Claim denials have been identified by experts in healthcare RCM as one of the most critical challenges to maintaining healthy cash flows. According to research reports from the American Hospital Association, approximately 11% to 12% of medical claims are denied at initial submission.
Even more concerning is that, according to a benchmarking study conducted by the Medical Group Management Association, nearly 65% of denied claims are never resubmitted, resulting in an average revenue loss of about 3% for healthcare organizations. To safeguard your organization from financial setbacks caused by claim denials, it is essential to understand the different types of denials, become familiar with common CARCs, and implement proactive checks within your workflow. Leveraging efficient Medical Billing Services can further streamline this process, significantly reduce denial rates, and improve overall revenue performance.
Denials in medical billing implications are when healthcare insurance companies do not pay for the services rendered to the patient by a healthcare professional. These refusals may arise for several reasons, including a lack of proper documentation, wrong coding, or even the failure to get pre-authorization. Denials complicate matters in such a way that they can disrupt revenue collections and increase operational costs. For this reason, healthcare practices must find a way of handling these denials swiftly and efficiently.
Before diving into specific codes, it is critical to classify denials by their resolution path. In revenue cycle management, claims are classified as Soft Denials or Hard Denials.
Soft denials are temporary payment rejections resulting from correctable procedural or administrative errors. These claims do not require a formal appeal; instead, the billing team can quickly rectify the missing or incorrect data and resubmit the claim for processing.
Examples: Typographical errors in a patient’s name, missing insurance group numbers, or omitted modifiers.
A hard denial is an irreparable or very complicated denial of coverage related to policies, treatment decisions, or contracts. In these cases, a new application will not solve the problem, but an official appeals procedure must be pursued, and even if unsuccessful, the loss of revenue is forever.
In medical billing, denials are mostly classified into two main types – payer and provider. These classifications assist healthcare providers in recognizing the root causes and formulating measures for effective management.
When an insurance provider refuses a claim due to its policies and certain conditions that are set. Such a situation is known as payer denial.
Payer denials can come in various forms, including disallowing the claim due to lack of eligibility. This commonly occurs when the patient’s policy has been inactive during the visit. In most cases, patients may have had their insurance lapse due to failure to pay premiums. Or the care they received may have been for services not covered in their plan. Medical billing departments must check the patient’s eligibility or coverage status before booking appointments to mitigate these unwanted claim-filing challenges.
In addition to the various types of claim denial provided by various payers, one kind is an authorization denial illness. Such a denial is given if a healthcare provider renders service without seeking prior approval. Known as pre-authorization, for services that need one. Healthcare professionals may also face authorization denial if they fail to seek it for scheduled surgeries or if the authorization lapses before the service date. It is also important to know the definition of pre-authorization for each insurance plan to help avoid such incidences and unnecessary wastage of time.
It is not unusual, as it happens when the insurance companies believe that the patient’s policy does not pay for the required service. In such instances, experimental procedures and services performed by out-of-network providers often cause controversy. To avoid the backlash of coverage denials, one must appreciate the specifics of each patient’s policy and ensure that the services offered align with their respective insurance plans.
Provider denials happen because of problems with the submission process or provider mistakes.
Among the many reasons for such denials, coding errors top the list. Claims are rejected due to wrong or obsolete CPT (Current Procedural Terminology) or ICD (International Classification of Disease) codes, including but not limited to. Another reason these claims are rejected is the absence or improper use of modifiers. As mentioned initially, accurate and precise coding is fundamental in eliminating or reducing these denials. Balancing payments with the help of medical billing services prevents providers from crossing such lines.
Incomprehensive documentation is yet another notable reason for a lot of provider denials. Providers submitting claims not including appropriate supporting documentation about the services rendered will likely have their claims denied. Missing signatures, poor medical records, or even a lack of information on the services rendered may pose some challenges. To mitigate the injury, the providers must ensure adequate medical records and documentation support each submission before making the claim.
Timeliness denials occur frequently when the payer rejects claims filed after the allowed time frame. It is common for these denials to arise from late submissions or internal processing delays. Healthcare providers must ensure an efficient billing workflow and maintain submission timelines to minimize such rejections.
Based on national billing statistics, almost all denials result from just ten codes. Let’s analyze each code along with what makes it deny and an example of that denial.
This occurs when essential demographic or structural data is missing or incorrectly formatted.
Root Cause: Typos during front-desk registration or failure to verify data fields before clearing the clearinghouse.
Example: A claim is submitted with the National Provider Identifier (NPI) field left entirely blank, or the patient’s date of birth is inverted.
The patient’s insurance policy was either inactive on the date of service or the specific benefit plan does not cover the service rendered.
Root Cause: Failure to perform real-time eligibility (RTE) checks right before or on the day of the patient’s appointment.
Example: A patient loses employment and their employer-sponsored health coverage terminates on February 28th, but they receive care at your clinic on March 5th.
The service requires explicit approval from the insurance carrier before execution, but no valid authorization number was appended to the claim.
Root Cause: A mismatch between the clinical procedure performed and the specific CPT code approved in the authorization packet.
Example: An MRI is scheduled and executed based on an urgent clinical need, but the billing team fails to submit a pre-authorization request to the payer beforehand.
The diagnosis code (ICD-10) provided on the claim does not medically justify the performance of the corresponding procedure code (CPT/HCPCS).
Root Cause: Outdated, truncated, or non-specific codes that fail to meet the payer’s Local Coverage Determinations (LCD).
Example: A complex diagnostic colonoscopy is billed using only a generic, routine screening code without specifying the patient’s active high-risk indicators or symptoms.
The payer’s system flags the claim because an identical service for the same patient, provider, and date of service has already been received or processed.
Root Cause: Resubmitting an un-adjudicated claim too quickly to fix a minor issue without checking its active status, or workflow overlaps between multiple billers.
Example: A biller submits a corrected claim but forgets to include the appropriate “Corrected Claim” indicator code, leading the system to see it as a duplicate bill.
The claim was submitted outside of the contractually defined window permitted by the insurance payer.
Root Cause: Clinical documentation backlogs by providers or administrative delays in scrubbing claims.
Example: A state Medicaid program requires claims to be filed within 90 days of the date of service, but due to a credentialing delay, the provider files it on day 120.
The claim is directed towards the incorrect insurance plan due to the fact that the patient has more than one type of insurance coverage, and the primary payor has yet to be identified .
The CPT code needs a modifier to explain its clinical significance (for instance, for bilateral surgeries and the professional and technical aspects), but it is incorrect or omitted.
It is found that the service claimed is included as part of a more extensive procedure that has been claimed on the same form.
The charge made by the payer exceeds the fee schedule allowed under the insurance company’s contract.
Mitigating denials in medical billing requires a proactive approach that involves several strategies:
Given this, we recommend that providers first develop a process for patient verification. The most common reasons for denial are eligibility and authorization. Verifying the insurance coverage and eligibility before the patient’s appointment can avoid this situation. This preliminary step is time-effective and prevents hassles with future claims submissions to insurance companies.
It is important to apply intelligent software for claim scrubbing using up-to-date, payer-specific NCCI edits. The claim scrubbing software serves as an automatic gatekeeper, identifying issues such as missed modifiers (CO-4), formatting errors (CO-16), and duplicate claims (CO-18).
Frequent personnel development is key to reducing mistakes and staying current with coding changes, insurance claim policies, and submission requirements. Competently trained billing departments handle intricate claims with maximum efficiency and minimum errors. This increases the likelihood of accepting claims. Another good way to reduce denials is to purchase sophisticated billing applications capable of handling and automating tasks like eligibility verification, coding, claim submission, and processing. Such solutions minimize the potential for human mistakes and enhance the entire billing cycle.
Perpetual audits can also assist in the recognition of usual difficulties experienced in the billing cycle. As with the analysis of denials by timeliness trends, healthcare practices also use this information to resolve the problem. Periodic audits enable the billing teams to identify and rectify mistakes before filing the claims, thereby improving accuracy and decreasing claim rejection.
Ultimately, outsourcing one’s medical billing needs to a qualified medical billing company could help resolve parties with more than the qualified ability to handle a complex billing structure. Such services are aware of the processes and requirements of the various payers’ operations, the relevant codes, and the law, thus minimizing losses due to denied claims and improving the cycle for collecting revenues. These arrangements enable healthcare practices to concentrate on caring for patients without worrying about the intricacies of billing, which experts would handle.
To keep the revenue cycle healthy, any healthcare provider needs to grasp denials in medical billing. To achieve this, we can divide denial practices into payer and provider types and develop necessary corrective actions for common causes and future measures. Billing and coding, patient documentation and verification, and outsourcing to medical billing services can greatly increase revenue collection efficiency and reduce the rate of denials. Working with denials enhances billing processes and ensures that providers’ energy is directed toward providing quality services. This approach is constructive and valuable.

A rejected claim contains formatting or clerical errors caught before processing (like a mistyped ID) and never enters the system. A denied claim has been processed by the payer but determined unpayable due to coverage, clinical, or authorization rules.
An optimal denial rate should be kept below 5%. If your practice’s denial rate exceeds 10%, it indicates systemic issues in front-desk registration, authorization workflows, or coding accuracy.
It depends on the payer contract. Commercial insurers usually allow 90 to 180 days, while Medicaid or strict managed care plans can limit the appeal window to just 30 to 60 days from the denial date.
CO-45 means the charge exceeded the contract’s maximum allowed amount. Because it is a Contractual Obligation (CO), you cannot bill the patient for this difference; it must be written off.
Beyond the delayed revenue, correcting and re-routing a single denied claim costs an average of $25 to $30 in administrative labor and billing resources.
