Medical Billing for Medicaid

Medical billing for Medicaid is more complicated than medical billing for Medicare simply because Medicaid programs differ from state to state. Some citizens eligible for care in one state may not be eligible for care in another state, or they may receive a more or less benefits depending on the state in which they receive care. Billing codes, claim submission protocols, reimbursement rates, and other billing information will vary by state.

You will start the medical billing process for Medicaid by filling out a state claim form for the services and procedures covered. Most state Medicaid claim forms will be divided into main two parts: information regarding the patient and/or the insured person and information regarding the healthcare provider. As you complete the Medicaid form you will input codes from the following code sets:

• International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) Codes: ICD-9-CM is the system by which official codes are assigned to medical diagnoses and procedures relating to hospital use in the U.S. The ICD-9-CM lists the official disease codes for relevant medical conditions and procedures. ICD-9-CM codes are a series of alphanumeric digits followed by a decimal point followed by one or two numeric digits.
• Place of Service Codes: Place of service codes specify where the patient received their medical care or supplies. Place of service codes are ascribed to medical facilities such as inpatient hospitals, nursing facilities, and hospices. Place of service codes are typically two digits long.
• Healthcare Common Procedure Coding System (HCPCS) Level II Codes: HCPCS Level II codes are used to identify and categorize supplies, services, and products not included in CPT codes. HCPCS Level II codes may include ambulance services and prosthetics. HCPCS Level II codes have a single letter followed by four numeric digits.
• Current Procedural Terminology (CPT) Codes: CPT codes (also known as Level I HCPCS codes) are a subset of the HCPCS and they are used for identifying and categorizing medical procedures and services. CPT codes are created and revised as necessary by an official editorial board in conjunction with the American Medical Association. CPT does are five numeric digits long.

The Difference Between Medicaid and Medicare

Medicaid and Medicare are often mentioned in the same breath, but the two programs perform completely separate functions in the American healthcare system.

Medicare

Medicare is a federal healthcare program created in 1965 with the passage of the Social Security Amendments to ensure that citizens 65 and older as well as younger persons with certain disabilities have access to quality healthcare. Medicare is administered by the Centers for Medicare and Medicaid Services (CMS). CMS manages Medicare programs by selecting official Medicare administrative contractors (MACs) to process the Medicare claims associated with various parts of Medicare. Medicare as a healthcare plan is divided into different parts, each of which cover a specific healthcare service:

• Part A (Medically necessary services): Part A of Medicare covers basic healthcare necessary to treat a pressing medical condition. Covered services may include hospital care, skilled nursing care, nursing home care, hospice care, and other support deemed essential to treating an illness or a condition.
• Part B (Preventive Care): Services covered in Part B include services or supplies needed to treat or prevent a medical condition. Part B of Medicare also covers some preventive care services such as inpatient/outpatient mental health, clinical research, and ambulance services.
• Part C (Medicare Advantage Plan): Part C of Medicare covers all healthcare services through a provider organization such as a hospital or a private practice. Patients must be enrolled in Medicare Parts A and B to qualify for Part C.
• Part D (Prescription Drugs): Part D was created in 2003 with the passage of the Medicare Prescription Drug, Improvement, and Modernization Act. It covers many prescription drug costs and is paid for by monthly premiums of Medicare enrollees.

Medicaid

Medicaid is a program that provides healthcare coverage for low-income families and individuals, for persons with disabilities, and in some cases the elderly. For medical billing purposes, the most important difference between Medicare and Medicaid is the organization of each program. Medicare is a program provided by the federal government through CMS and has universal applications across state boundaries. Medicaid is a program funded by both state governments and the federal government. States provide Medicaid benefits in cooperation with CMS and federal guidelines. Medicaid programs differ from state to state, though they must all meet certain standards established by the federal government.

Medicaid coverage plans can change from state to state. Some states have extended their Medicaid programs to cover comprehensive healthcare issues for recipients, while other states only meet the minimum program requirements as mandated by the federal government. The following are some of the minimum Medicaid services covered:

• Inpatient/outpatient hospital services
• Family planning care
• Pediatric services
• Prescription drug costs
• Dental healthcare and services
• Mental health services
• Occupational, physical, and speech therapy

Rules of Medicaid eligibility also vary by state. Some states have stricter rules for eligibility, while others are more relaxed. As a medical billing specialist you should understand Medicaid eligibility in your state.
