What is medical billing and coding?

Medical billing and coding are often referenced simultaneously, but they are two distinct processes.

• Medical coding is the process of translating medical procedures and diagnoses into standardized codes for accurate billing and insurance reimbursement
• Medical billing refers to submitting claims and collecting payments for services rendered after determining the correct codes to assign to them

The medical coding process involves learning several different coding systems that serve distinct purposes.

• International Classification of Diseases (ICD) codes are used to categorize diagnoses, which indicate why a patient needs medical attention.
• Current Procedural Terminology (CPT) and ICD-10-PCS codes are used to categorize the procedures performed on the patient.
• Healthcare Common Procedure Coding System (HCPCS) Level II codes identify products, supplies, and services not found in CPT codes, primarily for Medicare and Medicaid coding.

Why medical billing and coding accuracy matters

Accurate medical billing and coding is crucial to supporting your practice’s financial health. Inaccurate coding leads to claim denials, requiring more time and effort to fix the issue and eventually receive reimbursement. Outside the insurance process, billing errors can prevent your practice from receiving accurate, sufficient payment for the services you provide, affecting revenue.

Billing and coding errors can even lead to compliance risks, exposing healthcare providers to investigations into fraud and abuse. Even unintentional mistakes can create financial and legal liabilities under the False Claims Act.

Dedicating the necessary time and attention to the medical coding process improves accuracy and, ultimately, your cash flow. If you are new to the medical billing and coding process, reviewing examples may be a good starting point.

Medical coding examples explained

Medical coding follows a systematic process for assigning appropriate codes to procedures and diagnoses after patient appointments. These examples can help you understand how the process works in real-world scenarios.

Example 1: Procedure coding breakdown

Imagine a medical coder receives a patient record for an abscess drainage procedure. This is the process the coder would follow to turn that procedure into the correct medical code:

1. Review the patient record and identify the procedure performed. In this case, it was a CT-guided drainage of a retroperitoneal peripancreatic fluid collection.
2. Review indications to justify the procedure. The coder would then review the patient’s file for symptoms, test results, or other observable signs that act as evidence to guide the coding. In this case, the coder sees that a CT scan has been performed, and the images show a mass that may represent an abscess.
3. Look for medications used. Patients/insurance companies need to be billed for medications used during procedures. The coder sees that a moderate sedative was used for this procedure.
4. Evaluate lab actions. The coder also notes that the surgeon collected aspirated purulent fluid for lab evaluation, which will also need to be coded.
5. Assign the appropriate codes. With all this information identified, the coder can assign the appropriate medical codes to each step of the procedure. This case specifically used CPT 49405-59, which represents a “Distinct Procedural Service” related to a percutaneous, image-guided catheter drainage of a fluid collection.

Example 2: Multi-code procedure scenario

Complex medical cases often involve assigning multiple codes to the same procedure. A medical coding example of this scenario could encompass assigning codes to a cholecystostomy exam. The coder would follow these steps:

1. Identify the procedure. The coder would identify that the specific procedure performed was a guided cholecystostomy drainage.
2. Review indications to justify the procedure. The coder would review the patient’s medical records to look for evidence justifying this procedure, finding that the patient was diagnosed with cholecystitis.
3. Look for medications used. The coder would see that the patient received a mild sedative during the procedure and was monitored by nurses.
4. Evaluate additional procedures. The coder would also review additional procedures performed during the cholecystostomy, which in this case included a complete ultrasound.
5. Assign the appropriate codes. The coder would determine that two separate CPT codes are needed for this procedure: 47490 (percutaneous cholecystostomy) and 49083 (image-guided abdominal paracentesis).

Medical billing examples and workflow

Medical billing involves reviewing the coded records, verifying their accuracy, and submitting insurance claims, among other tasks. This process is essential for seeking the proper reimbursement and preventing denials that waste time and money.

The following medical billing examples can help you better understand how coded data is used in the billing process and how a biller submits and tracks claims.

Example 1: Claim submission process

Medical billers are responsible for submitting claims for reimbursement and tracking their progress. These are the steps a medical biller would follow when presented with a patient record for insurance billing:

1. Verify the patient information and the codes assigned to the procedure.
2. Format the information correctly for an insurance claim, using alphanumeric character strings with no extra characters or punctuation.
3. Submit the claim to the insurance company.
4. Track the claim’s status and follow up on any issues.

Submitting accurate information is crucial, so be sure to always double-check the spelling of names, insurance ID numbers, and other data before submission.

Example 2: End-to-end revenue cycle workflow

The revenue cycle workflow for medical billing and coding begins with assigning the appropriate medical codes to the procedure performed. Then, the back-end revenue management process begins, following these steps:

1. Transfer the coded data into the practice’s billing system.
2. Apply pricing and charges to each diagnosis, procedure, and supply in the coded data.
3. Submit the claim to the insurance company or government agency responsible for reimbursement.
4. Monitor the claim status to promptly identify delays, such as rejections or denials.
5. Resolve issues that prevent the claim from being approved, such as correcting errors or resubmitting the claim.
6. Reconcile the payments and patient balances to ensure that the invoice has been fully paid.

This process can be tedious, but professional medical billers are highly familiar with it. They also know how to submit claims properly the first time to minimize denials and rejections and keep the revenue cycle moving.

Common challenges in medical billing and coding

The medical billing and coding examples above are just a few of the many ways these processes can play out across different procedures and cases. Several challenges can arise along the way, and knowing how to overcome them is an important aspect of properly overseeing revenue cycle management.

A few common challenges in medical billing and coding include:

• Coding errors and incomplete documentation that cause medical coding professionals to assign the wrong categories to procedures
• Claim denials and delays that halt the billing process or take a significant amount of time to resolve
• Ever-changing medical coding guidelines and complex payer requirements that give coders pause
• Inefficiencies in the medical coding process that negatively impact revenue

Medical billing and coding departments can take steps to reduce errors and prevent some of these challenges. Investing in ongoing staff training can help staff continually refine their skills and gain a more thorough understanding of medical terminology and coding processes. Proactive audits can catch errors before they become problems, and automated systems can streamline tasks where typos often occur.

How technology improves billing and coding efficiency

The medical coding and billing industry has evolved in recent decades to rely more heavily on technology and automation. Some practices have even begun integrating artificial intelligence into this process to streamline certain aspects and relieve burdens on overwhelmed staff members.

For example, AI can suggest certain codes or assist with much of the coding process, then transfer the data to a certified professional coder for review. Practices can use automation tools to verify insurance coverage before appointments and send automated reminders to patients with overdue bills.

Medical practices also use electronic health records, which allow real-time data access, so medical coders always see the most up-to-date information. With the right technology, medical practices can reduce manual work in medical billing and coding while ensuring that certified professionals still oversee the process.
