One Common Mistake for Each of the 10 Steps of the Revenue Cycle

Understanding the complexities of cardiology billing and coding requires precision and up-to-date knowledge. This section will discuss, one common mistake that occurs at each step of the revenue cycle

1.Patient Registration

Common Mistake: Inaccurate patient information.

Ensuring accurate patient data from the start is crucial. Mistakes in patient information lead to claim rejections and delays.

2.Insurance Verification

Common Mistake: Overlooking insurance coverage limits.

Failing to verify insurance details, including coverage limits and prior authorization requirements, can result in non-payment.


Common Mistake: Skipping pre-authorization when needed.

Not obtaining pre-authorization for procedures that require it is a frequent oversight that leads to denials.

4.Charge Capture

Common Mistake: Misreporting services.

Incorrectly capturing charges for the services rendered, especially in cardiology, can significantly impact reimbursement.


Common Mistake: Using outdated or incorrect codes.

Relying on outdated CPT codes is a common pitfall. Always reference the latest “Cardiology CPT code cheat sheet” for accurate coding.

6.Claim Submission

Common Mistake: Delayed submissions.

Delaying claim submissions beyond the payer’s deadline is a simple yet common mistake that can be easily avoided.

7.Payer Adjudication

Common Mistake: Not tracking claim status.

Failing to track the status of submitted claims can lead to missed denials and unaddressed errors.

8.Payment Posting

Common Mistake: Posting payments to the wrong account.

Incorrectly applying payments can create account discrepancies and affect patient balances.

9.Denial Management

Common Mistake: Ignoring denials.

Not managing denials promptly can lead to revenue loss. Each denial should be investigated and rectified.

10.Patient Collections

Common Mistake: Ineffective communication.

Poor communication with patients regarding their balances and payment options can hinder the collection process.

CPT 93793 Billing Guidelines

The billing guidelines for CPT 93793 emphasize that this service is billable once per day and not during the same service period as other INR monitoring codes or anticoagulation management services. It is vital to ensure that documentation accurately reflects the education provided, the review of home INR test results, and any dosage adjustments made, to meet the billing requirements and justify the necessity of the service.

Understanding the Details of CPT Code 92920

CPT Code 92920 is important from the perspective of cardiology billing and coding, requiring precise application to ensure accurate reimbursement and compliance. 

92920 CPT Code Description

CPT Code 92920 pertains to the percutaneous transluminal coronary angioplasty (PTCA) procedure performed on a single coronary artery. This code encompasses the non-emergency dilation of a coronary artery using a balloon catheter to restore blood flow. It’s critical for medical coders and billers to accurately apply this code for procedures targeting a single artery to facilitate proper billing and reimbursement practices. 

Maximizing Reimbursement for CPT Code 93015

Understanding the complications of CPT Code 93015 is essential for healthcare professionals striving to ensure their billing processes are both efficient and compliant. This section emphasizes strategies to maximize reimbursement for this crucial code, forming a core part of our “Cardiology CPT code cheat sheet.”

Learning CPT 93015 for Effective Billing

CPT Code 93015 encompasses cardiovascular stress testing, which includes supervision, EKG monitoring, interpretation, and report. This test is a cornerstone in diagnosing and managing patients with cardiovascular conditions. 

Documenting Medical Necessity

Ensure that patient records demonstrate the medical necessity for performing a cardiovascular stress test. This includes detailed patient history, symptoms, and prior diagnostic test results. Precise documentation can defend against denials for lack of necessity.

Understanding Payer Policies

Familiarize yourself with different insurance payers’ policies regarding CPT 93015. Some insurers may have specific requirements for reimbursement of stress tests, including pre-authorization. Staying informed about these policies is key to reducing claim rejections.

Correct Modifier Usage

When appropriate, use modifiers to indicate specific scenarios (e.g., when only a portion of the test is conducted). Correct modifier applications can play a critical role in ensuring full reimbursement for the services provided.

Timely and Accurate Claim Submission

Errors in claim submission can lead to delays or denials. Ensure claims are submitted accurately and within the payer’s deadline. Utilize electronic health records and billing software to streamline this process and minimize errors.

Decoding the Echocardiogram: CPT Code 93306

Explore the comprehensive aspects of what CPT Code 93306 includes, focusing on the technical details of transthoracic echocardiography.

Documentation Best Practices

Following are the best documentation practices for CPT Code 93306:

Detailed Procedure Description: Ensure that the medical record thoroughly documents the use of 2D imaging, M-mode, spectral, and color flow Doppler, as required by CPT 93306. This documentation supports the medical necessity and comprehensiveness of the procedure.

Medical Necessity: Record the patient’s medical condition or symptoms that necessitate the echocardiogram. This links the procedure directly to patient care, reinforcing the claim’s validity.

Physician Interpretation: Include a detailed interpretation report from the cardiologist, highlighting findings, clinical significance, and any recommendations for further management or follow-up care. This report is a crucial component of the billing process for CPT 93306.

Common Billing Pitfalls to Avoid: Incomplete Documentation: Failing to provide complete documentation of all elements covered by CPT 93306 can lead to claim denials. Each aspect of the procedure—2D imaging, M-mode recording, and Doppler echocardiographies—must be documented.

Incorrect Coding: Be wary of miscoding, especially confusing CPT 93306 with other echocardiography codes that cover different aspects or extents of the procedure. Using the wrong code can result in denied claims or improper reimbursement.

Overlooking Modifier Use: In cases where multiple procedures are performed during the same session, appropriate use of modifiers is essential to signal to payers that separate and distinct services were provided, avoiding denials for perceived duplicate billing.

Failure to Verify Insurance Coverage: Before performing the echocardiogram, verify the patient’s insurance coverage and understand the payer’s guidelines for CPT 93306. Some insurers may require pre-authorization for this procedure.
