The healthcare industry is always on the move, and nowhere is this more apparent than in revenue cycle management (RCM). Staying on top of the latest RCM trends isn’t just about being current; it’s about adapting your strategies to maintain financial stability, accelerate revenue, reduce denials, and deliver top-notch patient care. In a world where even your competitors are likely leveraging the latest advancements, understanding what’s trending in RCM is crucial for staying competitive.
One area that consistently demands attention for healthcare providers is the persistent headache of denied claims. According to a recent survey, half of providers reported an increase in denial rates over the past year, making effective denial management a critical component of a healthy revenue cycle. Denials can significantly impact your practice's financial health, costing precious time and resources to resolve. While claim rejections are caught before a claim is officially on file with the payer, denials occur after submission and can be just as problematic.
Indeed, the financial impact of denials is stark. As one expert notes:
"Denials can sink a profit margin, and given the cost of appeals, which is roughly $118 per claim, not all denials can be reworked. A practice submitting 50 claims a day at an average reimbursement rate of $200 per claim should bring in $100,000 in daily revenue. But if 10% of those claims are denied, and the practice can only appeal one, they lose $800 per day, upwards of $200,000 a year."
This highlights why proactively preventing denials is far more effective than trying to recover lost revenue after a denial occurs. In this comprehensive guide, we'll dive deep into common denial types, focusing particularly on routine service denials for Medicare patients. We’ll explore their causes, offer actionable resolution strategies, and, most importantly, provide preventative measures to keep your revenue flowing smoothly.
Introduction: Understanding Routine Service Denials
Let's begin with a common scenario: denials for routine services, especially for Medicare patients. These often come with Claim Adjustment Reason Codes (CARC) 204 or 49. CARC 204 indicates that the "service/equipment/drug is not covered under the patient's current benefit plan," while CARC 49 specifically states "non-covered services because this is a routine exam or screening procedure". These denials are frequently encountered when dealing with Medicare or other payers who follow Medicare guidelines.
Why Routine Services Are Denied by Medicare
Medicare has specific policies regarding what it considers a "routine" service, and generally, routine physical exams are never covered by Medicare. There are narrow exceptions, such as the "Welcome to Medicare Physical" or the Initial Preventive Physical Exam (IPPE). Beyond these specific guidelines, the use of certain ICD-10 and procedure codes will "trigger the edit at Medicare for these routine services," leading to a denial. Understanding these coding triggers is your first line of defense.
Resolution Strategies for Routine Service Denials
When you receive a denial for a routine service, your immediate goal is to investigate and resolve it efficiently. Here’s how:
Verify Coding Accuracy: The first step is to confirm that the correct CPT (Current Procedural Terminology) and ICD-10 (International Classification of Diseases, 10th Revision) codes were billed for the services rendered. A simple error in charge entry or coding can easily trigger an incorrect denial. If you find such an error, correct it promptly and resubmit it as a corrected claim.
Review ABN Modifiers: If your coding is accurate, the next step involves reviewing the claim for the appropriate use of Advance Beneficiary Notice (ABN) modifiers. These include GA, GZ, or GUI. ABNs are crucial for informing Medicare beneficiaries that Medicare may not cover a service, and the patient may be financially responsible.
Prevention: The Power of Advance Beneficiary Notices (ABNs)
Preventing routine service denials largely hinges on the proper use and understanding of Advance Beneficiary Notices (ABNs). This is where proactive measures can save your practice significant revenue and administrative burden.
Comprehensive Team Education: It’s vital to educate all members of your revenue cycle team about ABNs, Medicare routine services, and the proper usage of ABN modifiers. The rules can be complex, and ongoing training ensures everyone is up to speed on the nuances.
Utilize CMS Resources: The Centers for Medicare & Medicaid Services (CMS) website (CMS.gov) is an invaluable resource. It offers a wealth of information on ABNs and their proper use, especially for services deemed "exclusive or considered not medically necessary". Medicare contractors and their portals also provide excellent resources.
Ethical Billing: CO vs. PR Denials: This distinction is paramount for billing Medicare beneficiaries fairly and ethically. It is one of the most critical aspects of ABNs:
"It is very important to remember that you cannot bill Medicare patients when your denial has the CO (contractually obligated) prefix. You can only bill Medicare patients when the denial has a PR (patient responsibility) prefix, which ABNs and their modifiers are designed to trigger."
When a denial comes with a "CO" prefix, it means your practice is contractually obligated not to bill the patient for that service. However, if the denial has a "PR" prefix (patient responsibility), and an ABN was properly executed, you can bill the patient. Understanding this fundamental difference is key to compliant and ethical billing practices.
Proactive Compliance for Medicare Revenue Integrity (and other Common Denials)
Beyond routine service denials, many other common denial types can impact your practice’s financial health. A proactive approach, leveraging technology and robust processes, is essential for overall revenue integrity.
Timely Filing Denials (CARC 29)
This is one of the most frustrating denials because it often indicates a breakdown in internal processes. CARC 29 means "The time limit for filing has expired".
Causes:
Payer Guidelines: Each payer has strict timely filing guidelines for initial claim submissions, corrected claims, appeals, and reconsiderations. These limits can be based on the date of service or the date of receipt.
Contract Overrides: Sometimes, a provider's contract with a payer might specify a different timely filing limit than the payer's general billing guidelines. Always double-check your contract if a denial seems inconsistent with published guidelines.
Incorrect Submission Indicators: A corrected claim or an appeal might be processed as an initial claim if the correct indicators aren't used, leading to a timely filing denial.
Resolution Strategies:
Confirm Limits: Before accepting the denial, always confirm the payer's timely filing limit.
Patient Involvement: If the patient was involved in the delay, getting them to contact the payer can sometimes lead to an overturn. Payers often pay more attention to their members' requests.
Proof of Timely Filing: If you believe the claim was submitted on time, provide proof. This could be:
An electronic acceptance report showing the date the claim was accepted (not just submitted).
The claim number itself, if it contains a date indicating payer receipt.
A return receipt from the United States Postal Service for mailed documentation.
An electronic date and timestamp from the payer portal for appeals or reconsiderations. Timely filing denials can be notoriously difficult to reverse, even with proof. Some payers have very specific rules for addressing these denials.
Prevention:
Centralized Resource: Create an accessible resource for your entire team that lists timely filing limits for each payer and filing type (initial, appeals, etc.), including whether it's by date of service or receipt. Include retroauthorization limits.
Process based on Shortest Limits: Design processes (for charge entry, AR follow-up) based on the shortest timely filing limits you encounter (e.g., 30, 45, or 90 days). This ensures faster follow-up for high-risk claims.
Adequate Staffing: Ensure you have enough human resources available to follow up on claims and resolve denials in a timely manner. Without sufficient staff, even the best processes can fail.
Monitor Payer Trends: Pay close attention if a payer consistently and incorrectly denies claims for timely filing. This could indicate an internal issue at the payer or even unethical stalling tactics. While you wouldn't assume unethical behavior, bringing it to their attention with data is important.
Charge Exceeds Fee Schedule (CARC 45)
While technically an adjustment code, CARC 45 ("charge exceeds fee schedule, maximum allowable, or contracted, legislative fee arrangement") often functions as a denial when payers use it to indicate they won't pay on a line item, especially if the adjustment equals 100% of the charge. This is technically not how the code is supposed to be used according to its description.
Causes:
Payer Misapplication: Payers may incorrectly use CARC 45 for items they choose not to pay, even when a more accurate reason code (like 256 or 96 for exclusions) should be used.
Resolution Strategies:
Contact the Payer: Reach out to the payer to determine the accurate reason for non-payment.
Request New EOB/ERA: If necessary, ask the payer to send an Explanation of Benefits (EOB) or Electronic Remittance Advice (ERA) with the correct reason code. This is crucial for tracking denials in your system or if you need a "PR" denial to bill the patient.
Prevention:
Identify 100% Adjustments: Create processes to proactively identify CARC 45 with a 100% adjustment. This prevents significant revenue loss.
Contract Exclusions: If you consistently receive this for services that are contractual exclusions, adjust them at the time of payment posting to avoid further issues.
Multiple Physicians/Assistants (CARC 54)
CARC 54 indicates "multiple physicians/assistants are not covered in this case".
Causes:
Payer Limitations: The payer has a limitation on the number of physicians or assistants allowed for a particular procedure.
Resolution Strategies:
Identify Payment Indicator: Use a coding software or the CMS physician fee lookup tool to identify the payment indicator for assistant surgeon or co-surgeon. These indicators (0, 1, 2, 9) determine payment eligibility and required documentation.
Take Action Based on Indicator:
If permitted with documentation (indicator 1), submit supporting medical necessity documentation.
If permitted (indicator 2), add the appropriate modifier and rebill.
If absolutely not allowed (indicator 0 for co-surgeon), adjust the charges.
If denied totally and correctly, appeal.
Non-Medicare Payers: If the payer doesn't follow Medicare guidelines, contact them for their specific policies on multiple physicians and assistants. Some non-Medicare payers might cover services restricted by Medicare.
Prevention:
Coding Software Utilization: Use coding software to identify these restrictions before claim submission.
Ethical Billing: Be careful of negligent or unethical billing. If you know a payer follows Medicare guidelines and a service is restricted, it's generally recommended not to bill for it. Purposely billing for non-covered services could lead to audits.
Multiple or Concurrent Procedure Rules (CARC 59)
CARC 59, "processed based on multiple or concurrent procedure rules," is another adjustment code that, while not a true denial, signifies a payment reduction due to multiple procedure payment reduction (MPPR) edits.
Causes:
MPPR Edits: The multiple procedures billed were run through the payer's MPPR edit. Payers have different hierarchies (e.g., first procedure at 100%, second at 50%, third at 0, or 100%, 50%, 50%, 0). This is usually based on the Relative Value Units (RVUs) from highest to lowest, though some payers process based on submission order. Modifier 59 usage can affect this hierarchy.
Resolution Strategies:
Review RVU Reduction: Verify that reductions were based on RVUs. If not, reorder the procedures (highest RVU first) and resubmit as a corrected claim or reconsideration to potentially increase revenue.
Proper Modifier 59 Placement: Review for correct use of modifier 59. Billing software might be set up to flag these CO59 adjustments, allowing practices to review them, especially for high-dollar surgeries, to ensure accurate application and optimal billing order.
Prevention:
Coder/Charge Entry Education: Educate coders and charge entry staff to enter multiple procedures in order of RVU (highest to lowest). Many billing or coding software solutions can automate or recommend this.
Coding Software Edits: Create edits in your billing software or use coding software to identify the correct order of multiple procedures.
Modifier 59 Education: Ensure coders are appropriately trained on the use of modifier 59.
Medically Unlikely Edits (MUE) (CARC 151)
CARC 151 indicates "payment adjusted because the payer deems the information submitted does not support this many frequency of services". This often means the number of units billed for a service from the same provider on the same day exceeds the maximum allowed by Medically Unlikely Edits (MUE) established by CMS.
Causes:
Exceeding MUE Limits: Billed units exceed the maximum allowed by MUEs.
Bilateral Procedure Guideline Non-Compliance: Payer billing guidelines for bilateral procedures were not followed.
Resolution Strategies:
Refer to MUE Information: Consult coding software or the Medicare physician lookup tool to determine the maximum number of units allowed. This information is typically found in a spreadsheet or column indicating MUEs.
Split Services/Correct Claims: If two units were billed but only one is allowed, you can try splitting the services into two line items and resubmit, though this doesn't always guarantee payment if only one unit per day is allowed. Otherwise, reduce the billed units to the allowed amount and resubmit as a corrected claim.
Contact Payer for Incorrect Denial: If you believe the denial was incorrect, contact the payer for reprocessing.
Bilateral Procedure Guidelines: Identify and follow the payer's specific billing guidelines for bilateral procedures (e.g., using modifier 50 with one unit and double charges, or two line items). Correct the claim accordingly and resubmit.
Prevention:
Utilize Coding Software for MUE: Determine MUE limits using coding software before submission.
Bilateral Procedure Resource: Create a team resource detailing bilateral procedure billing guidelines for each payer.
