Quick Answer: What Are CPT 96365, 99360, and 99366?
CPT 96365 is used for the first IV infusion given for treatment, prevention, or diagnosis. The infusion must last more than 15 minutes and up to 1 hour. CPT 99360 is used for standby services that need extended attendance like during a high-risk cesarean delivery. CPT 99366 is used for medical team meetings with the patient or family that last at least 30 minutes and are led by a qualified nonphysician healthcare professional. Medicare generally pays for 96365 when it is documented correctly but it does not pay separately for 99360 or 99366.
How the Three Codes Fit Together
CPT 96365, 99360, and 99366 cover different services but all require accurate time tracking and clear documentation. CPT 96365 is commonly reimbursed when billing rules are met while CPT 99360 and 99366 are not paid separately by insurance. Choose the code based on the service provided. A 45-minute IV antibiotic infusion uses 96365 while a two-hour infusion uses 96365 and 96366. A different drug infused through the same line requires 96367 while a 10-minute IV push uses 96374.
Always verify codes in the current-year AMA CPT code set or a coding tool before billing. Because invalid codes can lead to claim rejections, payment delays, and extra work.

CPT 96365: Initial IV Infusion
Official Definition of CPT 96365
CPT 96365 is used for the initial IV infusion of a drug or substance for treatment, prevention, or diagnosis. The infusion can last up to one hour under the code’s definition. It has been in CPT since 2009 and remains an active code for 2026, with no change to its description.
What Qualifies for CPT 96365?
- IV medication: Used for non-chemotherapy medications, such as IV antibiotics, monoclonal antibodies, IV iron, and immune globulin (IVIG).
- Infusion time: The infusion must last longer than 15 minutes. Services lasting 15 minutes or less can qualify as an IV push using code 96374.
- Required documentation: The medical record should include the provider’s order, drug name, dose, and infusion start and stop times.
- Other types of infusions: Chemotherapy and certain complex drug treatments use different codes, such as 96413. IV hydration uses codes 96360 and 96361.
How to Code Based on Infusion Time
- 15 minutes or less: Use IV push code 96374 when the service meets its requirements, not 96365.
- 16 to 90 minutes: Report 96365 once. Under CPT timing rules, an infusion lasting up to 90 minutes generally counts as one unit.
- 91 minutes or longer: Report 96365 and add-on code +96366 when the additional infusion time meets the applicable requirements.
- A different drug given after the first drug finishes through the same IV access: Use +96367 for a qualifying sequential infusion lasting up to one hour.
- A different drug given at the same time through the same IV access: Use +96368 for a qualifying concurrent infusion. This code is generally reported once per encounter.
What Is Included and What Is Billed Separately?
CPT 96365 includes starting the IV, using the catheter, standard tubing and syringes, flushing the IV, using saline to deliver the drug, and routine monitoring. These services are not billed separately. The medication is billed separately using its appropriate HCPCS code because 96365 covers only the work of giving the infusion.
Does Insurance Cover CPT 96365?
Medicare covers CPT 96365 when the infusion is medically necessary and meets coding and supervision rules. Many Medicaid and commercial plans also cover it when the service is properly documented. Some plans require prior authorization for the drug or treatment location.
Denials mostly happen because of missing documentation, incorrect infusion times, or errors in add-on codes. But proper documentation and correct coding can help reduce these claim denials.
CPT 99360 Explained: Standby Service
Official Definition
CPT 99360 covers standby services that require extended attendance and is reported for every 30 minutes. Some examples include standby for surgery, frozen section testing, high-risk cesarean delivery or EEG monitoring. Some older references use the term physician standby service.
When to Use CPT 99360
Standby means being ready to help when needed, rather than providing direct patient care. Some common examples include:
- A neonatologist or pediatrician standing by for a high-risk delivery.
- A surgeon or pathologist waiting for a frozen section.
- A physician standing by for surgery or EEG monitoring at another physician’s request.
Requirements for Reporting CPT 99360
- Another physician must request the standby service. Both physicians should document the reason.
- The service involves standby time without direct patient contact. If the clinician provides face-to-face care then another accurate code applies.
- The clinician must be dedicated to the standby service. They cannot care for other patients during that time.
- The standby must last at least 30 minutes. Time under 30 minutes is not reported.
- Each unit requires another full 30 minutes. Partial time does not count as a full unit.
- If the clinician performs a service then bill for the actual service. Do not report standby time for the same work.
What Many Guides Miss About CPT 99360
CPT 99360 is not for routine on-call duties or simply being available at home or in a hospital unit. The medical record must include the requesting physician, the reason for standby and the time spent waiting. Standby time and direct patient care can be billed separately when allowed but the time must be recorded separately without counting the same minutes twice. If another CPT code better describes the service provided then use that code instead of 99360.
CPT 99366: Medical Team Conference With Patient Present
Official Definition
CPT 99366 covers a medical team conference lasting at least 30 minutes with the patient and/or family present. The conference must involve an interdisciplinary healthcare team and participation by a qualified nonphysician healthcare professional.
Requirements for CPT 99366
- At least three healthcare professionals: Participants must represent different specialties or disciplines and provide direct patient care.
- Active participation: Team members must help develop, update, coordinate or implement the patient’s care plan.
- Patient or family present: The patient or a family member must attend the conference.
- At least 30 minutes: Shorter conferences do not qualify.
- Prior face-to-face care: The reporting professional must have evaluated or treated the patient face-to-face within the previous 60 days. Verify the current CPT guidelines.
- One reporter per specialty: Payer rules limit reporting to one professional from each specialty for the same conference.
- Nonphysician reporting: CPT 99366 is intended for qualified nonphysician healthcare professionals. Physicians use other applicable coding options.
How to Count Conference Time
Count the time spent conducting the clinical conference from the start of the case discussion until it ends. Do not include documentation or report-writing time. Also avoid counting the same minutes toward another time-based service.
What Many Guides Miss About CPT 99366
CPT 99366 is for nonphysician professionals so physicians cannot bill this code for their participation. Routine staff meetings, rehabilitation rounds and training sessions do not qualify. The conference must include professionals from at least three different disciplines and focus on the patient’s care and treatment plan, not administrative matters. The medical record should clearly document the conference’s start and end times to support the claim and help prevent audit issues.
Required Documentation Checklist
- Date and time: Record the start time, stop time and total conference minutes.
- Participants: List each attendee’s name, credentials and discipline.
- Patient/family attendance: Document who attended and whether they were present for the entire conference.
- Clinical content: Record the patient’s current status, risks, barriers and care goals discussed.
- Input from each discipline: Include assessments, recommendations and concerns raised by team members.
- Decisions and care plan: Document orders, referrals, therapy changes, follow-up dates and assigned responsibilities.
- Reporting clinician’s role: Explain why the clinician participated and what they contributed.
- Attestation: Include the signature and date of each reporting clinician.
99366 vs 99367 vs 99368
| Code | Patient/family present? | Who reports | Time |
| 99366 | Yes (face-to-face) | Nonphysician QHP | 30+ minutes |
| 99367 | No | Physician | 30+ minutes |
| 99368 | No | Nonphysician QHP | 30+ minutes |
How to choose in 10 seconds: Ask two questions: Was the patient or family present? Is the clinician a physician?
If the patient or family was present and the clinician is a nonphysician, use 99366. If they were absent and the clinician is a physician, use 99367. If they were absent and the clinician is a nonphysician, use 99368.
Medicare, Medicaid, and Commercial Coverage
Medicare, Medicaid, and commercial insurance plans cover CPT 96365 when the infusion is medically necessary and properly documented but drug and treatment location authorization rules vary. CPT 99360 is not covered by Medicare and is not covered by other insurers. CPT 99366 is usually bundled with other services under Medicare and does not receive separate payment. Medicaid and commercial coverage for 99366 varies by state, plan, and care program.
Modifiers and Claim Submission Tips
- GY: Use for services Medicare does not cover when a denial is needed for secondary insurance.
- 95 or payer-specific telehealth modifier: Use only if the insurance company allows the service through live video calls.
- 25: Use when a separate E/M service is provided on the same day. Do not add it to the conference code.
- 59 / X modifiers: These are rarely needed. Do not use them to avoid coding rules or missing documentation.
Reimbursable Alternatives When These Codes Are Denied
If insurance does not cover CPT 96365, 99360 or 99366 then check whether the service qualifies for another code. Some other options include chronic care management, principal care management, psychiatric collaborative care, interprofessional consultations, transitional care management, prolonged services, or telehealth and remote monitoring codes. Coverage depends on the service and the insurance company’s rules. Each code has its own requirements for time and documentation. So always use the code that correctly matches the service provided, not just to get payment.
