CPT® Code 96374

Quick Reference: CPT 96374 (Initial IV Push)

• What 96374 means: Therapeutic, prophylactic, or diagnostic intravenous push administration, single or initial substance/drug in a session. It describes a rapid IV administration (bolus) performed by clinical staff with patient monitoring. The drug itself is billed separately.
• IV push time definition: An IV push is either a true syringe/bolus injection or a short infusion lasting 15 minutes or less. CPT/CMS guidance treats a 15-minute-or-less infusion as a push rather than a timed infusion hour.
• Only one "initial" per encounter (usually): Under the drug administration hierarchy, you generally bill one initial code per encounter (per IV access site). Additional services are typically coded with add-on codes (e.g., 96375) rather than repeating 96374. MAC guidance emphasizes hierarchy-based "initial" selection even if the chronological order differs.
• Hierarchy matters: In non-chemotherapy services, therapeutic infusions generally outrank IV pushes, and IV pushes outrank IM/subQ injections and hydration. Therefore, an infusion may become the "initial" service even if the push occurred first.
• Facility vs non-facility billing: In hospital outpatient/ED settings, the facility typically bills drug administration codes; physicians generally do not report 96360-96379 for facility services. NCCI policy includes explicit direction on this site-of-service limitation.
• Modifier essentials: Modifier 25 may be used on E/M when a significant, separately identifiable visit occurs on the same date as the IV push. Modifier 59 (or X{E,S,U,P} when accepted) may be necessary to override certain NCCI edits or to identify a distinct encounter/site.

CPT 96374 is one of the most commonly used non-chemotherapy drug administration codes, yet it is also one of the most frequently miscoded. Most payment and audit risk comes from three avoidable problems: (1) confusing IV push with IV infusion (especially around the 15-minute threshold), (2) billing more than one "initial" service without a documented separate encounter or IV site, and (3) billing the code on the wrong claim type (professional vs facility) based on place of service. This article provides a 2026-focused, payer-realistic approach to using 96374 compliantly and defensibly.

1. Clinical Definition and Procedure Scope

CPT 96374 is defined as: therapeutic, prophylactic, or diagnostic injection (specify substance or drug); intravenous push, single or initial substance/drug. The code represents the administration service -- not the medication itself -- and is intended for rapid IV delivery in a controlled, observed clinical interaction.

In operational terms, an IV push typically involves one of the following:

• Manual push (bolus): Medication is administered via syringe directly into venous access (peripheral IV, port, etc.) over a short period, often seconds to a few minutes.
• Short infusion treated as a push: Medication is delivered via tubing or syringe pump but the total administration time is 15 minutes or less, which is coded as a push per CMS/CPT definitions for drug administration services.

Included services: As with most drug administration codes, routine components necessary to deliver the push are packaged into the administration code (for example, typical supplies and routine clinical labor associated with administration). CMS coding policy emphasizes bundling of integral services within the administration family, including the baseline office-clinic nursing work that overlaps with minimal visit work.

Not included: 96374 does not include the medication (bill separately using the applicable HCPCS drug code), and it does not substitute for chemotherapy administration codes when chemotherapy/other highly complex agents are involved. It is also not the correct code for IM/subQ injections (use 96372) and is not used when the service is actually a timed infusion beyond the push threshold (typically >15 minutes for the substance being administered, then evaluate infusion codes and time rules).

Practical boundary: If your documentation supports that the drug ran for more than 15 minutes, auditors expect infusion logic to be considered. If your documentation cannot support an infusion duration (for example, missing stop time), payer guidance often forces conservative coding -- commonly down to push-level reporting.

2. CMS Billing Rules and Infusion Hierarchy

CMS and CPT apply a structured hierarchy to determine which drug administration code is "initial," which are "additional," and when separate "initial" codes are permissible. While details vary across claim types, the underlying principle is consistent: the "initial" code is the highest-ranked service within the encounter, not necessarily the first chronologically administered drug.

2.1 The hierarchy (conceptual)

flowchart TD
    A[Multiple Drug Admin Services in One Encounter] --> B{Identify Highest-Ranked Service}
    B --> C[Therapeutic/Diagnostic Infusion > 15 min]
    B --> D["IV Push (15 min or less)"]
    B --> E[IM/SubQ Injection]
    B --> F[Hydration]
    C --> G[Report as INITIAL service]
    D --> H{Is there a higher-ranked service?}
    H -->|Yes| I[Report IV push as ADD-ON / sequential]
    H -->|No| J[Report 96374 as INITIAL]
    E --> K[Report as add-on or use modifier 59 if distinct]
    F --> L[Report as add-on if above minimum time threshold]
    G --> M[All other services become sequential/add-on codes]

In non-chemotherapy services, the hierarchy generally follows this order:

• Therapeutic/prophylactic/diagnostic infusions (higher)
• IV pushes (mid)
• IM/subQ injections (lower)
• Hydration (often lowest in mixed encounters)

CMS article guidance for infusion/injection/hydration services explains that infusion is primary, then injections/IV pushes, then hydration -- an ordering that drives initial code selection and add-on usage.

2.2 One "initial" per encounter (with limited exceptions)

MAC guidance and payer coding manuals emphasize that you generally report one initial service per encounter (often per venous access site). When multiple services occur through the same line in one session, the highest-ranked service becomes the initial code and other services become add-ons/sequential services.

Exception: A second initial code may be appropriate when there are distinct IV access sites used for medically necessary reasons or distinct encounters on the same date. Commercial payer guidance similarly notes modifier use to identify separate sites/encounters when multiple initials are appropriate.

2.3 Short infusion coded as push

CMS infusion/injection guidance explicitly defines IV push to include an infusion lasting 15 minutes or less. This rule prevents inappropriate "first hour infusion" reporting for short administrations.

In practical coding audits, time is the pivot. When a record shows a medication ran for 10-15 minutes, coders should default to push logic (96374 for the initial push in that encounter, or the relevant add-on push code when a higher service is initial). When a record shows a medication ran longer, coders should evaluate infusion codes and the time thresholds for initial and additional hours.

2.4 CMS implementation and claim processing

CMS operationalizes these rules via edit logic (including NCCI policy and MAC billing guidance), which affects denials and payment packaging. For example, certain combinations that appear to represent two "initial" services in one session are commonly denied or recoded unless a separate encounter/site is clearly documented and correctly modified.

3. Facility vs Non-Facility Payment Policies

Correct billing of 96374 depends heavily on place of service and whether the service is billed on a professional claim or a facility claim. The risk is not theoretical: NCCI policy explicitly addresses physician reporting restrictions for these drug administration codes in facility environments.

3.1 Physician office/clinic (non-facility) billing

In a physician office or clinic setting, 96374 may be reported on the professional claim when the practice provides the clinical labor and supplies. Medicare "incident-to" requirements typically apply when non-physician staff perform the push under appropriate supervision, and payer policies often treat the routine pre-injection assessment as included in the injection administration service. NCCI policy notes that the drug administration family is valued to include work overlapping minimal visit-level activity, which is relevant when deciding whether to bill an additional low-level E/M.

3.2 Hospital outpatient / emergency department (facility) billing

In hospital outpatient and ED settings, drug administration services are typically billed by the facility (e.g., on the UB-04 / institutional claim). NCCI policy states that these codes should not be reported by physicians for services provided in a facility setting such as a hospital outpatient department or ED.

Practically, this means:

• Facility claim: Reports the administration code(s) for nursing and facility resources.
• Professional claim: Physician reports the E/M and other professional services, not the administration code.

Commercial policies may echo this logic in their payment rules. For example, Medicare Advantage policies may specify that in certain facility places of service, the injection administration is not separately reimbursed to the physician when an E/M is billed, because the facility is paid for the administration work.

3.3 CMS transmittals and operational updates

CMS transmittals periodically clarify operational billing rules and instructions across settings. For infusion/injection services, these documents can affect how claims are edited and paid even when underlying CPT concepts remain stable.

4. Modifier Usage and NCCI Edits

Modifiers are not decorative; they are the mechanism by which claims systems distinguish legitimate separate services from duplicative billing. For 96374, the highest-yield modifier decisions involve (a) whether an E/M service is separately billable, and (b) whether multiple administration services in the same session are distinct or bundled under hierarchy and NCCI edits.

4.1 Modifier 25 on E/M

When a provider performs a significant, separately identifiable E/M service on the same date as an IV push, modifier 25 may be appended to the E/M code. This is appropriate when the clinical evaluation is beyond the routine pre-administration work (review of allergies, consent, vitals, basic monitoring) that is considered part of the injection/infusion service. NCCI policy and payer reimbursement guidance discuss the overlap between drug administration services and minimal E/M-type work, which is why careful documentation is essential when using modifier 25.

4.2 Modifier 59 (or X-modifiers) for distinct services

Modifier 59 (or an appropriate X-modifier when accepted) is used to indicate a distinct procedural service -- commonly a separate site, separate encounter, or separate service not otherwise captured by hierarchy logic. This is frequently relevant in drug administration when a secondary injection is bundled into a higher-ranked service by NCCI edits, or when a second "initial" is billed on the same date for a distinct encounter or medically necessary separate IV access site.

Common edit scenario: IM/subQ injection (96372) may bundle into an IV push (96374) when performed in the same session because the IV push represents a higher-ranked service. When both were truly performed and are clinically distinct (different drug, different route/site), modifier 59 on the lower-ranked service may be required to receive separate payment, subject to payer policy.

4.3 Modifier 76 and repeat services (professional claims)

Modifier 76 (repeat procedure by same provider) is not the standard approach for routine additional pushes because CPT provides add-on codes for sequential administrations. The question arises primarily when a second administration of the same drug occurs in an office setting and no distinct add-on mechanism exists on the professional side that perfectly matches the facility add-on model. In these cases, payer-specific policy controls: some may accept repeat reporting with modifier 76, others may not. When used, documentation must clearly show two separate clinical administrations and their necessity.

4.4 Avoiding modifier misuse

From a compliance standpoint, the highest-risk modifier misuse patterns are:

• Using 59 to "force pay" when services are not actually distinct.
• Using 25 reflexively for every injection visit without separately identifiable evaluation documentation.

Both patterns are common audit triggers because they suggest billing strategy rather than documentation-driven coding. CMS and payer policies are clear that modifiers must be supported by the medical record, including separate notes or clearly distinct documentation elements.

5. Documentation Standards

For 96374, documentation must support: (1) that an IV push occurred, (2) which drug and dose were administered, (3) that the administration meets the push definition (including the 15-minute-or-less logic where relevant), (4) the clinical indication, and (5) the correct assignment of initial vs additional services when multiple administrations occur. CMS billing and coding guidance for infusion/injection/hydration services emphasizes time and sequencing clarity, and NCCI policy explains how bundled work affects separate billing.

5.1 Minimum documentation elements

• Medication and dose: Name, strength, and total administered dose (e.g., "metoclopramide 10 mg").
• Route and method: Explicitly state "IV push" (not just "given"); include site/line as relevant (peripheral IV, port, etc.).
• Time of administration: At minimum, administration time (HH:MM). If the drug ran as a short infusion, note start/end or duration (e.g., "ran 12 minutes").
• Clinical indication: Link to the condition being treated/prevented/diagnosed (e.g., "for nausea," "for acute pain").
• Monitoring/response (best practice): Record vitals, adverse reaction monitoring, or patient response when clinically relevant.
• Who administered and supervision context: Identify the administering professional (RN/LPN/MD) and, in office settings, supervision context consistent with payer rules.

5.2 Documentation to support hierarchy and add-on use

When multiple administrations occur, documentation should make it easy to determine whether 96374 is the initial service or whether another service (e.g., therapeutic infusion) is the initial and the push is a subsequent/add-on. MAC guidance discusses this hierarchy selection approach, which is frequently misapplied when coders use "first in time" rather than "highest in hierarchy."

For sequential administrations of different substances, record each administration as a separate event. This supports correct use of add-on codes (such as 96375) when appropriate.

7. Real-World Clinical Scenarios

Scenario 1: ED IV push diuretic for acute CHF

Setting: Hospital ED (facility environment). Service: Furosemide administered IV push over ~2 minutes with monitoring; patient then treated further. Coding logic: Facility reports 96374 for the IV push; the professional claim generally reports E/M only. NCCI policy addresses that physicians should not report these administration codes for facility services. Documentation tip: Record the drug/dose, IV push method, and administration time; monitor and note response.

Scenario 2: Short antibiotic administration (15 minutes or less) before discharge

Setting: Hospital outpatient/ED or infusion clinic. Service: Ceftriaxone delivered over ~10 minutes. Coding logic: Because the administration is 15 minutes or less, it meets the IV push definition per CMS infusion/injection guidance and is coded as a push rather than an initial infusion hour. Common error avoided: Reporting a first-hour infusion code for a short "mini-bag" run without time support.

Scenario 3: Infusion encounter with pre-med IV pushes

Setting: Outpatient infusion suite. Service: Patient receives a therapeutic infusion (primary service) and also receives sequential IV pushes of two different pre-medications. Coding logic: The therapeutic infusion is often the initial service in hierarchy, with IV pushes reported as sequential/add-on administrations rather than as the initial push. MAC guidance emphasizes hierarchy-based initial selection over "first in time" selection.

Scenario 4: Office migraine treatment with both IV push and IM injection

Setting: Physician office (non-facility). Service: IV push antiemetic + IM NSAID for migraine. Coding logic: 96374 for the IV push; 96372 for the IM injection. If payer edits bundle 96372 into the higher-ranked IV push, a distinctness modifier may be needed for the IM injection when supported (different route/site and clinically distinct). NCCI policy explains bundling and the need for documentation-driven modifier use. E/M: If a separately identifiable office visit is performed beyond routine pre-administration work, report E/M with modifier 25 and ensure documentation supports distinct clinical evaluation.

Scenario 5: Two separate encounters on the same date

Setting: Non-facility clinic with two visits (morning and afternoon). Service: IV push administered in the morning; patient returns later for a separate, medically necessary IV push session. Coding logic: Two initial services on one date may be payable only when a distinct encounter is documented and properly indicated. Commercial payer coding guidance describes the use of modifier 59/XE to indicate separate sessions when appropriate. Documentation tip: Separate note for the second encounter with its own medical necessity and time context.
