Official Description

Patient/caregiver training for initiation of home international normalized ratio (INR) monitoring under the direction of a physician or other qualified health care professional, face-to-face, including use and care of the INR monitor, obtaining blood sample, instructions for reporting home INR test results, and documentation of patient's/caregiver's ability to perform testing and report results

Common Language Description

The CPT® Code 93792 refers to the process of providing patient or caregiver training for the initiation of home international normalized ratio (INR) monitoring, which is conducted under the direction of a physician or other qualified healthcare professional. This training is performed face-to-face and encompasses several critical components. It includes instruction on the use and care of the INR monitor, which is a portable device designed to measure the time it takes for blood plasma to clot. Additionally, the training covers the procedure for obtaining a blood sample, typically through a finger stick, and provides detailed instructions for reporting the results of home INR tests back to the healthcare provider. A vital aspect of this training is the documentation of the patient's or caregiver's ability to perform the testing and accurately report the results, ensuring that they are competent in managing their anticoagulation therapy at home. The INR monitoring system is particularly important for patients requiring anticoagulation therapy due to conditions such as artificial heart valves, chronic atrial fibrillation, and venous thromboembolism, as it allows for greater flexibility and minimizes the risks associated with improper anticoagulation levels.

1. Indications

The procedure described by CPT® Code 93792 is indicated for patients who require anticoagulation therapy due to specific medical conditions. These conditions include:

  • Artificial Heart Valves Patients with artificial heart valves often need regular monitoring of their blood clotting levels to prevent complications such as thrombosis.
  • Chronic Atrial Fibrillation This condition increases the risk of stroke, necessitating careful management of anticoagulation therapy to maintain appropriate blood clotting levels.
  • Venous Thromboembolism Patients with a history of venous thromboembolism require ongoing monitoring to prevent recurrence and manage their anticoagulation treatment effectively.

2. Procedure

The procedure for training patients or caregivers in home INR monitoring involves several key steps, which are detailed as follows:

  • Step 1: Face-to-Face Training The healthcare provider conducts a face-to-face training session with the patient or caregiver. This session is essential for ensuring that the individual understands the importance of INR monitoring and how to perform it correctly.
  • Step 2: Instruction on Use and Care of the INR Monitor During the training, the provider explains how to use the INR monitor, including how to set it up, operate it, and maintain it properly to ensure accurate readings.
  • Step 3: Blood Sample Collection The patient or caregiver is instructed on how to obtain a blood sample using a lancet for a finger stick. This step is crucial as it directly impacts the accuracy of the INR measurement.
  • Step 4: Reporting Results The training includes guidance on how to report the INR test results to the healthcare provider. This communication is vital for making necessary adjustments to the patient's anticoagulation therapy.
  • Step 5: Documentation of Competency Finally, the healthcare provider documents the patient's or caregiver's ability to perform the testing and report the results, ensuring that they are competent in managing their anticoagulation therapy independently.

3. Post-Procedure

After the training session, the patient or caregiver is expected to perform home INR monitoring as directed by the healthcare provider. They should regularly test their INR levels at intervals specified by the provider and report the results promptly. This ongoing communication is essential for adjusting anticoagulation medication as needed to maintain therapeutic levels and prevent complications. Additionally, the healthcare provider may schedule follow-up appointments to review the patient's INR results and make any necessary changes to the treatment plan.

25 Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
