Antibiotic infusion therapy plays a critical role in modern infectious disease management. Among the newer options, Dalvance (dalbavancin) stands out because it offers a long-acting, two-dose regimen that can treat acute bacterial skin and skin structure infections (ABSSSI) without requiring daily intravenous access. However, the unique dosing schedule and intravenous route create very specific coding questions. Healthcare providers, medical coders, billers, and revenue cycle professionals frequently ask one central question: what is the correct CPT code for a Dalvance infusion?
This article answers that question in depth. It covers the primary CPT codes, documentation requirements, site-of-care considerations, payer policies, reimbursement nuances, and common mistakes to avoid. You will also find comparison tables, a full FAQ, and practical tips to ensure clean claims.
Understanding Dalvance and Its Clinical Use
Dalvance is the brand name for dalbavancin, a lipoglycopeptide antibiotic. The FDA approved it for the treatment of acute bacterial skin and skin structure infections caused by susceptible Gram-positive organisms, including MRSA (methicillin-resistant Staphylococcus aureus).
A distinguishing feature of Dalvance is its extended half-life, which allows a two-dose regimen one week apart. This often eliminates the need for daily infusions or a long-term central line. The standard dosing is a 1500 mg intravenous infusion on day one, followed by a 500 mg intravenous infusion on day eight. A single-dose 1500 mg regimen is also recognized in certain clinical scenarios.
Because each dose requires intravenous administration over 30 minutes, the infusion itself becomes a billable service in most settings. This is where CPT coding becomes essential.
Why Correct CPT Coding for Dalvance Infusion Matters
Billing for medication and billing for drug administration are two separate activities in U.S. healthcare. You bill the drug itself using a HCPCS code (typically J-code). You bill the service of administering the drug using a CPT code.
Coding errors in either area can lead to:
- Claim denials
- Delayed payments
- Increased audit risk
- Underpayment or overpayment
- Compliance violations
Understanding the correct CPT code for the infusion service protects your practice’s revenue cycle and keeps documentation aligned with payer expectations.
The Primary CPT Code for Dalvance Infusion
The Core Administration Code
Dalvance is administered as an intravenous infusion. The Current Procedural Terminology (CPT) code set defines specific codes for therapeutic intravenous infusions based on the duration of the infusion and whether it is the initial service or an additional sequential infusion.
For Dalvance, the standard administration time is 30 minutes. This places it squarely within the definition of a therapeutic infusion.
The correct CPT code for the initial intravenous infusion of Dalvance is:
CPT 96365 – Intravenous infusion, for therapy, prophylaxis, or diagnosis (specify substance or drug); initial, up to 1 hour
This code covers the first hour of a therapeutic infusion. Because the Dalvance infusion lasts 30 minutes, you bill one unit of 96365.
You report CPT 96365 once per encounter as the primary or initial infusion service. The documentation must clearly state the start and stop times of the infusion, the drug name, the dose, and the route.
Why 96365 Instead of Other Infusion Codes
The CPT manual organizes therapeutic infusions by hierarchy:
- 96365: Initial infusion, up to 1 hour
- 96366: Each additional hour of the same infusion
- 96367: Additional sequential infusion of a new drug or substance, up to 1 hour
- 96368: Concurrent infusion of a new drug or substance
Dalvance is typically the sole infusion drug given in a single encounter. You do not need an add-on code for additional hours because the infusion does not exceed 60 minutes. You also do not use 96367 unless another therapeutic substance follows the Dalvance infusion.
Is an Injection Code Ever Appropriate for Dalvance?
This is a common point of confusion. Some staff confuse intravenous push (IVP) injections with slow IV infusions. Dalvance requires dilution and administration over 30 minutes. It is not given as a rapid IV push.
Because the administration exceeds 15 minutes and uses an infusion pump or gravity drip, it is an infusion, not an injection. You should never code Dalvance administration using injection codes such as:
- 96374 (Therapeutic, prophylactic, or diagnostic injection; intravenous push)
- 96372 (Therapeutic injection; subcutaneous or intramuscular)
Using an injection code for a 30-minute infusion would misrepresent the service and could trigger a payer audit.
When Dalvance Is the Second Drug in an Encounter
Some patients receive pre-medications, antiemetics, or another antibiotic before the Dalvance infusion. In this scenario, the first drug administered typically claims the initial code (96365). Dalvance then becomes an additional sequential infusion.
The correct code for Dalvance when it follows another therapeutic infusion is:
CPT 96367 – Intravenous infusion, for therapy, prophylaxis, or diagnosis; additional sequential infusion of a new drug/substance, up to 1 hour
In this case, you would also bill 96365 for the first drug. Both drugs must be documented with separate start and stop times. The medical record should clearly reflect the sequence.
Chemotherapy Infusion Codes Are Not Appropriate
Some coders wonder whether Dalvance falls under chemotherapy administration codes. Dalvance is an antibiotic, not an antineoplastic agent. It has no FDA-approved indication as chemotherapy. You should never use codes from the 96401–96549 range for Dalvance. Doing so is a coding error that payers will reject or audit.
HCPCS Coding for the Dalvance Drug Itself
While this article focuses on CPT administration codes, you cannot bill for the infusion without also billing for the drug product, when applicable. You report the drug supply with a HCPCS Level II code.
The established HCPCS code for dalbavancin is:
J0875 – Injection, dalbavancin, 5 mg
Dalvance comes as a 500 mg single-dose vial. Each 500 mg vial contains 100 units of J0875 (500 mg divided by 5 mg per unit equals 100 units). For a 1500 mg dose, you would bill 300 units of J0875.
Always verify current HCPCS pricing and coverage with your MAC (Medicare Administrative Contractor) or commercial payer. J-code billing does not replace CPT billing; it accompanies it.
Site-of-Care and CPT Code Application
Hospital Outpatient Department
In the hospital outpatient setting, you report CPT codes for drug administration according to OPPS (Outpatient Prospective Payment System) rules. Infusion services often package into the visit or procedure, depending on status indicators.
For Dalvance, the hospital outpatient department typically reports:
- CPT 96365 for the infusion service
- J0875 for the drug supply
- Any evaluation and management (E/M) service if separately provided and medically necessary
The infusion CPT code may or may not generate separate payment, but you must still report it accurately for statistical and compliance purposes.
Physician Office or Freestanding Infusion Center
In an office-based infusion suite, CPT administration codes are separately payable under the Medicare Physician Fee Schedule or commercial fee schedules. Reporting 96365 accurately directly affects practice revenue. Failure to include the infusion code means the practice only bills for the drug, missing the administration payment.
Home Infusion
Home infusion presents special coding challenges. A home health agency may provide nursing services to administer Dalvance in the patient’s home. In that scenario, the agency may bill CPT administration codes under Part B, depending on payer policy. The home health nurse documents the infusion details, and the billing entity submits the claim.
Some private payers have specific contracts for home infusion services with per diem rates rather than fee-for-service CPT codes. Always verify before submitting the claim.
Documentation Essentials for CPT 96365
Solid documentation protects your claim and withstands audits. For every Dalvance infusion, make sure the medical record includes:
- Physician order for the infusion with the drug name and dose
- Nursing notes with the exact start and stop times of the infusion
- Route of administration (intravenous)
- Infusion rate or total duration
- Patient tolerance and any adverse reactions
- Lot number and expiration date of the drug (often required by hospital policy)
The start time and stop time are especially critical. They establish that the infusion lasted 30 minutes and that CPT 96365 is the correct code.
Coding for the Two-Dose Dalvance Regimen
The standard Dalvance regimen involves two infusions separated by one week. Each encounter is billed independently with the appropriate date of service.
- Day 1: 1500 mg infusion over 30 minutes → report 96365 and J0875 x 300 units
- Day 8: 500 mg infusion over 30 minutes → report 96365 and J0875 x 100 units
Each infusion qualifies as an initial service for that date because they occur on different days. You do not need to use an add-on code for the second visit.
Single-Dose Dalvance Regimen Coding
In some protocols, clinicians use a single 1500 mg dose of Dalvance without the day 8 booster. The coding follows the same logic:
- Single encounter: 1500 mg over 30 minutes → CPT 96365, J0875 x 300 units
The absence of a second visit simplifies the billing but does not change CPT selection.
Common Coding Errors and How to Avoid Them
1. Reporting 96374 (IV Push) Instead of 96365
An IV push is a rapid injection. Dalvance given over 30 minutes is never a push. The provider’s order and nursing documentation must clearly state “infusion over 30 minutes” or “infuse at X mL per hour.” If an auditor sees an IV push claim for a drug that requires dilution and slow infusion, the claim could be flagged as fraudulent.
2. Billing Units of 96365 Based on Dose
CPT 96365 is billed per encounter, not per milligram. Some billers mistakenly attempt to bill multiple units of 96365 for a 1500 mg dose. You bill one unit of 96365 regardless of whether the dose is 500 mg or 1500 mg, as long as the infusion duration stays within one hour.
3. Omitting the J-Code on the Claim
When the practice purchases the drug, you must include the J-code for payment. If you omit J0875, the payer may deny the claim or pay only for the infusion. If a third party supplies the drug, verify whether the payer still requires the J-code for tracking.
4. Using Hydration Infusion Codes
Hydration CPT codes (96360-96361) describe the administration of fluids and electrolytes, not therapeutic antibiotics. Never report Dalvance administration with hydration codes.
5. Confusing 96365 with Prolonged Infusion Codes
Prolonged infusion codes apply when therapeutic infusion requires more than one hour. Dalvance infusions do not cross this threshold. Do not append 96366.
Comparison Table: Correct vs. Incorrect CPT Codes for Dalvance
| Scenario | Correct Code | Incorrect Codes to Avoid | Reason |
|---|---|---|---|
| Initial Dalvance infusion, 30 minutes | 96365 | 96374, 96372 | 96365 defines a therapeutic infusion; Dalvance is given as a slow IV infusion |
| Dalvance as second infusion after another drug | 96367 | 96365 (if first drug already claimed 96365) | Sequential rule requires first drug as initial and second drug as sequential |
| Dalvance drug supply | J0875 | J3490, J3590 (unlisted codes) | J0875 is the specific code for dalbavancin |
| Two-dose regimen, one week apart | 96365 for each visit | One 96365 “covering” both days | Each date of service is independent |
Medicare Coverage and Billing Considerations
Medicare covers Dalvance when medically necessary for FDA-approved or compendia-supported indications. The infusion service falls under either Part B (outpatient or physician office) or Part A (inpatient hospital stay).
For Medicare Part B claims:
- Use the CMS-1500 form for physician offices
- Assign the appropriate diagnosis code (e.g., L03.119 for cellulitis of unspecified part of limb)
- Link the diagnosis to the infusion CPT code and drug HCPCS code
- Report units of J0875 accurately
Local Coverage Determinations (LCDs) may exist. Always check your MAC’s website for dalbavancin-related policies. Some LCDs require specific documentation of the infection type, culture results, or prior treatment failure.
Commercial Payer Policies
Private insurers vary widely in their Dalvance coverage rules. Many require prior authorization. Some designate Dalvance as a medical benefit drug (covered under the medical benefit rather than the pharmacy benefit). In those cases, the infusion CPT code and J-code appear on a medical claim.
Key steps for commercial payers:
- Verify benefits and obtain prior authorization before scheduling the infusion
- Confirm whether the payer considers Dalvance under the medical or pharmacy benefit
- Confirm whether the practice may buy-and-bill the drug or must obtain it through a specialty pharmacy
- Document authorization numbers on the claim
If a specialty pharmacy ships the drug directly to the provider, the practice does not bill the J-code but still bills the administration CPT code. The pharmacy bills the payer for the drug product. This split billing arrangement reduces the practice’s financial risk but requires careful coordination.
Hospital Inpatient Coding for Dalvance
When a patient receives Dalvance during an inpatient hospital stay, CPT administration codes are not used for the hospital claim. Instead, the inpatient facility reports ICD-10-PCS procedure codes.
The ICD-10-PCS code for Dalvance infusion is:
3E03329 – Introduction of Other Anti-infective into Peripheral Vein, Percutaneous Approach
This code applies when you infuse an antibiotic through a peripheral IV line. The hospital also includes the drug cost in the DRG payment. The professional fee for the ordering physician may be billed separately using the appropriate E/M codes.
Infusion Coding in the Emergency Department
Some patients receive the first dose of Dalvance in the emergency department before discharge or admission. The emergency department reports facility infusion CPT codes just as any hospital outpatient department would. CPT 96365 remains the correct initial infusion code. If the patient is discharged home after the infusion, the ED visit E/M level plus the infusion code are reported. The drug cost falls under hospital outpatient billing.
Documentation Templates to Support Coding
A structured documentation template improves accuracy and audit resilience. Below is an example of a nurse infusion note that supports CPT 96365:
Infusion Note
Date: [mm/dd/yyyy]
Patient: [Name]
Ordered by: [Provider]
Drug: Dalvance (dalbavancin) 1500 mg in 1000 mL D5W
Route: Intravenous
Infusion start: 09:00
Infusion stop: 09:30
Total duration: 30 minutes
Site: Left forearm, 22 gauge peripheral IV
Vital signs: Pre-infusion BP 128/78, HR 72; Post-infusion BP 126/76, HR 74
Patient tolerated infusion well. No signs of extravasation or allergic reaction.
Nurse signature: [Name, credentials]
This note explicitly includes the required start and stop times and confirms the 30-minute duration.
Patient Financial Considerations
Dalvance can be expensive. Many patients worry about cost. A guide for your billing team to share with patients includes:
- Verify whether the patient’s insurance covers Dalvance under the medical benefit
- Inform the patient about potential copayment or coinsurance for the infusion visit
- Discuss patient assistance programs offered by the manufacturer
- For uninsured patients, explore free drug programs or sliding-scale clinic fees
Transparent financial discussions build trust and prevent surprise bills.
Billing for Infusion Observation Time
Dalvance infusion sometimes includes monitoring for an additional 30 to 60 minutes post-infusion to observe for hypersensitivity reactions. This observation time is not separately billable in the outpatient setting. It falls under the infusion service itself. Do not attempt to report E/M codes solely for monitoring unless a separately identifiable evaluation occurs.
If the patient develops a reaction that requires medical intervention, the provider may document a distinct E/M service with modifier 25. The documentation must clearly separate the problem-oriented E/M service from the routine infusion monitoring.
Modifier Use with CPT 96365 for Dalvance
Most Dalvance infusion claims do not require modifiers. However, certain situations call for modifier application.
Modifier 25
Attach modifier 25 to a separately identifiable E/M service provided on the same day as the infusion. The E/M note must stand alone as medically necessary and beyond routine pre-infusion assessment.
Modifier 59
Rarely needed for Dalvance. In the unlikely event that two separate intravenous infusions occur during different time blocks and one is not sequential to the other, modifier 59 might distinguish them. This scenario is unusual in routine Dalvance administration.
Modifier JW
If a vial of Dalvance is partially used and the remainder is discarded, you must report the discarded amount with modifier JW on the J-code line. For example, if a 500 mg single-dose vial is used for a 500 mg dose with no wastage, no JW modifier is needed. If a 500 mg vial is opened for a 1500 mg dose and only 500 mg of a fourth vial is used, the remaining drug is wasted and must be documented and billed accordingly. Proper JW modifier usage maintains compliance and may allow payment for the discarded amount under some payer policies.
Audit Risks and How to Prepare
Infusion coding is a known area of focus for the Office of Inspector General (OIG) and Recovery Audit Contractors. Preparing your practice for potential audits involves:
- Maintaining clear policies on infusion start/stop time documentation
- Regular internal audits of infusion claims against nursing notes
- Training clinical staff on required documentation elements
- Keeping signed physician orders on file
- Tracking lot numbers and drug wastage logs
Proactive compliance reduces clawback risk and protects revenue.
Infusion Coding in Value-Based Arrangements
As healthcare moves toward value-based care and bundled payments, accurate CPT coding remains foundational. Even when a payer uses an episode-of-care payment, the codes you report drive data analytics and quality measurement. Inaccurate coding distorts performance metrics and can harm your position in shared savings programs.
Dalvance, as a relatively new therapy, is often tracked by payers to evaluate outcomes and cost-effectiveness. Reliable coding helps build the evidence base for appropriate antibiotic stewardship.
Coding for Pediatric Dalvance Use
Dalvance is not FDA-approved in pediatric patients, but off-label use occurs in some settings. When a provider administers Dalvance to a child, the same CPT administration codes apply. The J-code remains J0875. Payers may require additional documentation of medical necessity for off-label use. Check your payer’s policy on off-label dalbavancin for pediatric patients before submitting the claim.
The Role of Clinical Documentation Improvement (CDI)
CDI specialists review records to ensure they accurately reflect the services delivered. For Dalvance infusion, CDI may query the provider when:
- The order does not specify infusion duration
- The nursing note lacks start and stop times
- The diagnosis does not support an anti-MRSA antibiotic
- There is no documentation of infection type or pathogen
Collaboration between CDI, coding, and clinical staff improves claim accuracy and reduces denials.
Comparison Table: Infusion vs. Injection vs. Hydration Codes
| Service Type | CPT Code Range | Example | When to Use |
|---|---|---|---|
| Therapeutic IV Infusion (initial, up to 1 hr) | 96365 | Dalvance over 30 min | Drug requires slow IV drip over more than 15 minutes |
| Therapeutic IV Infusion (additional hour) | 96366 | Continuation beyond 60 min | Not applicable for standard Dalvance |
| Additional sequential infusion | 96367 | Second antibiotic after first | Only when another drug is infused first |
| IV Push Injection | 96374 | Furosemide IV push over 2 min | Rapid administration of single dose |
| Hydration | 96360-96361 | Normal saline 1000 mL | Pre-hydration or maintenance fluids only |
| Chemotherapy Infusion | 96413-96417 | Rituximab | Antineoplastic or biologic agents for cancer or autoimmune disease |
Key Points and Important Notes
Important Note: Always verify with your specific payer and MAC for any local coverage policies or prior authorization requirements before administering Dalvance. Coding policies may evolve.
Critical Reminder: CPT 96365 requires documentation of the substance administered. Write “Dalvance (dalbavancin)” clearly in the record. Never use generic “IV antibiotic” shorthand.
Wastage Billing Tip: If you waste part of a Dalvance vial, document the exact amount discarded and use the JW modifier on the J-code line. Missing this step can lead to lost reimbursement or compliance issues.
