowers days in accounts receivable even before payers respond.
Match Codes to Documentation
The validity of a statement depends on the note that accompanies it. Proper coding ensures that the correct diagnosis and procedure codes are provided only through proper documentation. Ask clinicians to complete notes the same day. Regular coding reviews catch patterns such as unbundled services or missing laterality before a payer does. Medical coding services convert patient diagnoses, procedures, and treatments into standardized medical codes to support correct billing, claims processing, and reimbursement.
Review Claims Before Release
A short internal review catches missing fields, mismatched modifiers, and invalid payer identifiers. Industry guidance commonly targets a first pass acceptance rate of 95 percent or higher. Track rejected claims by reason each week and fix the source, not just the claim. Every corrected root cause removes future resubmissions and the days they add.
Send Claims Daily and Confirm Receipt
Submit claims every day rather than once a week, using the preferred electronic method of each payer, since the earliest Medicare payment for an electronic claim is in 14 days. Verify acknowledgment reports within 48 hours to ensure that the rejected claim does not go unnoticed. An unheard claim will never become payable but will remain written off.
Expert Insight: Ask the front desk to keep an eye on one figure for a month: the percentage of encounters with pre-verified eligibility and approval prior to admission. The groups that monitor this information every day will find out that most issues arise from a small set of payers.
Denial Management That Recovers Revenue Faster
Denials turn a routine claim into weeks of extra work. Sorting them by cause, correcting them quickly, and blocking repeat errors protects cash flow and shrinks aging buckets. Disciplined denial handling is the largest single lever for teams trying to improve healthcare collections.
Read Every Denial Code Correctly
Remittance advice carries claim adjustment reason codes and remark codes that explain the payer’s decision. Staff who read them precisely can tell a fixable data error from a true coverage dispute. Build a short reference sheet for the twenty most frequent codes in your practice. Answers arrive faster when the team knows what each code truly demands.
Sort Denials by Root Cause
Group denials into registration, authorization, coding, documentation, and payer error. Medical billing denial management improves when the team studies causes instead of chasing single claims. If half of your denials share one reason, one training session or one payer conversation can remove a large share of future workload. Review the ranking every month.
Work High Value Claims First
Hospital survey data shows the average denial is tied to charges of $14,000 or more, so value matters. Rank the worklist by balance, appeal deadline, and payer speed. A single high value claim recovered this week helps more than ten small balances reviewed next month. Reserve senior staff for complex clinical appeals.
Respect Appeal Deadlines
Deadlines vary based on the payer, and failure to meet the deadline means the end of the discussion. The deadlines for redetermination of Medicare denials are 120 days from the date of the denial, while commercial payers have between 60 days to 180 days to contest. Calendar the deadline from the date of receipt of the denial notice.
Appeal More Often
Hospital survey data shows 54.3 percent of private payer denials were eventually overturned, and a separate hospital association survey found half of appealed initial denials succeeded. A national health policy analysis of marketplace plans found that enrollees appeal only a tiny fraction of denials. Providers that appeal consistently recover revenue others abandon. Set a rule that no valid denial closes without review.
Bring in Support When Volume Grows
With denial management services, practices will have the luxury of having an assigned team to code the denial cases, file appeals, and analyze trends in payers. It would be wise to seek external support if denials are greater than 10 percent of the total claims or if the appeals are pending for longer than two weeks.
Prevent Repeat Denials
Every resolved denial should produce a correction upstream. Update payer rule sheets, retrain staff, and adjust registration scripts based on what the denial revealed. Share monthly results with clinicians so documentation habits improve. Practices that close this loop see denial counts fall steadily, which means fewer claims entering aging buckets and less rework.
AR Follow Up and Collection Strategies
Even clean claims stall without steady attention. A disciplined routine defines who calls which payer, when, and what result to record. Sound AR management in medical billing relies on accounts receivable collection strategies that keep balances moving toward payment before they age into the buckets hardest to recover.
Build a Priority Worklist
Sort open balances by amount, age, and payer responsiveness instead of alphabetical order. Medical billing AR follow up works best when the highest recoverable claims appear at the top each morning. Refresh the list daily and assign ownership by payer so one person learns each payer’s habits. Ownership shortens conversations and prevents duplicate calls.
Set a Contact Schedule
Check your claim status around 14 days after you submitted it, and then at 10 to 14-day intervals until completion. Note the date, representative name, reference number, and next step promised by the payer. Escalate the case to your superior once a payer commits to take action twice but fails. A timetable in writing ensures that follow up becomes systematic.
Assign Older Balances to Dedicated Callers
AR Management Services bring trained callers and structured reporting to older balances that in house staff cannot reach. Practices often assign claims older than 60 days to this group while their own team handles current work. Ask for weekly reports showing balances touched, promised payments, and results, so accountability stays visible.
Check for Underpayments
Paid does not always mean paid correctly. Compare each remittance against the contract fee schedule and flag differences. Under the No Surprises Act, disputes over certain out of network payments begin with a 30 business day open negotiation period before independent dispute resolution. Recovering underpaid amounts improves collections without adding a single new visit.
Communicate Patient Balances Clearly
The average deductible for individual coverage was $1,735 in 2023, so the balances have become much higher than before. Set expectations upfront, collect copayments at check-in, and send a statement within days. Make payment arrangements sooner rather than later. Using plain language and different payment options will increase collections on balances before aging.
Separate Payer and Patient Accounts
Patient balances rarely need the same steps as payer balances. Once insurance has paid, move the remainder to a patient statement cycle promptly. Track secondary insurance claims separately so they do not sit unnoticed. Clear separation keeps aging reports honest and shows where each dollar is truly waiting.
Decide When to Write Off
Set written policies for small balance adjustments, timely filing losses, and referral to collections. Review write offs monthly by reason code to find process failures. Effort should follow the probability of payment, so stop spending hours on balances that cannot be recovered. Write off decisions should be documented, since they can improve the days figure without improving performance.
Practice Tip: Have a weekly huddle for 15 minutes every week with three simple questions to ask; what payers are lagging behind, what are the new denial reasons, and what balances will exceed 90 days the following week. This is more effective in identifying problems early and keeping everyone focused.
Payment Posting and Reporting Discipline
Late postings and wrong postings make it impossible to know the actual condition of the receivables. Posting that is done correctly and the proper generation of reports help decision-makers have an accurate representation of AR management in healthcare facilities.
Post Payments the Day They Arrive
Same-day posting ensures that all the accounts are accurate and enables follow-up personnel to know what is still outstanding. Medical billing payment posting services involve linking each remittance to the claim and accounting for the allowed amounts and contract adjustment. A delay of just one week may lead to people chasing payments for claims that have been paid long ago.
Read Electronic Remittance Advice Fully
Remittance advice that is sent electronically should be in the standard form as prescribed by the federal government. You need to review the adjustments, patient responsibility, and denial codes rather than just the payment amount. It is only at the line level that you will notice partial denials, which cannot be seen from the totals.
Reconcile Deposits to Postings
Match bank deposits and electronic funds transfers to posted batches every day. Differences point to missed payments, wrongly applied funds, or takebacks from payers. Reconciliation also detects duplicate postings that inflate collections. A clean match between deposits and posted cash gives credibility to every report built on top of it.
Handle Takebacks and Refunds Promptly
Funds can be recouped through audits or COB checks. Note any takebacks when they occur, and open the account back up so that the balance appears once again. Send any credit balances back within the time specified in the payer contracts and state guidelines. This helps avoid fines and ensures accuracy of the aging report.
Review the Aging Report Weekly
Review the aging report by payer, by provider, and by age bucket. Look for a payer whose 61 to 90 day bucket is growing, or a provider whose claims stall in coding. Weekly review catches trends within days. Monthly review catches them after cash has already been lost.
Track a Small Set of Measures
Focus on days in accounts receivable, the percentage over 90 days, first pass acceptance rate, denial rate, and net collection rate. Published guidance often targets under 20 percent of balances beyond 90 days and net collections above 95 percent. Too many metrics blur attention, while a few measures share weekly drive action.
Bill Secondary Coverage Quickly
When a patient has two plans, the primary remittance triggers the secondary claim. Delay here leaves a balance that looks like patient debt while insurance still owes. Set a rule to file secondary claims within two days of primary posting. Attach the primary explanation of benefits exactly as the second payer requires.
Building a Sustainable Plan to Halve AR Days
Reducing the time of receivables by half requires measurement, assignment of ownership, and regular review instead of an occasional clean-up. How to decrease the days of receivables becomes much easier to learn if you make a written plan with targets by payer, weekly review, and staffing adjustments depending on volume.
Measure Your Starting Point
Record current days in accounts receivable, the percentage over 90 days, denial rate, and average time from visit to claim. Use ninety days of data to smooth spikes. Without a baseline, improvement is a guess. If your figure is 60 today, a target of 30 sets a clear finish line and a quarterly path.
Set Targets by Payer
One target for every payer ignores real differences. Medicare pays predictably, Medicaid denies more often, and commercial contracts vary widely. Set separate goals for days, denial rate, and appeal turnaround for each major payer. Payer level targets show exactly where effort creates the most improvement.
Match Staffing to Workload
Follow up gets neglected when the same person also handles the front desk. Estimate how many claims each biller can work per day, then compare that with your open claim count. If balances age faster than staff can touch them, add capacity or outsource part of the work. Understaffing is a hidden source of long receivable time.
Protect Compliance While Speeding Up
Faster collection never justifies shortcuts, and practices that outsource should confirm audit habits, privacy safeguards, and coding accuracy. Read what happens if your billing company is not compliant to understand the penalties and repayment risks that follow weak controls before you sign any agreement.
Weigh the Return on Outsourcing
Compare the fully loaded cost of in house billing, including salaries, benefits, training, and turnover, with a percentage of collections. The True ROI of outsourcing medical billing explains how to measure savings, faster cash, and reduced denials fairly. Decisions based on measured return hold up better than decisions based on price alone.
Create a 90 Day Improvement Calendar
Month 1, correct front-end testing and initiate priority list. Month 2, improve denial and appeal process. Month 3, analyze payer goals and reporting. Using a schedule with named accountabilities will keep the momentum going and help you celebrate successes, like reducing time by ten days, which inspires employees to maintain their routine.
Review and Adjust Every Quarter
Payers change rules, staff turn over, and specialties shift. Every quarter, compare results against targets, examine new denial patterns, and update procedures. Reset goals once you reach them. Sustained performance comes from repeated small corrections, and a practice that keeps reviewing rarely returns to the long aging that started the effort.
Field Note: Prior to committing to any billing contract, ask for an aging sample from a like practice showing any balances over 90 days per payer. Actual aging samples are far more indicative of the follow-up quality than the sales presentation.

FAQs
What is a good number of AR days in medical billing?
Norms for financial management advice indicate a healthy number of days in accounts receivable range between 30 and 40 days, with excellent performers at 30. Some specialties with complicated payer mix might have a higher number. Note your own trend, benchmark against similar practices, and a score above 50 is a sign of investigation needed.
How long does it take to reduce AR days?
Generally, most practices expect some early movement within 60-90 days after establishing front-end procedures, denial processing and follow-ups are in place. Halving the number generally takes many months as it involves handling of old balances and reviewing cycles take 45-60 days on their own.
What causes high AR days?
Eligibility issues, missing authorization, improper coding, delayed billing, denial management, and follow-up inconsistency are some common reasons. Delays by payers are also another reason. The hospital surveys indicate that around 15 percent of all claims of private payers are initially denied, and with each review cycle, weeks go past without payment.
How often should AR follow up happen?
Monitor the status of the claim after about 14 days of submission and check every 10 to 14 days after that until the claim is resolved. Prioritize claims which are higher in amount and those that are near the deadline for an appeal or filing.
Should a small practice outsource AR follow up?
Outsourcing is the solution to go for in case balances past 60 days continue increasing, denial rates top 10 percent, or employees are unable to cope. The key here is to compare in house full cost with percentage of collections and make sure that the vendor is reporting weekly.
What is the difference between AR days and aging?
Average Days in Accounts Receivable is another average that indicates the length of time it takes to collect receivables. The aging schedule divides the balances according to their age into categories like 0-30 and over 120 days. Average days indicate the speed, whereas categories indicate the location.
