The Practice
Prairie Health Family Medicine is a well-established family practice located in suburban Kansas City, Missouri. Founded in 2009, the practice has grown steadily to include six full-time providers: three board-certified family medicine physicians, two physician assistants, and one nurse practitioner. Together, they serve a diverse patient population spanning pediatric wellness visits through geriatric chronic disease management, averaging 180 patient encounters per day across their two-location operation.
The practice operates out of a 12,000-square-foot primary clinic in Overland Park and a smaller satellite office in Lee's Summit. They employ 28 staff members including a four-person in-house billing department, six medical assistants, four front-desk coordinators, and assorted clinical and administrative support staff. Their payer mix is typical for a suburban Midwest family practice: approximately 42% commercial insurance, 28% Medicare, 18% Medicaid, 8% Medicare Advantage, and 4% self-pay. Annual gross charges at the time of engagement with CareVixis were approximately $4.2 million, with net collections hovering around $2.8 million - a figure that, as the practice would soon discover, was significantly below what it should have been.
Prairie Health had been using eClinicalWorks as their EMR and practice management system for seven years, and their in-house billing team had been handling claims processing, follow-up, and patient billing internally since the practice's founding. While the team was dedicated and hardworking, they were fighting an uphill battle against an increasingly complex payer landscape with limited tools and outdated processes.
The Challenge
When Dr. Sarah Mitchell, the practice's managing partner, first contacted CareVixis, she described a situation that had been deteriorating for over two years. "We knew something was wrong," she recalled. "Our patient volume was up 15% year over year, but our collections were essentially flat. We were seeing more patients and working harder, but we had nothing to show for it financially. It felt like running on a treadmill."
The core issue was an 18% claim denial rate - nearly five times the industry benchmark of 4% for family medicine. Their billing team of four was spending the majority of their time resubmitting denied claims rather than ensuring clean claims went out the door in the first place. Of their denied claims, only 62% were ever successfully reworked and collected, meaning that roughly 38% of denied charges - over $285,000 annually - were simply written off as lost revenue. The team had no systematic denial tracking or root-cause analysis process. Denials were worked in the order they appeared in the work queue, regardless of dollar value or denial reason, which meant high-value claims often aged past timely filing deadlines while the team chased smaller, easier-to-resolve issues.
The practice's accounts receivable situation was equally alarming. Their average days in AR had crept up to 65 days, with a staggering 31% of their total AR balance sitting in the 90+ day aging bucket. For a practice generating $4.2 million in gross charges, this meant that at any given time, more than $750,000 was tied up in aged receivables that became exponentially harder to collect with each passing week. Cash flow was unpredictable, making it difficult to plan for equipment upgrades, provider recruitment, or the facility expansion the practice desperately needed to accommodate its growing patient base.
Perhaps the most insidious problem was chronic undercoding. The practice's providers, like many family medicine physicians, were habitually downcoding their evaluation and management visits out of fear of audits. An internal analysis later revealed that 34% of visits coded as 99213 (established patient, moderate complexity) should have been coded as 99214 (established patient, moderate-high complexity) based on the documentation provided. Similarly, the practice was systematically missing opportunities to bill for chronic care management (CCM), annual wellness visits (AWV), and transitional care management (TCM) services that they were already performing but not capturing. Their billing team lacked the clinical coding expertise to identify these gaps, and the providers were too busy with patient care to review their own coding patterns. The result was an estimated $180,000 to $220,000 in annual revenue left on the table simply because services were either not coded or coded at a lower level than the documentation supported.
Patient communication was another pain point. The front desk staff spent an estimated 14 hours per week making manual reminder calls, and the no-show rate hovered around 12%. When patients did receive bills, they often had questions that the front desk couldn't answer, leading to a cycle of unreturned voicemails and unpaid balances. Patient collections were running at just 54% - meaning nearly half of all patient-responsibility balances were going uncollected.
"I had four full-time billing staff, and they were drowning. We were denying denials, writing off good money, and our providers were coding like they were afraid of their own shadow. I knew we needed to make a change, but honestly, I was terrified of switching billing companies. Every horror story I'd heard involved a transition period where revenue drops off a cliff."
- Dr. Sarah Mitchell, Managing Partner, Prairie Health Family MedicineThe CareVixis Solution
After a comprehensive revenue audit that took just 72 hours, CareVixis identified $347,000 in recoverable revenue across three major categories: $142,000 from denial prevention and recovery, $127,000 from coding optimization, and $78,000 from improved patient collections and reduced no-shows. Prairie Health enrolled in CareVixis's full-service back-office solution, which includes coding optimization and SIPLYPhone.com SMS integration for patient communication at no additional cost.
The technology deployment began with integration into Prairie Health's eClinicalWorks system through CareVixis's 151+ API endpoint framework. This allowed real-time, bidirectional data flow between the EMR and CareVixis's AWS-hosted billing platform without requiring the practice to change any of their clinical workflows. All data transmission was encrypted using AWS Key Management Service (KMS) encryption, and the integration was completed and tested within five business days - significantly faster than the 30-60 day timelines Prairie Health had been quoted by competing billing services.
The centerpiece of the solution was CareVixis's proprietary clinical coding engine. Every encounter note flows through a rigorous five-workflow pipeline. First, the Clinical Extraction workflow parses the encounter documentation to identify all billable elements - diagnoses, procedures, time-based services, and complexity factors. Second, the Diagnosis Support workflow cross-references extracted clinical findings against CareVixis's hybrid RAG (Retrieval-Augmented Generation) system, which contains the complete ICD-10-CM code set enriched with family-medicine-specific coding guidelines, LCD/NCD references, and payer-specific rules for Prairie Health's top 15 payers. Third, the CPT Support workflow maps procedures and services to the most specific, highest-appropriate CPT codes, factoring in the 2026 E/M guidelines, time-based coding rules, and add-on code requirements. Fourth, the Gap Detection workflow identifies services that were documented but not coded - the chronic care management visits, the depression screenings, the advance care planning discussions that providers routinely performed but forgot to capture. Finally, the Contradiction Detection workflow flags inconsistencies between diagnoses and procedures, ensuring medical necessity is supported before the claim ever leaves the building.
Critically, every step in this proprietary pipeline is protected by CareVixis's HIPAA-compliant PII stripping layer. Before any patient encounter data reaches the coding engine, all protected health information is stripped using HIPAA Safe Harbor methodology across 19+ pattern types - including names, dates of birth, Social Security numbers, medical record numbers, addresses, phone numbers, email addresses, device identifiers, and more. The clinical content is analyzed in a de-identified state, and PHI is never exposed to any external system. This was a decisive factor for Prairie Health, whose compliance officer had initially raised concerns about data security in the billing process.
For patient communication, CareVixis deployed SIPLYPhone.com's integrated communication platform. This included automated SMS appointment reminders sent at 72-hour, 24-hour, and 2-hour intervals before each appointment, with one-tap confirmation or rescheduling links. For patient billing, SIPLYPhone's system delivered balance notifications via text with secure payment links, allowing patients to pay their copays and outstanding balances directly from their phones. The platform also included an Intelligent Call Bot that could answer common billing questions, provide balance information, and set up payment plans without requiring a human agent - freeing up Prairie Health's front desk staff for in-person patient care. All communications were HIPAA-compliant, with encrypted messaging and compliant call recording for quality assurance.
CareVixis also implemented its automated collections pipeline with aging bucket triggers. Claims entering the 0-30 day bucket received standard follow-up. At 31-60 days, escalated automated follow-up protocols kicked in, including electronic payer status checks and automated appeal generation for denied claims. At 61-90 days, claims were flagged for senior specialist review with direct payer phone follow-up. And any claim reaching the 90+ day bucket triggered an immediate escalation to CareVixis's AR recovery team, which specialized in aged claims resolution. This tiered approach ensured that no claim ever silently aged past its collectability window.
The Implementation
Prairie Health's transition to CareVixis was completed in a structured three-phase rollout spanning 21 days. During the first week, CareVixis's integration team connected to the eClinicalWorks system, mapped all provider credentials, loaded payer contracts and fee schedules, and configured the proprietary coding rules specific to Prairie Health's payer mix and specialty focus. The practice's existing billing team continued processing claims normally during this phase, ensuring zero disruption to cash flow.
During the second week, CareVixis ran a parallel billing operation - processing every new claim through the CareVixis platform while the in-house team continued their existing workflow. This allowed side-by-side comparison of coding accuracy and claim quality. The results were eye-opening: CareVixis's proprietary coding engine identified an average of $12.40 in additional revenue per encounter through proper code-level assignment and add-on code capture. Across 180 daily encounters, that represented approximately $2,232 per day in previously missed revenue - over $580,000 annualized.
By the third week, CareVixis assumed full billing operations. Two of Prairie Health's four billing staff members were reassigned to patient-facing roles (one became a care coordinator focusing on the CCM program that CareVixis's gap detection had identified, and the other moved to the front desk to improve patient intake efficiency). The remaining two billing staff were retained in a quality assurance role, reviewing CareVixis's output and serving as the practice's internal liaison. Dr. Mitchell noted that this was the smoothest billing transition she had ever experienced: "There was no revenue dip. In fact, our collections in the transition month were actually higher than the previous month because CareVixis was already catching coding gaps on day one."
The Results
The twelve-month results following full CareVixis implementation exceeded even the initial audit projections. Here is a detailed breakdown of the before-and-after comparison across every major revenue cycle metric:
Denial Rate: Prairie Health's denial rate plummeted from 18% to 4.0% - a 78% reduction. This was driven primarily by two factors: CareVixis's pre-submission claim scrubbing, which caught coding errors, missing modifiers, and medical necessity gaps before claims were transmitted, and the proprietary coding engine, which ensured proper code-level selection and documentation support from the start. Of the 4% of claims that were still denied, 91% were successfully appealed and collected on first rework - compared to the previous 62% rework success rate. The net result was that lost revenue from denials dropped from approximately $285,000 per year to under $18,000.
Days in AR: Average days in accounts receivable dropped from 65 to 16 days - a 75% reduction. The automated aging bucket triggers ensured that every claim was actively worked according to its age, and the real-time payer status monitoring allowed CareVixis to identify and resolve claim issues within 48 hours of submission rather than waiting for EOBs to arrive weeks later. The percentage of AR in the 90+ day bucket dropped from 31% to just 2.8%, representing a shift of over $600,000 in aged receivables back into current cash flow.
Clean Claim Rate: The practice's clean claim rate (claims accepted on first submission without rejection or denial) improved from 76% to 98.2%. This single metric had a cascading positive effect on every other KPI: fewer denials meant less rework, less rework meant faster AR resolution, and faster AR resolution meant more predictable cash flow.
Coding Optimization Revenue: The proprietary coding engine identified an average uplift of $14.20 per encounter once fully calibrated to Prairie Health's documentation patterns. The breakdown was as follows: E/M level corrections accounted for $7.80 per encounter (primarily 99213-to-99214 upgrades supported by documentation), chronic care management capture added $3.10 per encounter (the practice had 620 eligible CCM patients but had been billing CCM for only 40 of them), and add-on code and modifier optimization contributed $3.30 per encounter (including prolonged service codes, care coordination codes, and screening add-ons). Over 12 months and approximately 46,800 encounters, coding optimization alone generated $127,000 in incremental revenue - money that had been earned through documented clinical work but simply never billed.
Patient Collections: SIPLYPhone's automated SMS payment reminders and secure mobile payment links transformed patient collections. The patient collection rate improved from 54% to 87% - a 61% improvement. The no-show rate dropped from 12% to 4.3%, recovering an estimated 3,400 appointment slots over 12 months. The Intelligent Call Bot handled 73% of patient billing inquiries without human intervention, freeing front desk staff to focus on in-person patient experience. Total incremental revenue from improved patient collections and reduced no-shows was $78,000 in year one.
Total Revenue Impact: Combining denial prevention and recovery ($142,000), coding optimization ($127,000), and improved patient collections ($78,000), Prairie Health realized $347,000 in incremental revenue in its first year with CareVixis. Net collections increased from $2.8 million to $3.15 million - a 12.5% increase - with no change in patient volume, provider count, or clinical workflow. After accounting for CareVixis fees, the practice's net revenue increase was approximately $261,000, representing a return on investment of over 300%.
Operational Savings: Beyond direct revenue gains, Prairie Health realized approximately $86,000 in annual operational savings. Two billing staff positions were redeployed to revenue-generating clinical roles rather than administrative rework. Front desk phone time decreased by 14 hours per week due to SIPLYPhone automation. And the providers themselves saved an estimated 12 minutes per day previously spent on coding-related questions and rework, translating to approximately 2.5 additional patient encounters per provider per week.
"The numbers speak for themselves, but what really changed is how our practice feels. We're not chasing denials anymore. We're not guessing about our cash flow. Our providers are coding confidently because they know CareVixis's proprietary algorithm is backing them up with documentation analysis, not just rubber-stamping whatever they enter. And our patients love the text reminders - our no-show rate is the lowest it's ever been. I wish we had made this switch two years ago."
- Dr. Sarah Mitchell, Managing Partner, Prairie Health Family MedicineWhy It Worked
100% US-Based Team: One of Prairie Health's previous frustrations with their initial exploration of outsourced billing was the prospect of working with offshore teams. "We tried a consultation with one of the big national billing companies," Dr. Mitchell recalled, "and when I asked who would be working my claims, they told me it would be a team in India. Nothing against offshore workers, but when you're dealing with complex family medicine coding, Medicare guidelines, and state-specific Medicaid rules, I need someone who understands the American healthcare system inside and out." CareVixis's 100% US-based team eliminated that concern entirely. Every claim specialist, every coder, every AR follow-up agent is based in the United States, ensuring cultural fluency with the healthcare system and real-time availability during business hours.
Direct Access to Decision Makers: Unlike large billing companies where practices are assigned to account managers who serve as intermediaries, CareVixis gave Prairie Health direct access to the team leads and company leadership responsible for their account. When a complex coding question arose regarding a multi-provider shared visit, Dr. Mitchell was able to get a definitive answer within two hours from a senior coding specialist - not a four-day ticket escalation through three tiers of support. This responsiveness was particularly critical during the first 90 days of the engagement when the proprietary coding models were being fine-tuned to Prairie Health's specific documentation patterns.
Technology-First Approach: CareVixis's technology stack is purpose-built around its proprietary algorithm, not a legacy billing system with generic tools bolted on as an afterthought. The five-workflow coding pipeline, the hybrid RAG knowledge base, the automated denial prediction models, and the real-time RPM coaching tools all work together as an integrated system. For Prairie Health, this meant that the technology improved over time - as the proprietary engine processed more of their encounters, it became increasingly accurate at predicting the right codes, flagging potential denials before submission, and identifying revenue opportunities specific to their practice patterns. By month six, the engine's coding suggestions matched or exceeded human coder accuracy 99.4% of the time.
SIPLYPhone Patient Communication: The integration of SIPLYPhone.com's communication platform solved a problem that no amount of billing expertise alone could address: getting patients to show up for their appointments and pay their bills. The automated SMS reminders, Intelligent Call Bot, and secure mobile payment links created a frictionless patient experience that improved both satisfaction scores and collection rates. Prairie Health's patient satisfaction scores related to billing and communication improved from 3.2 to 4.6 out of 5.0 following the SIPLYPhone deployment.
Risk-Reversal Guarantee: The factor that ultimately gave Dr. Mitchell the confidence to make the switch was CareVixis's risk-reversal guarantee. "Every billing company promises results," she said. "CareVixis was the only one willing to put their money where their mouth is. They guaranteed that if our collections didn't improve within 90 days, we could walk away with no penalty and no fees for the transition period. That told me they were confident in their technology and their team - and it turned out they had every reason to be."
