Medical Billing Discussion: Types of Service Codes (Chart)

HCPCS Types of Service and Codes (Chart)What are the different types of service codes for medical billing? Brought to you from Medical Billing Service Review, learn all about the codes so you can be reimbursed for your services without any hassles. See full chart of codes to the right (and snippets below):

Doctors began classifying diseases during a bubonic plague outbreak in 17th-century London. The data collected enabled doctors to track causes and symptoms in the hopes of preventing further deaths.

Later coding systems had similar goals. They were also invaluable tools in disease prevention. Doctors worldwide could communicate using medical codes. Countries could also use the codes to track causes of death (as opposed to listing numbers of mortality).

Today, medical codes serve the needs of medical billers. They employ various types of service codes to show how patient’s medical information can be billed properly. Indeed, a good medical biller can increase profits at their institution, and the opposite is also true.

If you are familiar with these codes, you can make sure you are being reimbursed properly.

What Do Medical Billers Do?

Medical billers collect all relevant patient information and compile it into a bill for the insurance company. This bill is called a claim, and it must have correct diagnostic, service, and revenue codes. They help ensure the insurance company pays the claim.

Medical billers may work alongside a medical coder. Or they may themselves be the coder in addition to performing billing services.

Of course, the coder is responsible for translating patients’ clinical details into code. But the biller must understand all codes in order to process patients’ claims.

Coding can be a complicated process. There are CPT codes, ICD-10 codes, and HCPCS Level I and Level II codes. In the following sections, let’s discuss the types of codes used in billing so you can understand the system better.

ICD Codes

Patients’ diagnoses are labeled according to ICD-codes. They were developed by the World Health Organization, and there is a code for every known disease.

ICD codes tell the insurance company why the patient visited the doctor and must be linked properly to the CPT (or diagnostic) code.

Let’s examine those in the next section.

CPT Codes

CPT stands for Current Procedural Terminology. These codes are published by the American Medical Association, and right now there are about 10,000 CPT codes used in the United States.

CPT codes tell the insurance company what services the patient received. These could be medical, surgical, radiological, or diagnostic.

They are submitted on claim forms along with ICD-10 codes. All this information is needed for insurance companies to remit payment either to a provider or an institution.

CPT codes give medical professionals and insurance companies a common language. This is what makes them important. It also simplifies the claims process.

Medical billers, as well as coders, need to know both ICD-10 and CPT codes intimately. Different insurance companies reimburse similar conditions differently.

One insurance company pays a certain amount for a certain code. Another insurance company will pay a different amount for the exact same code. You can see, then, how important a medical biller’s knowledge of the types of bill codes is for financial success.

HCPCS Codes

HCPCS Level II Codes chartMedicare, Medicaid, and some other third-party payers require medical billers to use HCPCS codes. Although HCPCS codes are based on CPT codes, it can be difficult for medical billers to know which type of service code to use. That fact helps explain why experienced billers are such assets to medical offices.

HCPCS was set up in 1978, and, at first, use of these new codes was optional. That changed with the passage of the Health Information and Portability Act (HIPPA) in 1996.

HIPPA standardized coding practices. It mandated that ICD codes be used for diagnosis, while CPT and HSPCS codes were for medical procedures.

Medical billers must follow HIPPA guidelines when submitting their claims. Otherwise, insurance companies will reject them.

HCPCS codes have three levels. Level I codes are the basically the same as CPT codes (even though medical billers refer to them as HCPCS Level I codes).

Level II codes will be discussed below. In general, though, they are codes not found in CPT and refer to products, supplies, and procedures not provided by physicians.

Level III HCPCS codes were developed by state agencies for local areas. They are not recognized at the national level.

HCPCS Codes Level II

HCPCS Level II codes cover medical procedures. Medical billers use them for non-physician services such as:

  • ambulance services
  • prosthetic devices
  • drugs or surgical supplies
  • non-physician services that aren’t included in Level I codes (CPT)

HCPCS codes are submitted on a claim form called the CMS-1500.It contains HCPCS as well as other service codes.

One of these other codes is the Type of Service (TOS) code. All HSPCS codes have a corresponding TOS code, just like ICD-10 codes always go with CPT.

TOS codes refer to the procedures or services the patient experienced. It is used mainly to collect data, but it sometimes affects payment.

Another type of service code is the Place of Service (POS) code. This tells the insurance company where the patient received their services. POS codes are maintained by CMS, just like all HCPCS codes are.

There are many specific guidelines for the use of HCPCS codes. They can be highly detailed, and medical billers need to be aware of any guideline changes or modifications. Significant components like the type of equipment used or the amount of medication cannot be overlooked.

The level of detail required for proper reimbursement is great. A quality medical biller will have the expertise to stay ahead of HCPCS changes and details.

Wrapping Up on the Types of Service Codes

As you can see, there are many types of bill codes that go into making a correct insurance claim. Although medical coders are responsible for the diagnosis codes, the biller needs to understand the various types of service codes and so much more.
