Introduction to Medicine Procedures and Services

1. Chapter 8 Medicine

2. Introduction • Diagnostic, therapeutic, and miscellaneous procedures and services • Health-care providers other than physicians have unique service codes • Special service codes • i.e., outside of normal office hours

3. Common Modifiers • -25 • Separately identifiable evaluation and management service by the same physician on procedure day • -50 • Service code represents unilateral procedure, it is provided bilaterally • -52 • Services provided are less than the full code describes • -59 • Encounter has occurred on the same day and codes have already been billed for those services

4. Injections and Infusions:Immune Globulins • Immune globulins provide protection against certain diseases • Injections • Intramuscular • Subcutaneous • Intravenous

5. Injections and Infusions:Vaccination and Toxoid Administration • Immunity: body produces antibodies in response to antigen exposure • Antigens: Bacteria, viruses, fungi • Route of administration • Percutaneous • Intradermal • Subcutaneous • Intramuscular • Intranasal • Oral • Age of patient • Number of administrations: Add-on codes for “each additional” • Two codes are required: Administration and vaccine or toxoid product injected

6. Injections and Infusions: Hydration • Hydration: administration of prepackaged fluid and electrolytes (not drugs) • Codes are based on time • 96360 – one hour • 96360 should not be used as the initial service if a patient is also treated with a medication • Example: Patient with nausea and vomiting receives IV fluids and then Phenergan IV push (through the IV). Code Phenergan administration as the initial service and fluids as 96360 • 96361 – add-on for each additional hour

7. Injections and Infusions • Therapeutic, prophylactic, and diagnostic • Codes based on route and time • First hour, each additional hour • Medication supply codes: depends on payer requirements • Assign a “J” code from HCPCS Level II • If payer will not accept “J” code, assign 99070
