Chapter 8
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
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
Injections and Infusions:
Immune Globulins
• Immune globulins provide protection
against certain diseases
• Immune globulin administration (90765–
90775)
– Intramuscular
– Subcutaneous
– Intravenous
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
Injections and Infusions:
Hydration
• Hydration: administration of prepackaged
fluid and electrolytes (not drugs)
– Codes are based on time
• 90760 – one hour
– 90760 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 90761
• 90761 – add-on for each additional hour
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
