Medical practice collections: How to collect more of what you've already earned

Your practice billed $2.8 million last year. After contractual adjustments, the expected collectible amount was $1.85 million. You actually collected $1.72 million. That $130,000 gap between what you were owed and what you received is not a billing problem. It is a collection problem. The services were delivered. The claims were submitted. The money was earned. But somewhere between adjudication and deposit, 7% of your expected revenue disappeared into denied claims that were never reworked, patient balances that were never pursued, and insurance underpayments that were never challenged.

Medical practice collections is not about billing more aggressively. It is about building systematic processes that capture the revenue you have already earned. The most effective collection improvements do not require seeing more patients or renegotiating payer contracts. They require closing the gaps where earned revenue leaks out of the system.

Where collections fall apart in a medical practice

Revenue leaks through four predictable gaps. Identifying which ones are active in your practice is the first step to closing them.

Gap 1: denied claims that are never reworked. The average medical practice has a denial rate of 5% to 10%. Of those denied claims, industry data shows that 50% to 65% are never resubmitted. On $2.8 million in annual charges with a 7% denial rate, that is $196,000 in denied claims. If 60% are never reworked, $117,600 in potentially recoverable revenue is abandoned every year.

Denials are not random. They cluster around specific reasons: eligibility issues (patient coverage was inactive), authorization failures (prior authorization was not obtained), coding errors (incorrect modifier or diagnosis), and timely filing (claim submitted after the payer's deadline). Tracking denial reasons by category reveals which upstream process is failing. A practice with 40% of denials tied to eligibility has a front desk verification problem, not a billing problem.

Gap 2: patient balances that age past collectability. After insurance pays its portion, the remaining patient responsibility becomes the hardest revenue to collect. The probability of collecting a patient balance drops sharply with time: 95% at 30 days, 75% at 60 days, 50% at 90 days, and less than 25% at 120 days. A practice that waits 45 days to send the first patient statement has already lost a significant portion of its collection probability. Track your accounts receivable aging by payer and by balance age monthly to monitor where patient balances are stalling in the collection cycle.

Gap 3: insurance underpayments that go undetected. Insurance carriers do not always pay the contracted rate. Processing errors, incorrect fee schedule application, and bundling adjustments can result in payments that are 3% to 8% below the contracted amount. If your team posts payments without comparing them to the expected reimbursement for each CPT code, underpayments become invisible. On $1.2 million in annual insurance payments, a 4% underpayment rate amounts to $48,000 in contracted revenue that was not paid.

Gap 4: write-offs that are not reviewed or approved. Many practices allow billing staff to write off small balances (under $25 or $50) without review. Over time, these small write-offs accumulate into a significant revenue loss. A practice writing off 200 balances per month at an average of $18 results in a loss of $43,200 annually. Without a review process, some of those write-offs may represent collectible revenue that was dismissed as not worth pursuing.

Building a collection system that captures earned revenue

Closing each gap requires a specific process, not a general effort to "be better at collections." For practices that want to build this monitoring capability without internal accounting headcount, the guide to outsourcing finance and accounting covers how outsourced controllers build denial tracking, payment posting review, and write-off approval workflows as standard monthly deliverables.

For denied claims: build a daily denial management workflow. Assign one person to review denials the day they are received. Categorize each denial by reason code. Rework and resubmit within 72 hours. Track the denial rate by payer and by reason monthly. Set a target that less than 10% of denied claims remain unworked after 14 days. The fastest-resolving denials are those worked immediately. Denials that have sat in a queue for 2 weeks have significantly lower recovery rates.

For patient balances: collect at the point of service and follow up systematically. Verify insurance benefits before the visit. Calculate the estimated patient responsibility based on the plan's copay, coinsurance, and deductible status. Collect the estimated amount at check-in or check-out. For balances that arise after insurance processing, send the first statement within 5 business days of the payment posting. Follow up at 30 and 60 days. At 90 days, offer a phone call or payment plan. At 120 days, evaluate whether to send to collections or write off.

Point-of-service collection is the single most effective patient collections strategy. Practices that collect consistently at the visit reduce patient accounts receivable by 30% to 40% and eliminate the cost and time of billing those balances after the fact.

For underpayments: compare each EOB to the contracted rates. This is the most labor-intensive collection activity, but also one of the most profitable. When a payment does not match the expected reimbursement for the CPT code billed, flag it for review. Common causes include incorrect modifier application, unbundled services not contractually agreed upon, and simple processing errors. File a formal appeal or reconsideration with supporting documentation. Many payers correct underpayments when presented with the contract and the discrepancy.

If reviewing every EOB is not practical, focus on high-value claims (procedures above $500) and on payers with a pattern of underpayment. Even selective underpayment recovery can recapture $15,000 to $30,000 annually.

For write-offs: implement a review and approval process. No balance should be written off without a documented reason and supervisor approval. Set a minimum threshold below which billing staff can process write-offs independently (for example, $10) and require manager review for amounts above that threshold. Review write-off reports monthly. If total write-offs exceed 2% of collections, investigate whether recoverable revenue is being dismissed prematurely.

The metrics that measure collection effectiveness

Track these four metrics monthly to monitor whether your collections system is working, using benchmarks from MGMA practice management data.

Net collection rate. Total payments received divided by expected reimbursement (charges minus contractual adjustments). Target: 95% or higher. A rate below 93% indicates systematic collection gaps across one or more of the four categories above.

Days in AR. Total AR divided by average daily charges. Target: below 40 days. Above 45 days means revenue is converting to cash too slowly, and the aging report will show where the backlog is concentrating.

Denial resolution rate. Percentage of denied claims that are reworked and paid within 60 days of denial. Target: 85% or higher. Below 70%, denials are being abandoned rather than worked, and the practice is leaving recoverable revenue uncollected.

Patient collection rate. Patient payments received divided by total patient responsibility posted. Target: 80% or higher. Below 70%, the practice has weak patient billing processes, insufficient point-of-service collection, or both.

Collection performance benchmarks at a glance

Every percentage point of collection rate is real money

On $1.85 million in expected collections, improving your collection rate from 93% to 96% recovers $55,500 annually. That revenue requires no additional patients, no additional clinical hours, and no additional staff. It requires only the systematic processes that ensure the revenue already earned moves from the adjudicated claim to the profit and loss statement.

The medical and healthcare practices that collect 96% or above are not staffed with superhuman billers. They have systems that work every denial within 72 hours, collect patient responsibility at the visit, review EOBs against contracted rates, and control write-offs with approval processes. Those systems cost far less than the revenue they recover.

Frequently asked questions

What is a good net collection rate for a medical practice?

A net collection rate of 95% or higher is the benchmark for a well-functioning collection system. This measures total payments received as a percentage of expected reimbursement (charges minus contractual adjustments). Below 93%, the practice has systematic gaps in at least one area: unworked denials, aged patient balances, undetected insurance underpayments, or write-offs that are not reviewed. Most practices do not know their net collection rate because their accounting system records deposits rather than tracking payments against expected reimbursement by CPT code and payer.

How long does a medical practice have to rework a denied claim?

Each payer has its own timely filing limit for appeals, which typically ranges from 60 to 180 days from the date of the original claim submission. Missing this window permanently eliminates the right to collect on that claim. This is why same-day or next-day denial review is essential: the longer a denial sits unworked, the higher the risk of missing the appeal deadline. Most payers publish their appeal timelines in the provider manual. Tracking these by payer and building them into your denial management workflow prevents the compounding revenue loss that comes from missed filing windows.

What is the best way to improve patient collections?

Point-of-service collection is the single most effective intervention. Verify insurance benefits before the visit. Calculate the estimated patient responsibility based on the plan's copay, coinsurance, and remaining deductible. Collect that estimated amount at check-in or check-out before the patient leaves. Practices that implement consistent point-of-service collection reduce patient AR by 30% to 40% and eliminate most of the labor cost associated with billing, following up, and writing off patient balances after the fact. The collection probability on a patient balance at the time of service is close to 100%. At 120 days, it is below 25%.

How do I know if my practice is experiencing insurance underpayments?

Compare each explanation of benefits (EOB) payment to the expected reimbursement for the CPT code billed under the payer's contracted rate. If the payment amount is lower than the contracted rate without a documented reason, the claim has been underpaid. Many practices do not detect underpayments because payment posting is done by dollar amount rather than by comparing against contracted rates. Start by reviewing high-value claims (above $500) and any payer that consistently pays slightly below expected amounts. Even a 3% underpayment rate on $1.2 million in annual insurance payments is $36,000 in contracted revenue not received.

When should write-offs be reviewed in a medical practice?

Write-offs should be reviewed monthly at the aggregate level and individually at the time they are processed for any balance above a documented threshold. A reasonable policy allows billing staff to write off balances under $10 without supervisor approval and requires manager review above that amount. Monthly write-off reports should show total write-offs as a percentage of collections. If that percentage exceeds 2%, investigate whether the write-offs represent true bad debt, premature dismissal of collectible balances, or systematic underpayments that are being written off rather than appealed.
