Understanding Cardiology Billing

Cardiology billing involves managing and submitting claims for cardiology services provided by healthcare providers to ensure proper reimbursement.

Since it involves the documentation and coding of various cardiovascular diagnoses, treatments, and procedures, it requires specialized knowledge of proper coding systems, regulatory requirements, and insurance guidelines. Furthermore, as with any medical billing process, cardiology billing comprises several steps. The most important ones you should know are the following:

  • Use of appropriate medical codes
  • Following documentation requirements
  • Claim submissions
  • Denial management
  • Regulatory compliance

Cardiology billing plays a vital role in your healthcare operations because it directly affects your revenue cycle. Failing to get reimbursed for the cardiology services you’ve offered can jeopardize your income and financial stability. So, optimizing this process will lead to more efficient business operations and maximize your revenue.

Cardiology Billing Strategies for Maximizing Revenue

After elaborating on the importance of cardiology billing, here are some of the most effective strategies you can implement for optimizing the process:

  • Coding accuracy and specificity
  • Documentation practices
  • Patient insurance verification and preauthorization
  • Timely filing and claims submission
  • Denial management and appeals

1. Coding Accuracy and Specificity in Cardiology

You should always ensure coding accuracy and specificity in cardiology. Regardless of the specialty, medical billing requires standardized code sets such as the ICD-10 (International Classification of Diseases, 10th Revision) and CPT (Current Procedural Terminology).

For cardiovascular procedures, the CPT codes usually range from 92920 to 93799. Some of the most commonly used ones are the following:

  • 92950 – 92952: Electrocardioversion
  • 93450 – 93452: Coronary angiography
  • 93505: Left heart catheterization
  • 92980 – 92998: PCI (Percutaneous coronary intervention)
  • 93604 – 93650: Cardiac ablation
  • 93510: Myocardial biopsy
  • 93770 – 93771: Carotid artery stenting

As for ICD-10 codes, some common examples are the following:

  • I49.9 – Cardiac arrhythmia (unspecified)
  • I50.1 – Left ventricular failure (unspecified)
  • I50.21 – Acute systolic (congestive) heart failure
  • R00.0 – Tachycardia (unspecified)

We always recommend our clients invest in continuous medical staff training and education to ensure the proper use of codes. This way, healthcare providers and medical billing staff can stay up-to-date with the latest coding changes and regulations to ensure coding accuracy.

Furthermore, you should conduct regular internal audits to identify potential coding errors. By utilizing sufficient software and tools, you can also reduce human error risk and prevent unnecessary denials.

2. Documentation Practices for Cardiology

While many healthcare organizations overlook the importance of the documentation process, it plays a vital role in cardiology billing. Having comprehensive records of all the patient encounters, diagnoses, treatments, and procedures supports the claims you’re billing for and acts as proof of medical necessity. Thus, some of the key components in thorough documentation are the following:

  • Patient information
  • Visit notes
  • Physical exam and diagnostic test results
  • Diagnosis
  • Treatment plans
  • Consent records

To ensure proper documentation, there are several practices you can implement in your everyday operations. For example, you can use standardized templates to capture all essential information. Not only will this practice ensure completeness across your paperwork, but it also focuses on consistency.

3. Patient Insurance Verification and Preauthorization

One of the most important aspects of medical billing is verifying the patient’s insurance and preauthorization. This should be done as soon as the patient enters your facility for treatment or when they first contact you about scheduling an appointment. Gathering information about the insurance company and policy number will allow you to confirm the patient’s eligibility, coverage, and benefits.

When treating long-term patients, it’s important to have regular checkups to ensure all information is up-to-date. Remember that insurance information can change, so updating your records can prevent future inconveniences.

After you’ve gained insight into the patient’s insurance plan, you can easily identify if there are any preauthorization requirements before providing treatment. Since treating cardiology patients often requires submitting preauthorization requests, we always recommend you keep an updated list of services that fall under this category based on the different insurance providers’ guidelines.

Once you’ve identified the cardiology procedures that require preauthorization, it’s important to submit these requests as soon as possible. This will allow you the time to get the request processed and approved before the scheduled treatment. Moreover, you should always provide all the necessary information, including the patient’s diagnosis, supporting medical documentation, and the appropriate procedure codes. 

4. Timely Filing and Claims Submission

Another common issue healthcare organizations have struggled with is timely filing and claim submissions. Insurance providers such as Medicare, Medicaid, and private insurers have specified deadlines for when you can submit your reimbursement claims. Failing to meet them can result in claim denials and further inconveniences.

Thus, familiarizing yourself with the payer-specific timeframes based on which you file your claims is essential for proper cardiology billing. Since these deadlines are often subject to changes, you should always stay up-to-date with the latest payer filing timeframes and requirements.

To streamline the claim submission process, you should first optimize your workflow process. This can be done by implementing standardized procedures for documenting, coding, and claim submissions. Hence, you can use Electronic Health Records (EHR) for faster and more accurate documentation and coding while reducing the risk of human errors.

Relying on proper software can also aid in claim monitoring and tracking deadlines. We always recommend our clients utilize electronic claim submissions (EDI), which can be easily tracked from the moment of submission to the end of payment. Furthermore, many of these tools have integrated calendars that inform you of any approaching filing deadlines so you can organize and prioritize the submissions.

5. Denial Management and Appeals in Cardiology Billing

You should implement proper denial management tactics to ensure successful appeals. Even though you may have optimized your cardiology billing process, you still may experience claim denials occasionally. So, having an efficient denial management strategy set in place can prevent potential disruption of the revenue cycle and reimbursement delays.

You must first identify and analyze the claim denials to ensure the best results. For this reason, monitoring your claims daily and conducting regular audits is important to discover the most common reasons behind the denials. To further optimize the process, you can even categorize the denials based on the type, whether it’s missing information or coding errors, and identify patterns you can improve.

Moreover, the sooner you catch the denied claim, the faster you can correct its errors for a timely appeal or resubmission. During this step, gathering all necessary and missing documentation to support the claim is important. You can appoint a trained denial management team to monitor the process and handle additional tasks.
