Basic Medicare Information – Medical Coding

 Last week I asked an office manager for a patient’s Medicare ID number because there was no copy of the card in her medical record. The claim denied for invalid HIC (Health Insurance Claim) number. Her response was, take the patient’s social security number off the registration and add an “A” to it. I listened to her response incredulously and decided to take matters into my own hands. I called the patient.

Another time I received a denial for no Part B coverage. The office manager stated that the patient “did” have Part B coverage because her ID was 555-55-5555B. I realized at that moment that this was no coincidence. My staff deals with this lack of knowledge every day. That is when I decided to give a quick lesson in basic Medicare information. As more and more people have joined the Medicare generation, front desk and billers need to understand how the system works.

Basic Medicare Information – Medical Coding

First, there are four types of Medicare: A, B, C, and D, which cover various services. Most people receive Medicare benefits from the Federal Government:
Part A is hospital insurance coverage only and you will only see Part A listed on the patient’s Medicare card. This covers hospital, hospice, home health care and skilled nursing facilities. “Facility” is the key word here. This does not apply to a physician who provides his “physician services” in a hospital location.

Part B coverage is medical coverage. On the insurance card, you will see Part A AND Part B listed as the type of coverage the patient has. Part B coverage is paid with a monthly premium and covers physician services, durable medical equipment, preventive care and inpatient and outpatient services, lab tests, X-Rays, mental health care and some home health and ambulance services.

Part C is a health care option offered by private payers that provide Medicare benefits in the form of an HMO or PPO. Plan C is called “Medicare Advantage Plan”. Patients must be wise when choosing this form of Medicare coverage. It replaces the original Medicare and acts like an HMO-PPO. They must be certain that the physician and hospital they choose accept the Part C coverage. Hospitals contract with certain HMO-PPO plans and do not accept all Part C plans.

Part D is an outpatient prescription drug insurance and is provided by private insurance companies that have contracts with the government. Part D is never paid for by the government, like Medicare claims are. It is an option for patients due to their needs. If a patient is covered by the original Medicare program, they must choose a stand-alone Part D plan.

I have provided a list of suffixes Medicare attaches to the patient’s SSN. As you can see, an ID number ending in “A” does not mean Part A only and if the ID number ends in “B”, it does not mean Part B coverage only.
