CPT code 93720 is used for total body plethysmography, a test measuring lung volume and airway resistance to assess respiratory health.
CPT code 93720 is used to describe the procedure of total body plethysmography. This diagnostic test measures the volume of air in the lungs, including the air that remains after a full exhalation, known as residual volume. It provides comprehensive data on lung function by assessing lung volumes and airway resistance, which is crucial for diagnosing and managing respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other pulmonary disorders. This code is typically used by healthcare providers to ensure accurate billing and documentation of the procedure in the patient's medical records.
For CPT code 93720, which pertains to total body plethysmography, the following modifiers may be applicable depending on the specific circumstances of the service provided:
1. Modifier 26 - Professional Component: This modifier is used when only the professional component of the service is being billed. It indicates that the provider is billing for the interpretation of the test results, not the technical component.
2. Modifier TC - Technical Component: This modifier is used when only the technical component of the service is being billed. It indicates that the provider is billing for the use of equipment and technician services, excluding the professional interpretation.
3. Modifier 59 - Distinct Procedural Service: This modifier is used to indicate that a procedure or service was distinct or independent from other services performed on the same day. It may be necessary if multiple procedures are performed that are not typically reported together.
4. Modifier 76 - Repeat Procedure by Same Physician: This modifier is used when the same procedure is repeated by the same physician on the same day. It indicates that the procedure was necessary to be repeated for the patient's care.
5. Modifier 77 - Repeat Procedure by Another Physician: This modifier is used when the same procedure is repeated by a different physician on the same day. It indicates that the procedure was necessary to be repeated for the patient's care.
6. Modifier 91 - Repeat Clinical Diagnostic Laboratory Test: Although typically used for laboratory tests, this modifier can be applied if the test is repeated for clinical reasons on the same day to obtain subsequent results.
These modifiers should be used appropriately based on the specific circumstances of the service provided and in accordance with payer policies and guidelines. Proper use of modifiers ensures accurate billing and reimbursement for services rendered.
CPT code 93720, which pertains to total body plethysmography, is reimbursed by Medicare, but the reimbursement is subject to specific conditions and guidelines. The Medicare Physician Fee Schedule (MPFS) determines the reimbursement rates for services covered under Medicare Part B, including those associated with CPT codes. However, the actual reimbursement can vary based on geographic location and other factors, as determined by the local Medicare Administrative Contractor (MAC). Each MAC has the authority to interpret national policies and establish local coverage determinations (LCDs) that may affect whether and how a particular service, such as that represented by CPT code 93720, is reimbursed. Therefore, healthcare providers should consult their specific MAC for detailed information on coverage and reimbursement for this code.
