Managing Denials for Dermatology Claims: Proven Solutions
by BillingFreedom | Feb 06, 2025
In dermatology practices, claim denials can significantly impact revenue and financial stability. While denial rates vary across medical specialties, the general industry average falls between 5% and 10%. However, some reports indicate that nearly 50% of denied claims can be successfully appealed and reimbursed with proper management.
Coding errors, insufficient documentation, and failure to meet medical necessity requirements are common reasons for claim denials in dermatology. To minimize denials, practices should prioritize accurate coding, thorough documentation, and timely claim submission. A structured denial management process can enhance revenue cycle efficiency and reduce financial losses.
Reviewing denial trends regularly and investing in staff training can further improve billing accuracy and claims approval rates. By leveraging these strategies, dermatology practices can optimize their revenue cycle and ensure consistent financial growth.
Common Denials for Dermatology Claims and How to Address Them
Denial management is a crucial aspect of dermatology billing, as claim rejections can impact revenue and delay reimbursements. Below are some common denial codes in dermatology claims, along with explanations and solutions to address them effectively.
CO 18 – Duplicate Claim Submission
Explanation: This denial occurs when the same claim is submitted multiple times, either accidentally or due to a system issue. In dermatology, this can happen when re-billing a specific procedure on a patient’s chart.
Solution: Instead of re-submitting the entire claim, only re-bill the specific line item that needs correction. If you’re unsure how to do this, consult your billing software provider for guidance.
CO 11 – Diagnosis and Procedure Code Mismatch
Explanation: This denial happens when the CPT code billed does not align with the ICD-10 diagnosis code. In dermatology, this can occur when submitting claims for procedures such as skin biopsies, lesion excisions, or cryotherapy without the appropriate medical necessity justification.
Solution: Check the Local Coverage Determinations (LCDs) to ensure that the diagnosis codes support the procedure being performed. The LCD guidelines can be found on the CMS website or through your Medicare Administrative Contractor (MAC).
CO 97 – Procedure Not Paid Separately
Explanation: This occurs when a billed procedure is considered bundled with another service under the Correct Coding Initiative (CCI). Dermatology procedures like multiple lesion removals, biopsies, or skin grafts may require modifiers to distinguish them as separate services.
Solution: If procedures were performed at different sites or during separate sessions, use Modifier 59 (distinct procedural service) or Modifier 79 (unrelated procedure during the post-operative period) to indicate separate billing. Always verify that the modifier usage aligns with coding guidelines.
CO B9 – Service Not Covered Due to Hospice Enrollment
Explanation: When a patient is enrolled in hospice care, Medicare does not cover services related to their terminal condition. However, dermatologists may still treat patients for unrelated conditions, such as infections or cosmetic skin concerns.
Solution: If the service provided is unrelated to the terminal illness, use Modifier GW to indicate that the condition being treated is separate from the hospice-covered diagnosis.
CO 22 – Other Payer is Primary (Coordination of Benefits Issue)
Explanation: Medicare denies claims when another insurance provider is identified as the primary payer. This often occurs if the patient has employer-sponsored insurance, Medicare Advantage, or other coverage.
Solution: To avoid denials, verify insurance coverage details during patient registration. If a claim is denied but the patient insists Medicare should be primary, instruct them to contact the Coordination of Benefits Contractor (COBC) at (800) 999-1118 to update their coverage records.
CO 24 – Capitated or Managed Care Plan Coverage
Explanation: This denial means the patient is enrolled in a managed care plan (e.g., an HMO), and services must be billed to that plan rather than Medicare.
Solution: Use your Medicare carrier’s Interactive Voice Response (IVR) system to check patient eligibility and determine where the claim should be submitted. If the patient has an HMO plan, submit the claim accordingly.
CO 16 – Missing or Incomplete Information
Explanation: Claims are denied when required details are missing, such as National Provider Identifier (NPI), referring physician details, or CLIA (Clinical Laboratory Improvement Amendments) certification numbers for dermatology lab services.
Solution:
- Ensure the group NPI is in Box 33a and the rendering provider NPI is in Box 24J on the claim form.
- The referring provider’s NPI must be entered in Box 17b when billing for pathology services.
- If lab services are performed in-house, ensure the CLIA number is listed in Box 23.
CO 31 – Patient Cannot Be Identified
Explanation: This occurs when patient demographic details do not match Medicare’s records. The most common errors include misspelled names or incorrect Medicare numbers.
Solution: Ensure patient information is entered exactly as it appears on their Medicare card. Staff handling data entry should double-check for typos before submitting claims.
Top 10 Common Reasons for Denials in Dermatology and How to Prevent Them
Denial of claims is a persistent challenge in dermatology billing, leading to financial losses and administrative inefficiencies. Understanding the most common reasons for denials and implementing proactive measures can help dermatology practices reduce rejections and improve reimbursement rates. Below are the top 10 reasons claims get denied and practical solutions to address them.
Errors in Patient Information
Even minor mistakes in patient details—such as misspelled names, incorrect birthdates, or inaccurate insurance policy numbers—can cause claim rejections. Insurance providers require precise patient data to process claims correctly.
How to Avoid This Issue
- Always verify patient information during check-in and appointment scheduling.
- Train front desk staff to double-check insurance details before claim submission.
- Automated data validation tools are used to detect errors before processing claims.
Lack of Prior Authorization
Certain dermatology treatments, such as Mohs surgery or biologic medications, require pre-authorization from the insurer. Failing to obtain authorization before providing services leads to claim denials.
Prevention Strategies
- Establish a dedicated team to handle authorization requests.
- Inform patients in advance about required pre-approvals.
- An electronic tracking system is used to monitor authorization requests and expiration dates.
Services Not Covered by Insurance
Insurance plans often exclude specific dermatological procedures, particularly cosmetic treatments like laser resurfacing, Botox, or chemical peels. Submitting claims for non-covered services results in automatic denials.
Best Practices
- Verify insurance coverage before performing procedures.
- Educate patients about out-of-pocket costs for non-covered services.
- Offer alternative payment options for elective treatments.
Incorrect Medical Coding
Errors in CPT, ICD-10, or HCPCS coding can cause claim denials. Dermatology-specific issues include incorrect use of Modifier 59 for separate procedures or unbundling codes that should be reported together.
How to Prevent Coding Errors
- Provide ongoing coding education for billing staff.
- Implement dermatology-specific billing software that flags incorrect codes.
- Conduct routine audits to ensure accurate coding and compliance.
Insufficient Medical Necessity Documentation
Payers may deny claims if they believe a procedure is not medically necessary. Common dermatology-related denials involve mole removals, biopsies, and acne treatments that insurers classify as elective unless justified with proper documentation.
Prevention Strategies
- Thoroughly document patient symptoms, medical history, and treatment rationale.
- Submit supporting clinical evidence, such as pathology reports or photographs.
- Maintain clear communication with insurance companies regarding necessity criteria.
Missing Filing Deadlines
Every insurance company sets deadlines for claim submissions, and failing to submit within the allowed timeframe results in difficult-to-appeal denials.
How to Stay Compliant
- Implement automated reminders to track claim submission deadlines.
- Set internal submission deadlines well ahead of payer requirements.
- Regularly monitor outstanding claims to avoid missed deadlines.
Duplicate Claim Submissions
Submitting the same claim multiple times—intentionally or due to system errors—can trigger denials. Duplicate claims may also raise red flags for potential fraud investigations.
Ways to Prevent Duplicate Claims
- Utilize billing software that detects duplicate submissions before processing.
- Maintain a centralized tracking system to monitor submitted claims.
- Train billing staff to verify claim statuses before resubmission.
Coordination of Benefits (COB) Conflicts
When patients have multiple insurance plans, determining the correct primary and secondary payer can be complex. They will be denied if claims are submitted to the wrong insurer first.
Prevention Measures
- Confirm patient insurance details at every visit.
- Educate patients on their insurance coordination responsibilities.
- Establish a structured process to submit claims to the correct insurer in the right order.
Incorrect Place of Service (POS) Codes
Dermatology procedures are performed in different settings, such as outpatient clinics, hospitals, or ambulatory surgery centers. Using the wrong POS code can lead to denials.
How to Ensure Accuracy
- Train billing teams on proper POS code usage.
- Conduct regular audits to check for incorrect coding.
- Use billing software that validates POS codes before claim submission.
Missing or Incomplete Documentation
Claims can be rejected if the submitted documentation does not fully support the billed service. Missing clinical notes, lab reports, or treatment plans can prevent successful reimbursement.
Best Practices for Proper Documentation
- Utilize standardized templates for clinical notes.
- Perform routine audits to ensure the completeness of medical records.
- Train providers on the importance of detailed documentation for insurance claims.
