As an internal medicine practice, medical billing and coding can be a complex and challenging process. With changing regulations, payer requirements, and coding guidelines, it can be difficult to stay up-to-date with the latest best practices. In this blog post, we will explore the key guidelines for internal medicine medical billing and coding to help your practice optimize revenue and streamline your billing process.
Understand Coding Guidelines
Coding is the foundation of medical billing, and it is essential that internal medicine practices understand the coding guidelines for accurate billing. The International Classification of Diseases (ICD) and Current Procedural Terminology (CPT) codes are the most commonly used coding systems in medical billing. ICD codes are used to describe the patient’s diagnosis, while CPT codes are used to describe the services provided by the provider.
Internal medicine practices must ensure that they use the correct codes for the services provided. For example, if a patient presents with diabetes and receives an office visit, the provider must use the correct ICD and CPT codes. It is also essential to review and update the codes regularly to ensure that the practice remains compliant with the latest regulations.
Verify Patient Eligibility and Coverage
Before providing services, internal medicine practices must verify patient eligibility and coverage to avoid any billing issues. This step is crucial to ensure that the practice is not providing services to patients who are not covered by insurance or have lapsed coverage. By verifying eligibility and coverage, the practice can avoid denials and ensure timely payment for services provided.
Document Medical Necessity
Internal medicine practices must document medical necessity for all services provided. This documentation is crucial to ensure that the payer understands why the service was provided and why it was necessary. It is also essential to ensure that the documentation is accurate and complete. Providers should include all relevant information, such as the patient’s medical history, current condition, and any other relevant information to support the medical necessity of the service provided.
Use Modifiers Appropriately
Modifiers are codes used to indicate that a service or procedure was modified in some way. In internal medicine, modifiers are often used to indicate that a service was performed as part of a procedure, or to indicate that multiple services were provided during a single visit. It is essential to use modifiers appropriately, as incorrect use can result in denied claims and lost revenue.
Stay Up-to-Date with Regulations and Policies
Internal medicine practices must stay up-to-date with the latest regulations and policies related to medical billing and coding. This includes changes to coding guidelines, Medicare policies, and changes in payer requirements. It is also essential to ensure that the practice is compliant with all regulations related to medical billing, such as HIPAA and OSHA regulations.
Conduct Regular Audits
Internal medicine practices must conduct regular audits of their medical billing and coding processes to identify any issues or areas for improvement. These audits can help practices identify trends in denials, coding errors, or other issues that may be impacting their revenue. Regular audits can also help practices identify opportunities to streamline their billing process and optimize revenue.
Consider Outsourcing Medical Billing and Coding
Many internal medicine practices find it challenging to manage their medical billing and coding processes in-house. In such cases, outsourcing medical billing and coding to a professional billing company can be an excellent option. Professional billing companies have the expertise and experience to manage the billing process efficiently, allowing internal medicine practices to focus on providing high-quality patient care.
Important CPT codes used in Internal Medicine Billing:
There are many Current Procedural Terminology (CPT) codes used in internal medicine billing, but some of the most important ones include:
- Office or other outpatient visit – This includes evaluation and management services provided in the office or other outpatient setting. The code ranges from 99201 to 99215 depending on the level of service provided.
- Initial hospital care – This code is used to bill for the initial evaluation and management of a patient in a hospital setting. The code ranges from 99221 to 99223 depending on the complexity of the patient’s condition.
- Subsequent hospital care – This code is used to bill for follow-up visits with a patient in a hospital setting. The code ranges from 99231 to 99233 depending on the complexity of the patient’s condition and the level of service provided.
- Consultation – This code is used to bill for an evaluation and management service provided by a physician at the request of another physician or healthcare provider. The code ranges from 99241 to 99255 depending on the complexity of the patient’s condition and the level of service provided.
- Preventive medicine services – These codes are used to bill for preventive care services such as annual wellness visits, immunizations, and screening tests. The codes range from 99381 to 99397 depending on the age of the patient and the type of service provided.
What are the common denials in internal medicine billing and how to overcome those denials?
There are several common denials in internal medicine billing that can occur, including:
- Medical necessity denials – These denials occur when the insurance company determines that the service provided was not medically necessary for the patient’s condition. To overcome this denial, the provider can submit additional documentation to support the medical necessity of the service, such as medical records or test results.
- Duplicate service denials – These denials occur when the insurance company determines that a service was already billed and paid for. To overcome this denial, the provider can review their billing records and provide evidence that the service was not previously billed.
- Incorrect coding denials – These denials occur when the CPT or diagnosis code used is incorrect or does not match the service provided. To overcome this denial, the provider can review their coding practices and ensure that the codes used are accurate and match the service provided.
- Timely filing denials – These denials occur when the claim is not submitted within the required timeframe. To overcome this denial, the provider can ensure that claims are submitted in a timely manner, or appeal the denial with evidence that the claim was submitted within the required timeframe.
To avoid denials in internal medicine billing, it is important for providers to ensure accurate documentation, coding, and billing practices. Providers can also work with medical billing specialists or coders to review their processes and identify areas for improvement. In addition, it is important to stay up-to-date with changes in insurance policies and regulations to ensure compliance and reduce the risk of denials.
It is important to note that CPT codes can vary depending on the specific services provided and the individual patient’s needs. It is best to consult with a medical billing specialist or coder to ensure accurate billing and reimbursement.
