Medicare Audits: What New York Healthcare Providers Need to Know

Medicare audits are systematic reviews of claims submitted to Medicare to ensure they comply with federal government regulations. Just as the MTA regularly inspects subway tracks to maintain safety, the Centers for Medicare & Medicaid Services (CMS) conducts audits to maintain program integrity.

These audits aim to identify improper payments, detect fraud, and ensure that services billed were medically necessary—similar to how the NYPD works to maintain order in our vibrant city.

How a Healthcare Fraud Defense Lawyer Can Defend Your Rights in a Medicare Audit

At Varghese & Associates, P.C., we understand that facing a Medicare audit can be overwhelming for healthcare providers across New York City. Our healthcare fraud defense attorneys provide strategic representation to protect your practice and professional reputation.

  • Legal representation during interviews: A defense attorney ensures your rights are protected when investigators request interviews, preventing self-incrimination and maintaining professional boundaries.
  • Document review and production: We carefully examine all documentation requests, ensuring you provide only what is legally required while organizing records to present your practice in the most favorable light.
  • Challenging statistical sampling: Medicare auditors often use statistical sampling to extrapolate findings across all claims, potentially multiplying your liability—we can contest these methodologies when they're applied inappropriately.
  • Negotiating settlements: When facing potential penalties, a skilled defense lawyer can negotiate reduced fines, manageable payment plans, or even dismissal of claims based on technical or substantive defenses.
  • Appeal representation: Our attorneys navigate the complex five-level Medicare appeals process, from redetermination requests through Administrative Law Judge hearings to Federal District Court when necessary.
  • Compliance plan development: Following a Medicare audit, our compliance experts help implement robust programs abd compliance training tailored to your specific practice, reducing the likelihood of future audit scrutiny while demonstrating good faith efforts.
  • False Claims Act defense: When Medicare audits escalate to allegations under the False Claims Act, our experienced litigators provide aggressive defense against whistleblower claims and government investigations.
  • Professional license protection: Beyond financial penalties, Medicare fraud allegations threaten your professional licenses—we coordinate defense strategies that address both billing disputes and licensing board concerns.
  • Exclusion prevention: We fight to prevent the most devastating consequence of Medicare fraud allegations: exclusion from federal healthcare programs, which can effectively end a healthcare practice.
  • Audit response strategy: From the moment you receive notice of an audit, our team develops a comprehensive strategy tailored to the specific type of Medicare audit you're facing and your unique practice circumstances.
  • Due process advocacy: Medicare auditors don't always follow their own rules—we ensure due process protections are upheld throughout the investigation, challenging procedural violations that could invalidate findings.
  • Documentation defense: When Medicare auditors challenge medical necessity or proper documentation sufficiency, we work with clinical experts to articulate how your care decisions and medical documentation meet professional standards.
  • Coding interpretation disputes: Medicare coding requirements are complex and constantly changing—we effectively contest audit findings based on reasonable coding interpretations and clinical judgment.
  • Suspension of payments protection: During extended audits, Medicare may suspend payments, threatening your practice's financial viability—we can petition for continued payment while the investigation proceeds.
  • Grand jury subpoena response: If a Medicare audit escalates to criminal investigation, our criminal defense experience becomes invaluable in responding to grand jury subpoenas and protecting constitutional rights.
  • Corporate integrity negotiations: For larger healthcare organizations, we negotiate corporate integrity agreements as alternatives to more severe penalties, allowing continued operation with enhanced oversight.
  • Extrapolation challenges: We scrutinize the statistical methodologies used to extrapolate alleged overpayments from small random samples to your entire claims history, often significantly reducing financial exposure.
  • Statute of limitations defense: Medicare contractors sometimes attempt to review claims beyond the applicable lookback period—we enforce these time limitations to protect you from improper recovery actions.
  • Intent evidence challenges: The difference between a billing error and fraud hinges on intent—our defense strategies emphasize evidence of good faith compliance efforts that contradict allegations of fraudulent intent.
  • Prepayment review removal: When your practice is placed on prepayment review following an audit, we advocate for your prompt removal from this status to restore normal cash flow and reduce administrative burden.

Common Types of Medicare Audits

1. Medicare Administrative Contractor (MAC) Audits

MAC audits are the most basic type of Medicare audit, similar to a routine check at a TSA checkpoint at JFK or LaGuardia. These contractors process Medicare claims and conduct reviews to verify their accuracy.

MAC audits often focus on:

  • Coding accuracy
  • Documentation requirements
  • Medical necessity verification
  • Proper billing procedures

If you practice in Manhattan's hospital corridor or have a small practice in Staten Island, you may encounter these Medicare audits as part of routine claims processing.

2. Recovery Audit Contractor (RAC) Audits

RAC audits function much like the city's Department of Buildings inspections—thorough and comprehensive. Congress established the RAC program to identify and recover improper Medicare payments.

RAC auditors review claims on a post-payment basis and focus on:

  • Detecting improper payments
  • Identifying duplicate claims
  • Finding incorrect coding patterns
  • Reviewing medical necessity

For healthcare providers operating near the financial district or alongside the High Line, being prepared for RAC audits is particularly important as these areas have historically seen higher audit activity.

3. Comprehensive Error Rate Testing (CERT) Audits

CERT audits are like the Health Department's restaurant inspections—they assess overall compliance rather than focusing on specific violations. The CERT program measures improper payment rates in the Medicare Fee-for-Service program.

These Medicare audits:

  • Randomly select claims for review
  • Determine if claims meet Medicare requirements
  • Calculate error rates
  • Identify patterns of improper payments

Healthcare facilities near Columbia University Medical Center or in the Bronx medical complex should be particularly mindful of CERT audits as teaching facilities often face heightened scrutiny.

4. Zone Program Integrity Contractor (ZPIC) and Unified Program Integrity Contractor (UPIC) Audits

ZPIC and UPIC audits are similar to investigations conducted by the District Attorney's office—they focus on suspected fraud. These contractors identify cases of potential fraud, waste, and abuse in Medicare claims.

These audits typically involve:

  • Data analysis to identify suspicious, unusual billing practices
  • Unannounced site visits (much like a surprise health inspection at a Times Square restaurant)
  • Medical record reviews
  • Beneficiary interviews

Healthcare providers in Queens and Brooklyn have recently seen an uptick in these targeted audits.

5. Supplemental Medical Review Contractor (SMRC) Audits

SMRC audits operate like the specialized units of the NYPD—they focus on specific issues. These contractors perform medical reviews for specific Medicare issues identified by CMS.

SMRC audits often focus on:

  • High-volume services
  • High-cost services
  • Problematic billing patterns
  • Services with high error rates

Providers near the medical corridor on First Avenue or practicing in Long Island City should be particularly attentive to SMRC audits.

6. Office of Inspector General (OIG) Audits

OIG audits are the equivalent of a full investigation by federal authorities—comprehensive and far-reaching. The OIG conducts independent audits to protect the integrity of Medicare programs.

These audits can include:

  • Comprehensive compliance reviews
  • Financial audits
  • Evaluations of program effectiveness
  • Investigations of potential fraud

Healthcare organizations near federal buildings in Lower Manhattan often report heightened awareness of OIG audit activities.

7. Targeted Probe and Educate (TPE) Audits

TPE audits function like the city's business improvement initiatives—they aim to educate while ensuring compliance. MACs conduct these audits to help providers reduce claim errors through education.

The TPE process includes:

  • Analysis of claims with high error rates
  • Review of a sample of claims
  • Education on how to correct identified errors
  • Opportunity to improve before further action

Smaller practices in neighborhoods like Astoria or Park Slope have benefited from the educational component of these audits.

How Medicare Audits Typically Proceed

Just as New Yorkers know the distinct rhythm of a subway ride from Brooklyn to Manhattan, Medicare audits follow a predictable pattern:

  1. Notification: You'll receive an Additional Documentation Request (ADR) letter, much like receiving a summons to appear at the courthouse on Centre Street.
  2. Document Collection: You'll need to gather and submit requested medical documentation and billing records—similar to collecting evidence for a case that might be heard at the federal courthouse in Foley Square.
  3. Review Process: Auditors examine the submitted documentation to determine if the claims meet Medicare requirements—a process as detailed as a curator examining artwork at the Metropolitan Museum of Art.
  4. Results and Response: You'll receive notification of the results and information about your appeal rights if claims are denied—comparable to receiving a verdict at the New York State Supreme Court on Broadway.
  5. Appeals Process: If you disagree with the findings, you can appeal through a multi-level appeals process—not unlike taking a case from the trial court to the appellate division on Madison Avenue.

Preparing for Medicare Audits

Proper preparation for Medicare audits is as essential as knowing which subway line to take to avoid delays. Healthcare providers across New York City should:

  • Maintain thorough, accurate documentation that supports medical necessity—as meticulously as architects document plans for review by the Department of Buildings
  • Conduct regular internal audits—like the routine maintenance checks at Lincoln Center before a performance
  • Keep up with changing Medicare regulations—similar to how restaurateurs must stay current with health code updates
  • Develop a specific protocol for responding to Medicare audit requests—as organized as the emergency response plans at Hudson Yards
  • Consider implementing compliance programs—as comprehensive as security protocols at Yankee Stadium

Common Issues Identified in Medicare Audits

Medicare audits frequently identify specific issues that providers should address, much like how certain intersections in the city are known for traffic violations:

  • Insufficient documentation—as problematic as incomplete paperwork at the Department of Motor Vehicles on 30th Street
  • Incorrect coding—like misreading the subway map and ending up in Coney Island instead of Columbus Circle
  • Lack of medical necessity—as inappropriate as wearing winter clothes during a summer day in Washington Square Park
  • Upcoding services—similar to a taxi charging Manhattan rates in the outer boroughs
  • Duplicate billing processes—as redundant as taking both the express and local trains to the same destination

Responding to Medicare Audit Findings

When responding to Medicare audit findings, healthcare providers should approach the situation as strategically as planning a route through midtown during rush hour:

  • Review the findings thoroughly—as carefully as examining the fine print on a lease for a SoHo apartment
  • Address each concern specifically—as precisely as navigating the narrow streets of the Financial District
  • Submit additional documentation if necessary—as promptly as catching the Staten Island Ferry before departure
  • Consider seeking legal assistance—as wisely as consulting with an architect before renovating a historic brownstone in Brooklyn Heights

Penalties for Medicare Fraud in NYC

At Varghese & Associates, P.C., we understand that healthcare providers in New York City must recognize the severe consequences of Medicare fraud allegations. Federal and state authorities aggressively pursue suspected healthcare fraud cases with penalties that can devastate practices and careers.

  • Civil monetary penalties: The government can impose fines of up to $21,563 per false claim, plus three times the amount wrongfully claimed (treble damages) under the False Claims Act.
  • Criminal fines: Convicted healthcare providers face substantial criminal fines determined by the court based on the scope and severity of the fraudulent activity.
  • Imprisonment: Medicare fraud convictions can result in federal prison sentences ranging from 5 to 10 years per offense, with healthcare providers in NYC facing particularly stringent prosecution from the Eastern and Southern Districts.
  • Exclusion from federal programs: OIG mandatory exclusion from Medicare, Medicaid, and other federal healthcare programs lasts a minimum of five years, effectively ending many providers' ability to practice.
  • Loss of professional licenses: The New York State Office of Professional Medical Conduct and other licensing boards typically initiate proceedings to suspend or revoke licenses following Medicare fraud convictions.
  • Recoupment actions: Beyond penalties, Medicare will demand repayment of all improperly received funds, often using statistical sampling to extrapolate across a provider's entire claim history.
  • Corporate integrity agreements: To avoid exclusion, providers may be required to enter costly five-year agreements requiring independent review organizations, compliance officers, and extensive reporting requirements.
  • State-level sanctions: New York maintains its own False Claims Act with parallel liability, allowing the state to pursue additional penalties for Medicaid-related fraud.
  • Whistleblower rewards: The qui tam provisions of the False Claims Act incentivize whistleblowers with rewards of 15-30% of recovered funds, increasing enforcement risk for NYC healthcare providers.
  • Asset forfeiture: Federal prosecutors may pursue forfeiture of property and financial assets derived from fraudulent claims, including practice buildings and personal property.
  • Pre-payment review: Providers under investigation often face pre-payment review of all Medicare claims, dramatically slowing reimbursement and creating cash flow challenges.
  • Reputation damage: Beyond legal penalties, Medicare fraud allegations generate negative publicity through the DOJ's aggressive press releases, damaging professional standing in New York's competitive healthcare market.
  • Civil liability to patients: Medicare fraud schemes that affect patient care can trigger private civil lawsuits from affected individuals, creating additional liability exposure.
  • Federal program suspension: During investigations, CMS may suspend all Medicare payments, immediately threatening practice viability even before any determination of wrongdoing.
  • Corporate criminal liability: In group practices and healthcare organizations, the actions of individual providers can create criminal liability for the entire entity under federal law.
  • Administrative sanctions: The Medicare Administrative Contractor can impose payment suspensions, claim denials, and enhanced scrutiny that impact daily operations.
  • Travel restrictions: Providers under indictment for Medicare fraud often face travel restrictions and passport surrender requirements, limiting personal and professional mobility.
  • Lifetime consequences: Federal healthcare fraud convictions create permanent records that impact future employment, credentialing, insurance contracting, and professional opportunities.
  • Enhanced penalties for aggravating factors: Fraud schemes involving patient harm, vulnerable populations, or large dollar amounts trigger sentencing enhancements under federal guidelines.
  • Joint and several liability: In multi-defendant cases, each participant can be held responsible for the entire amount of fraud, creating disproportionate financial exposure for minor participants.

The Role of Legal Counsel in Medicare Audits

Having skilled legal representation during Medicare audits is as valuable as having a knowledgeable guide when exploring the hidden gems of New York City. Varghese & Associates, P.C. provides support throughout the audit process, including:

  • Reviewing documentation before submission—as thoroughly as inspecting a potential residence before signing a lease
  • Preparing responses to audit findings—as carefully as crafting a winning proposal for a city contract
  • Representing providers in appeals—as effectively as presenting a case before a judge at the federal courthouse on Pearl Street
  • Developing compliance programs to prevent future issues—as strategically as planning development in a changing neighborhood like Hudson Yards

Medicare Audit FAQs

How long does a typical Medicare audit process take? Most Medicare audits take between 3-6 months to complete, though complex investigations involving multiple claims or alleged fraud patterns can extend to 12-18 months, especially when appeals are pursued through multiple levels.

Will my patients be contacted during a Medicare audit? Medicare auditors may contact your patients to verify services were provided as billed. This typically occurs during ZPIC/UPIC audits or investigations where fraud is suspected, and beneficiary interviews are used to corroborate documentation findings.

Can I continue billing Medicare during an audit? In most routine audits, providers can continue billing Medicare normally. However, in cases of suspected fraud, CMS may implement payment suspension or place you on prepayment review, significantly affecting cash flow while the investigation proceeds.

How far back can Medicare auditors review my claims? Medicare contractors typically can review claims submitted within the past 6 years, though most routine Medicare audits focus on the previous 1-3 years of billing history. The lookback period may be extended in cases of suspected fraud.

What happens if I disagree with the Medicare audit findings? You have the right to appeal Medicare audit determinations through a five-level appeals process, beginning with redetermination by the Medicare contractor and potentially culminating in judicial review by a federal court.

Should I respond to an audit without legal representation? While minor documentation requests may be handled internally, significant audit inquiries, especially those from ZPIC/UPIC contractors or the OIG, warrant legal representation to protect your interests and avoid unintentional self-incrimination.

Are there differences between private insurance audits and Medicare audits? Medicare audits involve federal regulations and potential False Claims Act liability with treble damages, while private payer audits are governed by contract terms and typically involve simpler recoupment without the risk of program exclusion or criminal penalties.

How are overpayment amounts calculated in Medicare audits? Medicare contractors often review a small sample of claims and use statistical extrapolation to calculate the total overpayment amount across all similar claims in the review period, potentially multiplying your liability exponentially.

What documentation should I maintain to prevent Medicare audit issues? Comprehensive documentation should include detailed progress notes, specific medical necessity justifications, accurate time records for timed services, proper physician orders, and evidence of qualification for each service billed to Medicare.

Can I negotiate a settlement for Medicare audit findings? In many cases, providers can negotiate settlements for audit findings, potentially reducing financial liability or establishing extended repayment plans, particularly when there are legitimate disputes about medical necessity or documentation interpretation.

How do I know which type of Medicare audit I'm facing? The request letter will identify the contractor (MAC, RAC, ZPIC/UPIC, CERT, OIG) conducting the audit. The letter's tone, scope of document requests, and specific demands provide important clues about the audit's nature and potential severity.

If I discover billing errors, should I report them to Medicare? Self-disclosure of billing errors through Medicare's Self-Referral Disclosure Protocol or OIG's Self-Disclosure Protocol may mitigate penalties and demonstrate good faith, but should only be undertaken with legal guidance to ensure proper presentation of issues.

What role do Electronic Health Records play in Medicare audits? EHR systems create unique compliance challenges, as auditors scrutinize auto-populated fields, cloned notes, and template usage. Providers must ensure EHR documentation reflects individualized patient encounters rather than standardized content.

Does having a compliance program help during a Medicare audit? An effective compliance program can significantly reduce liability by demonstrating good faith efforts to prevent fraud and may be considered a mitigating factor if violations are found, potentially reducing penalties or influencing settlement terms.

How does Medicare determine which providers to audit? Medicare uses sophisticated data analytics to identify statistical outliers in billing patterns, utilization rates, and coding distributions. High-volume billing, sudden changes in billing patterns, and anonymous complaints also frequently trigger audits.

What should I do if auditors arrive at my practice unannounced? If auditors arrive unannounced, verify their credentials, cooperate professionally but limit access to only what is legally required, take detailed notes of their requests and actions, and contact healthcare counsel immediately before providing statements.

Can one Medicare audit finding trigger additional investigations? Yes, adverse findings in routine Medicare audits often trigger more comprehensive reviews or referrals to other enforcement agencies, as contractors are incentivized to identify potential fraud patterns that warrant expanded investigation.

How do Medicare audits affect group practices versus solo practitioners? Group practices may face additional scrutiny regarding supervision requirements, incident-to billing, and shared liability for individual provider actions, while solo practitioners typically face more significant financial vulnerability if billing is suspended.

What if patient records requested in a Medicare audit are incomplete or missing? Missing or incomplete records generally result in automatic claim denials. The best approach is to provide any supporting documentation that may substantiate the service, along with an explanation addressing the specific documentation limitations.

Are telemedicine services subject to different Medicare audit standards? Telemedicine services face heightened scrutiny regarding technology platforms used, patient location documentation, provider licensure across state lines, and satisfaction of specific Medicare requirements for virtual encounters that differ from in-person standards.
