How To Use CPT Code 94662

CPT 94662 describes the initiation and management of continuous negative pressure ventilation (CNP) in patients who are unable to breathe on their own due to paralysis or other pathologies. This article will provide an overview of CPT 94662, including its official description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, similar codes, and examples.

1. What is CPT Code 94662?

CPT 94662 is used to describe the initiation and management of continuous negative pressure ventilation (CNP) in patients who are unable to breathe on their own. This code is specifically used when a provider utilizes a negative pressure full body respirator, known as an airtight cuirass, to apply subatmospheric pressure to the chest wall. By doing so, the lungs expand and air is drawn into them, assisting the patient in breathing.

2. Official Description

The official description of CPT code 94662 is: ‘Continuous negative pressure ventilation (CNP), initiation and management.’

3. Procedure

1. The provider initiates continuous negative pressure ventilation using an airtight cuirass, which is placed around the patient’s chest wall.
2. The cuirass applies subatmospheric pressure to the chest wall, expanding the lungs and drawing air into them.
3. The provider adjusts the settings of the cuirass to ensure optimal ventilation for the patient.
4. The provider manages the continuous negative pressure ventilation throughout the duration of the treatment.

4. Qualifying circumstances

CPT 94662 is used when a patient requires continuous negative pressure ventilation due to paralysis or other pathologies that prevent them from breathing on their own. The use of an airtight cuirass and the application of subatmospheric pressure to the chest wall are essential components of this procedure.

5. When to use CPT code 94662

CPT code 94662 should be used when a provider initiates and manages continuous negative pressure ventilation using an airtight cuirass. It is important to note that this code should not be reported if the provider performs other ventilation therapies or if the work is already included in an evaluation and management (E/M) code.

6. Documentation requirements

To support a claim for CPT code 94662, the provider must document the following information:

• The patient’s condition necessitating continuous negative pressure ventilation
• The use of an airtight cuirass for subatmospheric pressure application
• The date and duration of the treatment
• Any adjustments made to the cuirass settings
• Management of the continuous negative pressure ventilation throughout the procedure

7. Billing guidelines

When billing for CPT code 94662, ensure that the provider has initiated and managed continuous negative pressure ventilation using an airtight cuirass. It is important to consider whether to report the ventilation therapy separately or include it in an E/M code, depending on the documentation and focus of the encounter. If the provider primarily focuses on ventilation management, report a ventilation management code only. If the provider performs ventilation management during a larger E/M encounter, report the E/M code.

8. Historical information

CPT code 94662 was added to the Current Procedural Terminology system on January 1, 1990. There have been no updates or changes to the code since its addition.

9. Examples

1. A patient with paralysis requires continuous negative pressure ventilation using an airtight cuirass, which is initiated and managed by the provider.
2. A patient with a respiratory pathology necessitates continuous negative pressure ventilation with the assistance of an airtight cuirass, which is initiated and managed by the provider.
3. A provider applies subatmospheric pressure to the chest wall of a patient using an airtight cuirass, initiating and managing continuous negative pressure ventilation.
4. A patient unable to breathe on their own due to paralysis receives continuous negative pressure ventilation with the use of an airtight cuirass, which is initiated and managed by the provider.
5. A provider utilizes an airtight cuirass to apply subatmospheric pressure to the chest wall of a patient, initiating and managing continuous negative pressure ventilation.
6. A patient with a respiratory pathology undergoes continuous negative pressure ventilation using an airtight cuirass, which is initiated and managed by the provider.
7. A provider initiates and manages continuous negative pressure ventilation in a patient with paralysis, utilizing an airtight cuirass for subatmospheric pressure application.
8. A patient requiring assistance with breathing due to a respiratory pathology receives continuous negative pressure ventilation with the aid of an airtight cuirass, which is initiated and managed by the provider.
9. A provider applies subatmospheric pressure to the chest wall of a patient using an airtight cuirass, initiating and managing continuous negative pressure ventilation.
10. A patient unable to breathe independently due to paralysis undergoes continuous negative pressure ventilation with the use of an airtight cuirass, which is initiated and managed by the provider.
