Building a Business Case for RCM Optimization: A Practical Guide

Most practice owners and billing managers know their revenue cycle has room to improve. Denial rates feel higher than they should be. Claims take longer to move than they used to. The AR aging report has more in the 90-plus-day bucket than anyone would like. And the billing team is stretched across too many manual tasks to keep up. 

Knowing the problem exists is not the same as being able to justify the investment to fix it. For independent practices operating on thin margins, every operational expense needs a defensible return. A proposal to invest in RCM optimization, whether through new automation tools, a platform upgrade, or a workflow redesign, needs to answer one question clearly: what is this actually worth? 

That question requires a business case. Not a vague promise of efficiency gains, but a specific, numbers-backed argument that shows what the current state is costing the practice, what improvement looks like in measurable terms, and what the realistic return on the investment would be. 

This guide walks through exactly how to build that case, step by step, for an independent practice or billing operation at any starting point. 

Here is what we are covering: 

• Why RCM optimization needs a financial argument, not just an operational one 

• How to establish your current performance baseline using the metrics that matter most 

• How to calculate what revenue leakage is actually costing your practice right now 

• The benchmarks that define what good RCM performance looks like 

• How to frame an ROI projection that decision-makers will trust 

• Where AI-powered automation creates the most defensible financial return 

Why RCM Optimization Needs a Financial Argument 

Revenue cycle improvement conversations often start with operational pain points. Claims are getting denied at higher rates. Follow-up is falling behind. Staff are overwhelmed. These are real problems, but they are not a business case on their own. 

A business case requires quantifying what those operational problems are costing. Because until the financial impact of the current state is visible, the investment required to change it lacks context. A billing team that spends 15 hours a week on manual payer follow-up is doing a lot of work. But the business case question is: what is that 15 hours worth in collected revenue versus the cost of automating it? 

The environment in 2025 makes that question more urgent than it has been in previous years. According to the McKinsey 2025 Healthcare RCM Buyer Survey, 51% of healthcare leaders now rank AI and advanced technologies as priority focus areas for their revenue cycle, up from 33% the prior year. The most prioritized functions are denial management and appeals at 57%, and documentation and coding accuracy at 56%. These are precisely the functions where revenue leakage tends to be highest and where the financial case for investment is easiest to build. 

The practices building those cases effectively are not doing so out of ambition. They are doing so because margin pressure is forcing the conversation. According to a Kaufman Hall 2025 report, median hospital operating margins remain below 3%, with 40% of hospitals reporting negative margins in the first quarter of 2025. Independent practices face the same underlying dynamic at smaller scale: rising operating costs, flat or declining reimbursements, and a revenue cycle that has to work harder to protect every dollar it touches. 

A well-built business case for RCM optimization turns that pressure into a rationale for action, with the numbers to back it up. 

Step One: Establish Your Current Performance Baseline 

A business case for RCM optimization starts with an honest picture of where the practice stands today. That picture needs to be specific enough that improvement is measurable. Five metrics, tracked consistently, give you the baseline you need. 

Days in Accounts Receivable 

Days in AR measures how long it takes the practice to collect payment after a service is rendered. The industry benchmark for high-performing practices is under 30 days. The standard target for most well-run practices is under 35 days. AR days above 50 are a signal of systemic issues in the billing or follow-up process, and AR days above 60 represent a genuine financial risk. 

To calculate: divide your total outstanding AR by your average daily charges. If your practice carries $450,000 in AR against average daily charges of $12,000, your days in AR is 37.5. That tells you where you stand relative to benchmark before any optimization begins. 

First-Pass Acceptance Rate 

First-pass acceptance rate measures the percentage of claims accepted and processed by the payer on the first submission, without rejection or denial. The industry target is 95% or above. Top-performing practices push toward 98%. The average across practices without structured billing optimization sits significantly below that, often in the 80 to 85% range. 

Every percentage point below 95% represents claims that required rework, resubmission, and additional follow-up time. At scale, that rework is a measurable cost, in both staff hours and delayed payment. 

Denial Rate 

Denial rate measures the percentage of submitted claims that are denied by payers. The benchmark for well-optimized revenue cycle operations is below 5%. The industry average, according to 2025 data, runs between 12% and 15%. Providers reporting denial rates above 10% increased from 30% in 2022 to 41% in 2025, reflecting a payer environment that is actively tightening its review criteria. 

A practice with a 14% denial rate has a measurable gap from the 5% benchmark. Closing that gap requires understanding the root causes of current denials, which the business case analysis needs to capture. 

Cost to Collect 

Cost to collect measures the total operational expense of the revenue cycle as a percentage of revenue collected. This includes billing staff salaries, software costs, clearinghouse fees, and any outsourced billing expenses. The industry benchmark ranges from 3% to 8%, varying by practice size and specialty. Inefficient RCM operations can push this figure above 10%. 

For a practice collecting $3 million annually, the difference between a 4% cost to collect and an 8% cost to collect is $120,000 per year in operational expenses. That figure is central to any ROI calculation for automation investment. 

Net Collection Rate 

Net collection rate measures the percentage of collectible revenue actually collected after contractual adjustments. A high-performing practice targets 95% or above. The average across practices falls between 90% and 94%. A net collection rate below 90% signals significant revenue leakage from a combination of uncollected patient balances, unresolved denials, and claims that aged past the point of collection. 

Step Two: Calculate What Revenue Leakage Is Actually Costing 

Once the baseline metrics are established, the next step is translating the gaps between current performance and benchmark into dollar figures. This is where the business case becomes financially concrete. 

Quantifying the Denial Rate Gap 

Take your current denial rate and calculate how many claims per month are denied. Then calculate the average value of a denied claim. Multiply the two figures to get your monthly denied claim value. From that, estimate the recovery rate on worked denials, typically 60% to 70% for a manually managed denial process, and the time cost of that rework. 

A practice submitting 400 claims per month with a 14% denial rate is generating 56 denied claims monthly. At an average claim value of $280, that is $15,680 in monthly claim value requiring manual rework. Even with a 65% recovery rate, the practice is writing off approximately $5,500 per month in unrecovered denied claims, plus the staff time to work the recoverable ones. That is $66,000 annually in denial-related revenue leakage before staff costs are factored in. 

Quantifying the AR Days Gap 

If your current days in AR is 48 and the benchmark is 30, you are carrying 18 extra days of revenue in outstanding AR at any given time. Multiply your average daily charges by 18 to calculate the value of revenue that is delayed rather than collected. For a practice with $10,000 in average daily charges, that is $180,000 in revenue that is perpetually delayed, reducing cash flow predictability and increasing the risk that older claims age into write-off territory. 

Quantifying the Staff Time Cost 

Manual RCM tasks, including payer follow-up calls, payment posting, eligibility checks, and denial resolution, consume billing staff hours that carry a real cost. Calculate the number of hours per week your billing team spends on tasks that automation could handle, multiply by hourly cost including benefits overhead, and annualize the figure. 

If two billing staff members spend a combined 25 hours per week on tasks that fall within the scope of billing automation, at a fully loaded hourly cost of $28, that is $700 per week or $36,400 per year in labor allocated to work that does not require human judgment. That figure belongs in the cost side of the business case. 

Quantifying the First-Pass Rate Gap 

The cost of a rejected or denied claim includes not just the delayed payment but the cost of resubmission. Industry estimates typically place the cost of working a denial at $25 to $30 per claim in staff time and administrative overhead. If your practice generates 50 claims per month that require rework due to first-pass failures, that is $1,250 to $1,500 in monthly rework cost, or $15,000 to $18,000 annually, beyond any revenue that goes unrecovered. 

Step Three: Define What Improvement Looks Like 

A business case requires a destination, not just a description of the current problem. Once the financial baseline is clear, the case needs to define what RCM optimization is expected to achieve, in measurable terms, within a defined timeframe. 

Setting Realistic Improvement Targets 

The most credible business cases for RCM optimization use conservative improvement assumptions grounded in documented industry data rather than vendor-supplied best-case projections. Here is what the research supports for practices implementing structured billing automation. 

• Denial rate reduction: Practices implementing AI-powered denial management and pre-submission claim validation consistently report denial rate reductions of 30% to 50% from their starting point. A practice starting at 14% denial rate targeting a 40% reduction reaches an 8.4% denial rate, still above benchmark but a quantifiable improvement with a calculable revenue impact. 

• Days in AR reduction: Automation of claim submission, status monitoring, and follow-up workflows typically produces days in AR reductions of 10 to 20 days for practices starting above benchmark. Industry data from Qualify Health places payment velocity improvement from automation at up to 30%. 

• Cost to collect reduction: Research from Qualify Health indicates that automation reduces cost to collect by up to 27%. For a practice currently at 8% cost to collect on $3 million in annual revenue, a 27% reduction represents approximately $64,800 in annual savings. 

• First-pass acceptance rate improvement: AI coding accuracy and pre-submission claim scrubbing consistently push first-pass rates from the 80 to 85% range toward 95% and above, reducing rework volume and accelerating the payment cycle. 

Building a Conservative Three-Year Projection 

A business case built on three-year projections with conservative assumptions is more persuasive than one built on best-case outcomes in year one. Year one typically reflects partial benefit as workflows transition and the team adapts. Year two and year three reflect the full operational benefit as the automation layer stabilizes and the team redirects capacity to higher-value work. 

Structure the projection with three rows: reduced revenue leakage from denial improvement, reduced staff cost from automation of manual tasks, and the investment cost of the solution including implementation, training, and ongoing subscription. Net the figures annually to produce a clear return timeline and a total three-year ROI number that gives decision-makers a concrete financial picture. 

Step Four: Identify the Highest-Return Areas First 

Not all RCM optimization investments produce the same return at the same speed. A practical business case prioritizes the areas where financial impact is largest and fastest, building momentum before tackling the longer-tail improvements. 

Denial Management and Prevention 

Denial management is consistently the highest-priority area for RCM investment because the financial impact is immediate and calculable. Every denied claim has a defined value. Every claim resolved through automation rather than manual rework has a measurable cost saving. And every claim prevented from denial through pre-submission validation produces revenue that would otherwise have been delayed or lost. 

The business case for denial management automation is the easiest to build precisely because the numbers are already sitting in the practice’s AR data. Current denial volume, average claim value, recovery rate, and staff time per worked denial are all measurable figures that convert directly into a financial argument. 

Coding Accuracy and Compliance 

Coding errors are one of the two most common triggers for claim denial and audit risk. Research shows that within any sample of 200 claims, an average of 41% are overcoded and 45% are undercoded. Overcoding creates audit exposure. Undercoding represents revenue the practice is legitimately entitled to but not collecting. 

The business case for coding accuracy improvement has two components: the denial reduction benefit from eliminating coding-related rejections, and the revenue capture benefit from correcting systematic undercoding. The second is often larger than the first and is frequently overlooked in business case analyses that focus only on denials. 

AR Follow-Up and Payer Communication 

Claims that reach the payer and go quiet generate aging AR without generating a denial that triggers a response. Manual follow-up on pending claims is a time-intensive, low-judgment task that consumes billing staff capacity while producing inconsistent results. Automating payer status checks and follow-up escalation removes this capacity drain and ensures that every claim receives attention at the right time, not when a staff member happens to get to it. 

Patient Balance Collections 

As patient cost responsibility has grown with the rise of high-deductible plans, patient balance collections have become a larger share of total practice revenue. Digital billing tools, self-service payment portals, and automated payment reminders consistently improve patient collection rates compared to paper statement and phone-based processes. The business case for this investment connects directly to patient collection rate improvement, with the revenue impact calculated against current write-off volumes on patient balances. 

What an AI-Powered Billing Platform Contributes to the ROI Calculation 

The business case for RCM optimization ultimately rests on whether the investment produces a financial return that justifies the cost. For independent practices evaluating AI-powered billing automation, the ROI argument is grounded in three specific contributions: reduction in revenue leakage, reduction in operational cost, and improvement in revenue predictability. 

Each of these contributions maps to a specific capability. Denial rate reduction requires pre-submission claim validation and AI denial management that categorizes root causes and routes claims to resolution automatically. Days in AR reduction requires automated claim submission, continuous status monitoring, and structured follow-up without manual intervention. Cost to collect reduction requires automation of the high-volume, low-judgment tasks that currently consume billing staff time. And first-pass rate improvement requires coding accuracy that derives from clinical documentation rather than manual code selection. 

Claimity’s platform addresses each of these within a single, integrated system built specifically for independent practices and billing companies. The AI coding engine reduces the coding errors that drive first-pass failures. The pre-submission claim scrubber validates each claim against payer-specific rules before it leaves the practice. AI denial management parses ERA data, categorizes denial root causes, and queues correctable claims for resubmission automatically. The AI payer call function automates follow-up on pending claims, eliminating the phone-based follow-up work that consumes staff hours without requiring judgment. And real-time AR dashboards give billing leadership the visibility they need to manage performance against the benchmarks the business case defines. 

When a practice maps these capabilities against the financial baseline analysis described in this guide, the ROI calculation becomes concrete. The denial rate gap has a dollar value. The staff hours displaced by automation have a cost. The AR days reduction has a cash flow impact. And the investment required to achieve those results has a known cost that nets against the benefit in a clear, defensible projection. 

Step Five: Frame the Case for the Decision-Maker 

A technically sound business case that is poorly presented does not move decisions. The final step is framing the analysis in a way that connects to what the decision-maker cares about most. 

For Practice Owners 

Practice owners care about cash flow, margin, and operational sustainability. The business case should lead with the current financial cost of the status quo, expressed in annual dollars: the revenue leakage from denials, the cost of carrying excess AR days, and the labor cost of manual billing processes. Then present the net financial benefit of optimization against the investment, with a clear break-even timeline. Practice owners respond to financial arguments expressed in concrete annual dollar figures and time-to-return, not efficiency percentages. 

For Billing Managers 

Billing managers care about workload capacity, denial resolution speed, and clean claim rates. The business case for them should emphasize the specific operational improvements that reduce the burden on the team: fewer denials to work manually, fewer payer calls to make, less time spent on payment posting and eligibility checks. The financial metrics matter, but the operational relief argument is often what creates internal advocacy from the billing manager who will champion the change. 

For CFOs and Financial Leaders 

Financial leaders require the full three-year model with conservative assumptions, documented data sources for improvement benchmarks, and a sensitivity analysis that shows the return under different performance scenarios. They will scrutinize the assumptions. A business case that can withstand that scrutiny because its assumptions are grounded in documented industry research rather than vendor projections will be more persuasive than one that leads with optimistic headlines. 

Address the Change Management Reality 

The McKinsey 2025 RCM survey found that the top barriers to full automation adoption, each cited by more than 40% of respondents, were financial constraints, interoperability challenges, staff training, and change management. A business case that acknowledges these barriers and addresses how the implementation plan accounts for them is more credible than one that presents only the upside. 

Include in the case: how staff transition will be managed, what the training investment looks like, how the platform integrates with existing EHR and billing infrastructure, and what the expected adoption timeline is before full financial benefit is realized. Addressing these questions proactively removes the objections before they arise. 

The Bottom Line 

RCM optimization without a financial argument is a hard sell in any practice. The margin environment is too tight, the investment too real, and the alternatives too numerous for a proposal built on operational pain alone to move decisions. 

But RCM optimization with a financial argument, one that shows the current cost of the status quo in specific dollar terms, maps that cost against documented benchmarks, and projects a conservative return on a defined investment, is a different conversation. It shifts the question from whether to invest to which investment produces the best return and how quickly. 

The framework in this guide gives any independent practice or billing company the structure to build that case. The data is available. The benchmarks are documented. The calculation methodology is straightforward. What it requires is the discipline to pull the current performance numbers together honestly and to frame the financial opportunity clearly for the people who control the decision. 

If your practice is at the point of building that case and wants to understand what AI-powered billing automation could contribute to the ROI calculation, the starting point is a clear picture of where your revenue cycle stands today against the benchmarks that define what optimized performance looks like.
