Running a Rural Health Clinic (RHC) requires balancing patient care with a maze of administrative responsibilities. Among the most critical is making sure your clinic’s Medicare cost reports are accurate, timely, and fully in compliance. In this guide, we cover the fundamentals of RHC requirements, common audit challenges, and offer our readers some best practices to help.
What Makes a Rural Health Clinic Unique
RHCs exist to increase access to primary care in underserved and shortage areas. To qualify, clinics must be in a designated rural area, use a team-based approach that includes nurse practitioners or physician assistants, and comply with all requirements outlined in Medicare’s RHC certification regulations noted in 42 CFR 405 and 491. The facility must meet specific physical requirements, be a permanent or mobile unit, and be properly certified to provide authorized services. Importantly, RHCs cannot operate as rehabilitation facilities or focus primarily on mental health services.
Certification begins with Form CMS-29 (an application for Medicare/Medicaid participation) and involves state survey agencies working with CMS Regional Offices to confirm eligibility. This process uses Census Bureau data for rural designation and Health Resources and Services Administration (HRSA) data for shortage area validation, ensuring the clinic is in a rural area designated for eligibility. Verification of eligibility and compliance by the state survey agency and CMS is a crucial step in the certification process. The result is a program designed so Medicare beneficiaries in rural areas can access reliable primary care, with organizations such as CMS and HRSA setting standards and overseeing RHC operations.

Compliance and Eligibility at the Front End
Every cost report audit begins with eligibility and certification checks. RHCs must have their documentation in order. This includes:
- Filing CMS provider application and enrollment form (CMS-29, CMS-855A).
- Confirming staff licensing, certification, or registration as required by state law.
- Demonstrating compliance with federal and state safety and staffing requirements.
Taking the time to verify these foundational requirements at the front end prevents costly delays and will set the stage for a smoother audit process.
Staffing and Medical Direction: Where Auditors Look Closely
One of the most scrutinized areas in RHC audits is staffing. By regulation, each clinic must employ at least one nurse practitioner (NP) or physician assistant (PA), with physicians providing medical direction and oversight under the required professional supervision for regulatory compliance. And at least one NP or PA must be an employee rather than a contractor, a detail that can cause problems if overlooked. Certified nurse midwives also play a key role in RHCs by providing primary care services and increasing healthcare access in rural areas.
Auditors routinely check:
- Whether staffing levels meet requirements.
- If physicians are actively engaged in policy development and patient supervision.
- Documentation of record reviews, supervisory notes, and policy updates.
Services, Supplies, and Scope of Practice
RHCs are required to provide a broad range of primary care services, including preventive visits, basic lab work, and emergency response. The services provided must meet federal requirements for coverage and reimbursement. Services “incident to” a physician’s care must follow state law and be provided under direct supervision.
From an audit perspective, gaps usually arise when clinics:
- Fail to document incident-to services.
- Lack written agreements for inpatient or specialty referrals, including agreements with a home health agency participating in Medicare for continuity of care.
- Overlook laboratory certification or maintenance records.
Build a checklist of services and supplies tied directly to CMS requirements. And as side note, regularly update job descriptions and maintain minutes from policy meetings. These are good ideas for RHCs to demonstrate compliance without scrambling during an audit.
Medicare Payment and Reimbursement
Reimbursement under the All-Inclusive Rate (AIR) system is one of the defining features of RHCs. Medicare pays 80% of the AIR, with patients covering 20% coinsurance. The AIR is based on reasonable costs incurred by the clinic during the reporting period. Unlike RHCs, a federally qualified health center (FQHC) is reimbursed under a different system, where the PPS rate serves as a cap on Medicare payments, and FQHCs must meet specific federal requirements for certification and funding.
However, because AIR rates are reconciled annually through cost reports, errors in reporting can cause financial problems. Also, it’s important to accurately report bad debts as part of allowable costs for Medicare reimbursement.
Auditors often target:
- Mismatches between reported allowable costs and actual expenses. The all-inclusive rate is calculated by dividing total allowable costs by the total number of visits provided to Medicare patients.
- Missing or misclassified expenses (e.g., incorrectly categorizing capital purchases as operating costs).
- Coding and documentation gaps that undermine claims.
During annual reconciliation, payment rates may be adjusted in subsequent years using the Medicare Economic Index to reflect changes in healthcare costs.
Maintaining a disciplined accounting system throughout the year is the best defense against these issues. For a deeper dive into Medicare reimbursement mechanics (and other material), CMS provides an overview here: Rural Health Clinic Center.
Preparing for Cost Report Audits
Cost reports serve two purposes: reconciling Medicare payments and providing CMS with data on clinic operations. Audits test whether those reports are accurate.
Best practices include:
- Accurate Recordkeeping: Maintain all financial and statistical data on an accrual basis, unless exempted, and ensure comprehensive financial data is kept for audit and Medicare reimbursement purposes.
- Audit Trail Documentation: Ensure invoices, payroll records, and service agreements are organized and traceable.
- Internal Mock Audits: Conduct biennial reviews of clinical records, service utilization, and policies to mirror what auditors will do.
- Technology Support: Use EHR or practice management systems that automate tracking of bad debt, indigency documentation, and coding compliance.
Verification of compliance and eligibility before audit submission is essential so that all requirements are met and to avoid issues during the audit process.
Analytics as a Compliance Tool
Beyond compliance, analytics can strengthen both audit readiness and operational performance. Tracking key metrics, such as claim denial rates, cost per visit, and staffing ratios can help identify risks early.
For example, RHCs that monitor Key Performance Indicators (KPIs) recommended by CMS often spot billing anomalies before they become audit findings. There are cloud-based tools such as Azalea Health’s KPI dashboard that can even send real-time alerts when performance metrics fall outside compliance thresholds.
Quality Improvement and Continuous Review
RHCs are required to conduct program evaluations every two years, reviewing service utilization, clinical records, and policy effectiveness. These reviews may seem like another regulatory hurdle but can also be looked at as opportunities to demonstrate a commitment to patient care and continuous improvement.
Auditors often request evidence of:
- Biennial evaluation reports.
- Documentation of corrective actions taken after reviews.
- Patient satisfaction and quality improvement initiatives.
Keeping these evaluations in an accessible format shows auditors that the clinic is compliant and forward-looking.
Revenue Cycle Management and Audit Readiness
A recurring theme in our work with healthcare providers is that revenue cycle management (RCM) and compliance go together. Adhering to CMS regulations in all aspects of revenue cycle management is essential to ensure compliance and maintain financial health for RHCs. Streamlined RCM ensures accurate billing, prompt collections, and reliable financial reporting, all of which feed directly into cost report accuracy.
By aligning revenue cycle practices with audit preparation, clinics achieve two goals at once: compliance confidence and stronger financial health. Medicare Administrative Contractors (or MACs) play a key role in establishing RHC rates and overseeing compliance with federal requirements, which is critical for proper billing and reimbursement.

Graduate Medical Education (GME) and Workforce Development
Rural health clinics can even play a pivotal role by participating in training programs that bring new physicians and healthcare professionals to underserved areas. Through the Medicare program, RHCs may receive direct GME payments to help offset the costs of training residents, with funding mechanisms supported by the prospective payment system and the physician fee schedule. These payments not only support the clinic’s operational costs but also contribute to the long-term development of a skilled workforce dedicated to rural health.
By partnering with academic institutions and other healthcare organizations, RHCs can tailor GME programs to address the health needs of their patient populations. Such collaborations help ensure that physicians and other providers are well-prepared to deliver high-quality, patient-centered care in rural settings.
Emergency Preparedness and Response
Emergency preparedness is a critical component of compliance and patient safety for rural health clinics. The Centers for Medicare & Medicaid Services (CMS) require every RHC to develop and maintain a comprehensive emergency preparedness plan. This plan must outline clear policies and procedures for responding to a wide range of emergencies, from natural disasters to public health crises, ensuring that patient care services continue with minimal disruption.
Regular staff training and emergency drills are essential to keep teams ready to respond effectively. RHCs must also establish protocols for communication with patients, staff, and local authorities during emergencies, as well as strategies for triage, treatment, and, if necessary, safe transfer of patients to other facilities. By prioritizing emergency preparedness, rural health clinics demonstrate their commitment to the health and safety of their patients, staff, and communities, while maintaining compliance with CMS and Medicaid services requirements.
Maintaining a Strong Primary Care Workforce
A strong primary care workforce is the foundation of effective, patient-centered care in rural health clinics. To attract and retain talented providers, RHCs should offer competitive salaries, comprehensive benefits, and opportunities for ongoing professional development. Creating a supportive and positive work environment is equally important for provider satisfaction and retention.
RHCs can further strengthen their workforce by offering assistance programs such as loan forgiveness, relocation support, and flexible scheduling. Collaborating with academic institutions and healthcare organizations to develop pipeline programs can help recruit new graduates and encourage them to build their careers in rural settings. By investing in their primary care teams, RHCs can make sure that patients continue to receive comprehensive, coordinated care and that the clinic remains a vital resource for the community.
Patient-Centered and Collaborative Models
Auditors increasingly look beyond finances to see whether clinics are aligning with broader healthcare priorities, such as Patient-Centered Medical Home (PCMH) recognition or participation in Accountable Care Organizations (ACOs). Hospitals and provider-based RHCs can participate in ACOs, playing a key role in care coordination and collaboration across healthcare settings.
While these programs are voluntary, they demonstrate a clinic’s commitment to quality and care coordination, which can strengthen standing in audits and payer negotiations. Resources from the National Association of Rural Health Clinics are particularly helpful for providers exploring ACO or PCMH participation.
Final Thoughts
Rural Health Clinics are an important part of America’s healthcare system. And for them to continue to run efficiently and in compliance, it’s important to remember these best practices. Again, timely submission of cost reports, consistent maintenance of financial and statistical records for HHS/GAO review, and clear staffing documentation that reflects PA/NP employment status. It also includes keeping service agreements and lab certifications up to date, conducting biennial program evaluations with documented corrective actions, and ensuring that independent RHCs maintain operational structure records to support proper billing.
When these best practices are integrated into everyday operations, clinics reduce last-minute scrambles and position themselves for smoother audits. More importantly, they shift compliance from being a reactive task to an ongoing rhythm of accuracy and transparency.
