How to Reduce Accounts Receivable Days in Your Medical Practice

Accounts receivable days (A/R days) measure how long it takes your practice to convert a claim into cash. The healthcare industry benchmark is 35-40 days; most practices sit at 45-65 days. Every extra day outstanding is cash you cannot reinvest in staff, equipment, or operations. High A/R days almost always reflect one or more of these failures: slow claim submission, preventable denials, poor patient collections, or lack of follow-up. This guide walks you through the operational and billing fixes that reduce A/R days by 10-20 days within 90 days.

Measure your baseline A/R days accurately

You cannot improve what you do not measure. Calculate your A/R days using this formula: (Accounts Receivable Balance / Average Daily Charge) = A/R Days. For example, if your A/R balance is $300,000 and your average daily charges are $8,000, you have 37.5 A/R days.

Run this calculation monthly, not quarterly. Most practices discover they are 8-15 days worse than they think because they exclude write-offs, denials, and aging balances in their informal estimates. Use your billing software's aging report (0-30, 31-60, 61-90, 90+ days) to segment claims. If more than 20% of A/R is over 90 days, you have a systemic problem: either denials are not being appealed, or patient balances are not being collected.

Track the percentage of claims paid within 30 days by payer. Medicare typically pays in 14-21 days; Medicaid varies by state (21-45 days); commercial plans vary widely (15-45 days). If a payer is consistently outside its window, escalate to your clearinghouse or payer relations contact.

• Formula: A/R Balance / Daily Average Charges
• Run calculation monthly, not quarterly
• Segment A/R by aging bucket (0-30, 31-60, 61-90, 90+)
• Compare actual payment windows by payer to contract terms

Eliminate claim submission delays

Most claims should leave your practice within 1-2 business days of service. Delays typically happen at three points: (1) charge capture is slow or incomplete, (2) claims are held for batch processing instead of real-time submission, or (3) verification and coding errors are caught after the claim is supposedly ready.

Set a hard deadline: all charges and documentation must be entered the same day as service, or by 5 p.m. the next business day at latest. If your EHR does not enforce this rule, your office manager or billing supervisor must audit the charge log daily and escalate missing charges to the clinical team.

Use a claims submission report. Every day, run a report showing claims submitted, number of claims, and total dollar amount. Most claims management systems allow submission by payer. If Medicare claims are sitting in a staging queue for more than 24 hours, investigate why. Common culprits: missing NPI, invalid ICD-10 code, or claims being held for secondary insurance verification.

• Charge all services same day or next business day by 5 p.m.
• Submit claims to payers daily, not in weekly batches
• Run daily claims submission report: volume and dollar amount
• Flag any claim held more than 24 hours; investigate root cause

Attack preventable claim denials and rejections

Denials and rejections reset your A/R clock. A claim denied for invalid ICD-10 code is resubmitted, pushing payment out another 2-3 weeks. Rejections (claims never accepted by the payer) are even worse—they indicate a technical error that stops the claim before adjudication.

Categorize denials by reason for three months. Use your EOB (Explanation of Benefits) data or denial management report. The top reasons in most practices are: (1) medical necessity dispute (insurance denies the code combination), (2) eligibility issues (patient ineligible on date of service), (3) missing or invalid authorization, (4) coding errors (wrong ICD-10 or CPT modifier), and (5) patient responsibility not verified. Fix the top three reasons first.

For eligibility denials: verify insurance benefits before every appointment. This is foundational. Use real-time eligibility checks (most clearinghouses offer this). Train front desk staff to document the effective date, termination date, and copay/deductible at check-in. Denials for 'coverage ended' are 100% preventable.

For medical necessity denials: audit your documentation. If a payer denies a service as not medically necessary, review the clinical note. Is the indication for treatment clearly stated? Does the note justify the number of units or the level of service billed? Work with your physicians to tighten documentation on high-denial services.

• Track denials and rejections by reason for 90 days
• Implement real-time eligibility verification before every visit
• Audit clinical notes for medical necessity denials
• Document patient authorization and secondary insurance at check-in
• Appeal all denials within payer appeal window (typically 90-180 days)

Strengthen patient collections and financial counseling

Patient responsibility (copays, coinsurance, deductibles) often sits unpaid for months because staff do not collect it at visit or follow up afterward. This is a leak in both A/R days and net revenue. Implement a rule: collect copay at check-in, not after the visit. If copay is not paid, the appointment does not start.

For deductibles and coinsurance due after insurance pays: send an invoice within 48 hours of the EOB posting. Do not wait. Include a clear breakdown: what was billed, what insurance paid, what patient owes, and due date. Most practices send statements monthly, which costs 15-30 days in A/R time.

Offer a payment plan for balances over $500. Many patients will pay if given a 3-6 month option instead of facing a large lump-sum bill. Use a patient portal or automated payment system (not checks) to reduce friction. Automate reminders: first reminder at 30 days, second at 60 days, third via phone or collections at 90 days.

Train clinical and front desk staff on financial counseling. If a patient has a $2,000 deductible, the financial counselor should explain this before the procedure, not surprise the patient with a bill afterward. Surprised patients do not pay, or pay slowly.

• Collect copays at check-in, not after visit
• Invoice patient responsibility within 48 hours of EOB posting
• Offer payment plans for balances over $500
• Use automated reminders at 30, 60, and 90 days
• Conduct pre-visit financial counseling for high-deductible patients

Implement systematic follow-up for aged A/R

Claims over 60 days old require hands-on follow-up. A claim that was submitted but not paid within 30 days of EOB posting likely has a problem that will not resolve itself. Create a weekly follow-up routine: pull all claims 31-60 days old and 61-90 days old. Call or email the payer's provider line. Ask: has the claim been paid, is it pending, or was it denied? Log the response.

Use a follow-up log (spreadsheet or built-in feature in your billing software) that tracks: claim number, payer, date of service, submission date, expected payment date, follow-up date, payer's response, and action taken. This prevents duplicate follow-up calls and keeps the team accountable.

For patient balances over 90 days: transfer to collections or an in-house collections protocol. Many practices keep aged patient balances in A/R indefinitely and inflate their A/R days. If a patient balance is uncollectible, write it off. If it is collectible, pursue it. Do not let it sit.

Set a policy: claims over 120 days old must have a documented reason (pending appeal, patient dispute, awaiting secondary insurance, write-off) and an assigned owner. Without ownership, no one follows up.

• Review aged A/R weekly; follow up on claims 31+ days old
• Call payer for all claims 31-60 days old
• Log all follow-up calls and payer responses in a centralized log
• Transfer patient balances over 90 days to collections or write off
• Assign an owner to every claim over 120 days old

Optimize your claim scrubbing and automation

Most billing software includes pre-submission claim scrubbing: automated checks for missing fields, invalid codes, duplicate claims, and payer-specific requirements. Enable all scrubbing rules and do not override them. If a claim fails a scrub rule, fix it before submission. Do not send broken claims and hope payers ignore the error.

Common scrubbing errors that delay payment: (1) missing or invalid NPI or tax ID, (2) procedure code (CPT) without required modifiers, (3) ICD-10 code not valid for the date of service (outdated code), (4) procedure billed to the wrong place of service code, (5) patient name or DOB mismatch. Run a monthly audit of override rates. If your team is overriding scrub errors more than 2-3% of the time, your coders or billing staff need retraining.

Automate the EOB posting workflow. Manual EOB posting is slow and error-prone. Use a solution that reads EOBs automatically, applies the payment to the correct claim, and creates an aging report of remaining patient responsibility. This cuts 5-7 days from your posting cycle.

• Enable all pre-submission claim scrubbing rules
• Do not override scrubbing errors; fix the claim
• Audit monthly override rates; target less than 2% of submissions
• Automate EOB posting and posting accuracy reporting

Set targets and monitor progress monthly

A/R days improvement does not happen by accident. Set a target: reduce A/R days from 50 to 40 in 90 days. Break this into monthly milestones: month 1, reduce to 48 days; month 2, to 44 days; month 3, to 40 days. Assign a point person (billing manager or office manager) to own this metric.

Monitor these supporting metrics weekly or bi-weekly: (1) percentage of claims submitted within 24 hours of charge entry, (2) percentage of claims paid within 30 days, (3) denial rate (percentage of submitted claims denied), (4) average days to appeal and resubmit a denial, (5) percentage of copays collected at visit, and (6) aged A/R over 90 days as a percentage of total A/R.

Share progress with clinical and administrative leadership monthly. Practices that make A/R days a visible, tracked metric improve faster than those that do not. If the denial rate jumps in month 2, investigate immediately. If claims are not being submitted within 24 hours, identify the bottleneck and fix it.

• Set a target A/R days reduction over 90 days
• Create monthly milestones and assign an owner
• Track supporting metrics weekly: submission rate, payment rate, denial rate, copay collection
• Review progress monthly with leadership and clinical team
