CPT 92512 describes the diagnostic test used to evaluate the respiratory function of the nose by measuring airflow and air pressure. This article will cover the description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, similar codes and billing examples.
1. What is CPT Code 92512?
CPT 92512 can be used to describe a diagnostic test that assesses and measures nasal airflow and pressures. This test, known as rhinomanometry, helps the provider evaluate the respiratory function of the nose. By measuring the airflow during inhalation and exhalation, as well as the air pressure in the nose, the provider can diagnose any anatomical or mucosal abnormalities that may be present.
2. Official Description
The official description of CPT code 92512 is: ‘Nasal function studies (e.g., rhinomanometry).’ This code encompasses the diagnostic test used to evaluate nasal airflow and pressures, providing valuable information about the respiratory function of the nose.
- The provider begins the procedure by having the patient sit upright.
- The patient is instructed to blow their nose to clear any obstructions.
- A pressure sensing probe is then inserted into one nostril.
- The patient wears a facemask tightly over their face, which is connected to a rhinomanometer.
- The provider takes measurements of airflow and pressure in each nostril.
- The patient inhales a nasal decongestant, and the measurements are repeated.
- A difference in resistance between the two measurements may indicate nasal mucosal congestion or obstruction.
4. Qualifying circumstances
CPT 92512 is used when a provider needs to assess and measure nasal airflow and pressures to diagnose any abnormalities or obstructions in the respiratory function of the nose. This test is typically performed when there is a suspicion of anatomical or mucosal abnormalities that may be affecting the patient’s ability to breathe through their nose.
5. When to use CPT code 92512
CPT code 92512 should be used when a provider performs a nasal function study, specifically rhinomanometry, to evaluate nasal airflow and pressures. This code is appropriate when there is a need to assess the respiratory function of the nose and diagnose any abnormalities or obstructions that may be present.
6. Documentation requirements
To support a claim for CPT 92512, the provider must document the following information:
- Reason for performing the nasal function study
- Details of the procedure, including the use of a pressure sensing probe and a rhinomanometer
- Date and time of the procedure
- Measurement results of airflow and pressure in each nostril
- Any observations or findings indicating anatomical or mucosal abnormalities
- Signature of the provider performing the procedure
7. Billing guidelines
When billing for CPT 92512, ensure that the procedure performed is a nasal function study, specifically rhinomanometry. This code should be reported separately and should not be reported with other codes unless there are additional services provided that are distinct and separate from the nasal function study.
8. Historical information
CPT 92512 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.
- A provider performs a nasal function study using rhinomanometry to assess a patient’s nasal airflow and pressures to diagnose a deviated septum.
- A patient presents with chronic nasal congestion, and a provider performs a nasal function study to evaluate the respiratory function of the nose and identify any obstructions.
- A provider uses rhinomanometry to assess a patient’s nasal airflow and pressures before and after the administration of a nasal decongestant to determine the effectiveness of the medication.
- A patient complains of difficulty breathing through their nose, and a provider performs a nasal function study to evaluate the respiratory function and identify any anatomical abnormalities.
- A provider performs a nasal function study using rhinomanometry to assess a patient’s nasal airflow and pressures as part of a pre-operative evaluation for sinus surgery.
