Injection: A method of delivering medication directly into the body using a needle
and syringe. Injections are typically quick procedures, often administered
intramuscular (IM), subcutaneous (SC), or intravenous (IV).
Infusion: The process of administering fluids, medications, or nutrients directly into
the bloodstream over a period of time, usually through an IV line. Infusions can be
continuous or intermittent.
Common Clinical Uses
Vaccinations and allergy injections
Administering antibiotics, chemotherapy, or hydration fluids
Biologic therapies and monoclonal antibodies
Blood products and plasma exchange

Key Coding Principles for Injection and Infusion Services
Accurate coding hinges on understanding the CPT (Current Procedural Terminology)
guidelines, proper documentation, and differentiating between the various types of
procedures.
2
Identifying the Appropriate CPT Codes
Injection codes: Typically found in CPT codes 96372–96375, 96401–96450, and
others depending on the type and site.
Infusion codes: Usually in CPT codes 90765–90768, 96360–96379, and
96413–96416, among others.
Documentation Requirements
To ensure proper reimbursement and compliance, the following must be clearly
documented:
Type of procedure performed (injection or infusion)
Site and route of administration
Type and dosage of medication administered
Duration of infusion, if applicable
Patient's response and any adverse reactions
Understanding Modifier Use
Modifiers are essential when billing multiple procedures, staged treatments, or procedures
performed on multiple sites. For example:
Modifier 59: Distinguishes separate procedures
Modifier 76: Repeat procedure by same provider
Modifier 77: Repeat procedure by another provider

Guidelines for Coding Injections
Use the base CPT code that corresponds to the route and site of administration.
When multiple injections are given during the same session, report each injection
separately, unless specified as bundled.
Document the drug name, dosage, and site for each injection.
For IV push and infusion, specify the number of drugs administered and the duration
of the procedure.
Special Considerations
For allergy injections, use specific codes that reflect the number of allergens and
visits.
When administering multiple injections in different sites, ensure each is properly
documented and billed accordingly.
