Introduction to Medical Billing

 What is Medical Billing?

Medical billing is a critical process that facilitates healthcare providers to receive payment for the services they offer to patients. It involves a series of tasks such as verifying patients' insurance eligibility and benefits, coding medical procedures and diagnoses using standardized codes, submitting claims to insurance companies, and handling billing and payment collections.

The ultimate goal of medical billing is to ensure that healthcare providers are reimbursed for the medical services they provide to patients. It plays a crucial role in the healthcare industry, as it helps to streamline the payment process, minimize errors and discrepancies, and ensure compliance with the regulatory framework governing medical billing and reimbursement.

Effective medical billing necessitates proficiency in medical coding, familiarity with insurance policies, and a deep understanding of the legal and regulatory landscape governing medical billing. By ensuring efficient medical billing practices, healthcare providers can focus on delivering high-quality care to their patients.

Types of Medical Billing Services

There are two types of billing services.

    1. In House Billing

    2. Outsource Billing

Health care providers/ Physician

A healthcare professional refers to an individual who provides medical services to patients and is eligible for reimbursement from insurance providers or government programs such as Medicare or Medicaid.

This can include a wide range of professionals such as physicians, nurses, physical therapists, occupational therapists, speech therapists, psychologists, social workers, and more.

Medical billing involves the process of submitting claims to insurance providers or government programs for reimbursement of healthcare services provided by these professionals. It is important for healthcare professionals to accurately document and code their services in order for the claims to be properly processed and reimbursed.

Medical billing professionals, such as medical coders and billers, play an important role in ensuring that healthcare providers are properly reimbursed for the services they provide and that patients are not billed incorrectly or overcharged.

Referring and Attending Physician

The referring physician and attending physician are two important roles that are involved in a patient's care.

The referring physician is the medical professional who sends the patient to a specialist or another healthcare provider for further treatment or evaluation. For example, a patient's primary care physician may refer them to a cardiologist for a cardiac evaluation.

The attending physician is the medical professional who is responsible for the overall care and management of the patient during a hospitalization or other medical procedure. The attending physician is often the specialist or healthcare provider who is providing the specific treatment that the patient needs.

In medical billing, the referring physician and attending physician are both important for insurance purposes. The referring physician must accurately document the reason for the referral and provide the necessary information for the specialist or healthcare provider to properly bill for their services. The attending physician must also document their services accurately and provide the necessary information for the hospital or medical facility to bill for their services.

Properly identifying and documenting the referring physician and attending physician is critical for accurate medical billing and ensuring that the patient's insurance coverage is applied correctly.

Note: The referring physician is must when the patient has Medicare Insurance.

Demographic Form

A patient demographic form is a document used by healthcare providers to collect basic personal and medical information about their patients. It typically includes fields for the     

• Patient's name
• Date of birth
• Gender
• Address
• Phone number
• Email address
• Emergency contact information
• Insurance details.

Collecting this information is important for several reasons. Firstly, it helps healthcare providers identify and communicate with their patients, which is essential for providing appropriate medical care. Secondly, it allows providers to verify a patient's identity and insurance coverage, which helps to ensure that services are properly billed and paid for. Lastly, demographic information can be used for research and analysis purposes, which can help improve healthcare services and outcomes.

Patients may be asked to fill out a demographic form at the time of their first appointment or when updating their information. It is important for patients to provide accurate and up-to-date information, as this helps to ensure that they receive appropriate medical care and that their insurance claims are processed efficiently. Patients should also be aware that their personal information is protected by laws such as HIPAA, which limits the use and disclosure of their health information.

Once we have collected the information from the patient, now the next step is to file a claim to the insurance carrier.

What is a Claim?

A healthcare provider or facility submits a statement or list of services (ICD & CPT) and their associated costs to insurance in order to get payment for medical services provided to a patient. This document is known as a claim, and there are two types of claims:

• Professional Claims
• Institutional Claims

Professional Claims

A professional claim is used by individual healthcare providers, such as doctors, nurses, or therapists, who provide medical services in a non-institutional setting, such as an office or clinic. These claims typically include the provider's National Provider Identifier (NPI) number, the patient's demographic information, the diagnosis and treatment codes (ICD & CPT), and the associated costs for each service provided. Professional charges are billed on a CMS-1500 form.

Institutional Claims

An institutional claim, on the other hand, is used by healthcare facilities, such as hospitals or nursing homes, to submit claims for services provided to patients in an institutional setting. These claims typically include information about the patient's length of stay, the services provided, and the associated costs. Institutional charges are billed on a UB-04 or CMS-1450.

Both types of claims are subject to review by insurance companies to ensure that the services provided are medically necessary and that the costs are reasonable and customary. Once the claim is processed and approved, the insurance company will provide payment to the healthcare provider or facility.

It is important for healthcare providers and facilities to submit accurate and complete claims in order to receive timely payment for their services. Patients should also review their insurance statements to ensure that the services listed are accurate and that they are not being billed for services they did not receive.

Once the claim is submitted to the insurance it goes through the clearing house. 

What Is Clearing House?

A clearinghouse is a crucial intermediary between billing companies and insurance companies in the healthcare industry. It acts as a bridge, ensuring that claims are accurately submitted to insurance companies after being filtered for errors and completeness.

Clearinghouses receive claims from billing companies and scrub them for errors such as incorrect patient information or missing diagnosis and procedure codes. The clearinghouse then transmits the error-free claims to the appropriate insurance company, which speeds up the payment process and reduces the likelihood of claim denials or rejections. The clearinghouse also updates the claim's status as it is being processed, providing the billing company with regular updates about the claim's status.

Patient Responsibilities:

When medical services are provided, the healthcare provider or facility submits a claim to the patient's insurance company. The insurance company then applies any deductibles, copays, or coinsurance as outlined in the policy, and determines the amount that the patient is responsible for paying. This amount is referred to as the patient's responsibility and is typically billed to the patient by the healthcare provider or facility.

Copay:

A copay is a fixed amount that a patient pays out-of-pocket at the time of receiving medical services, such as a doctor's visit or a prescription medication. The amount of the copay is predetermined by the insurance plan, and the policyholder is responsible for paying it regardless of the total cost of the service.

Coinsurance:

Coinsurance is the portion of medical expenses that the policyholder is responsible for paying after meeting their deductible. It is expressed as a percentage of the total cost of the service, and the insurance company pays the remaining percentage. For example, if the coinsurance is 20%, the policyholder pays 20% of the total cost, and the insurance company pays the remaining 80%.

Deductible:

A deductible is the amount that the policyholder must pay out-of-pocket before their insurance coverage begins. The deductible is a fixed amount determined by the insurance plan, and it varies depending on the plan's level of coverage. For example, if the deductible is $1,000, the policyholder must pay the first $1,000 of medical expenses before their insurance coverage begins.

 

What is Premium?

Premium:

A premium is the amount of money that the policyholder pays to their insurance company to maintain their coverage. Premiums are typically paid monthly, and the amount is determined by the insurance plan's level of coverage, the policyholder's age and health status, and other factors.

EOB and ERA

EOB is abbreviated as an explanation of benefit, and it is in paper format.

ERA is abbreviated as electronic remittance advice, and it is in electronic format.
