Every Step of Your Billing Process Managed for You

Our team manages the entire billing process for you, including claim preparation, scrubbing submission, tracking, and denial resolution. With proven workflows built for small practices, we help you improve cash flow, reduce errors, and maintain complete visibility into your revenue at every step.

What Sets Our Cardiology Billing Apart

Cardiology billing is one of the most complex areas of medical revenue cycle management, involving high-value procedures, strict medical necessity rules, modifiers, and frequent audits. We work directly inside your existing EHR and billing system, giving you full visibility into every claim from submission to payment. Our team closely follows payer policies and national guidance from organizations like the American College of Cardiology (ACC) to ensure claims are coded, documented, and billed accurately. If you’re expanding services or adding providers, our cardiology billing services align billing workflows with credentialing status to prevent revenue delays.

Precision Coding for Cardiology Procedures

We accurately code EKGs, echocardiograms, stress tests, catheterizations, and interventional procedures to reduce denials and underpayments.

Modifier & Medical Necessity Validation

Our team reviews modifiers, diagnosis linkage, and documentation to meet payer medical necessity requirements.

Real-Time Claim Tracking

You see which claims are pending, paid, or denied, along with allowed and paid amounts, in clear and simple reports.

Denial Management & Appeals

Denied cardiology claims are corrected and appealed quickly, with root-cause analysis to prevent repeat issues.

Accounts Receivable Follow-Up

Aged cardiology claims are worked consistently so high-dollar procedures don’t turn into lost revenue.

Compliance With CMS & Payer Rules

We stay aligned with CMS cardiology billing guidance and payer policies, including updates published by CMS.

Full Billing Team Support

You’re supported by a dedicated cardiology billing team, not a single biller, ensuring continuity and accountability.

Fast, Transparent Communication

Questions and issues are addressed quickly, with proactive updates so you always know the status of your revenue.

How Our Cardiology Billing Process Works

Our onboarding process is designed for speed and accuracy, typically completed within three to five business days. We configure your billing environment, validate payer connectivity, and begin submitting clean cardiology claims without disrupting your clinical operations.

We review your cardiology services, providers, locations, and payer mix to understand your exact billing needs.

Credentialing & Network Verification

Billing and rendering providers, fee schedules, and claim rules are configured accurately in your system.

EDI, ERA & Payment Posting Setup

We ensure electronic claim submission and payment posting workflows are active and reconciled properly.

Charge Review & CPT Validation

Your charge structure and CPT usage are reviewed to ensure clean claims and proper reimbursement.

Wonderful customer service and quick Credentialing!
Rx Credentialing LLC did an excellent job helping my practice join the MCOs. Their team made the process seamless and stress-free, answering all my questions promptly. I highly recommend them—their service is efficient, professional, and reasonably priced! 😁
I am a licensed psychotherapist and could not be more pleased with the efficient, professional services from RX credentialing services. No AI or bots here. Instead, RX offers real human beings who understand the needs of solo providers or group practice owners who are spread thin and have to wear many hats. Rx has hired talented individuals, like my account manager, Tyler, who will go the extra mile for you to ensure credentialing goes smoothly. We hit a hiccup on the road to becoming credentialed, but Tyler quickly intervened, advocating for my business so that the issue was resolved and I was approved for various insurance panels--some which have very high bars or administrative requirements. RX handled it all, informing me through each step of the process with clear and concise credentialing updates that put my fears to rest. Their services are kind of like therapy for therapists, because when you worry less about admin burdens, you can better focus on the client, while growing your business capacity. I would highly recommend them to any solo or group practice needing such services.

RxCredentialing has been a wonderful partner in helping with my credentialing for my new primary care practice as well as are assisting me with a few other services. They are very knowledgeable and most importantly they are not pushy in working with my needed timeline. Moreover, they are very responsive, and I am looking forward to expanding our relationship to include their other services such as medical billing. I was fortunate to find them while searching the web and so refreshing to deal with an organization that is really focused on helping me establish a medical practice the smart way and not just spend money foolishly on things I do not need until the time is right.

Tyler has been an excellent person to work with. He kept us (our clinic) informed of our status throughout the credentialling process. They did the "heavy lifting" tracking down and following up so we didn't need to. Because this company handled our credentialling process, it allowed our company to focus on our number one priority--patient care. Thanks for taking care of us!!

Trusting a third party with your sensitive information can be difficult. I encountered this challenge while seeking credentialing services for my business with various insurance providers. Although I received numerous proposals from credentialing firms, I was uncertain about the security of my personal data. A trusted colleague recommended Rx Credentialing LLC, based on her positive experience. I decided to engage their services, and I’m pleased to report that they handled my information securely. Moreover, their expertise and competitive pricing make them an excellent choice for anyone needing credentialing support.
