Clinical Indicators: Diagnostic Nasal Endoscopy
Approach ProcedureCPTRBRVS Global Days
Nasal endoscopy, diagnostic, unilateral or bilateral (separate procedure)*31231 000
*Note: Separate Procedure by CPT definition means the code should not be reported with other procedures of which it is a part; in this case, therapeutic nasal/sinus endoscopic procedures.
  1. History (one or more required)
    1. Obstructed nasal breathing
    2. Epistaxis, anterior or posterior, either active or past history
    3. Facial pain or headache consistent with sinonasal origin
    4. Persistant nasal drainage (anterior or posterior) of more than
    5. 10 day duration or when an endoscopic-directed culture is desired (severe symptoms, immunocompromise, suspected suppurative complication of rhinosinusitis, failure to respond to treatment, etc)
    6. Sinus barotrauma (after flying or diving)
    7. External nasal trauma to rule out septal hematoma
    8. Watery rhinorrhea suggestive of cerebrospinal fluid leak
    9. Persistent sinus abnormality on diagnostic imaging study
    10. History suggestive of nasal foreign body or mass
    11. Follow-up examination of known nasal, sinus, or nasopharyngeal neoplasm
    12. Anosmia or hyposmia
    13. Follow-up examination following endoscopic sinus surgery
    14. Snoring and/or sleep apnea
    15. Oro -antral (oro-maxillary) fistula
    16. Assess for interval response to medical therapy in patients with chronic and recurrent acute sinusitis
    17. Monitor for recurrence of nasal polyps
  2. Physical Examination (one required)
    1. Anterior rhinoscopy insufficient to account for symptoms.
    2. Abnormal anterior rhinoscopy requiring more thorough nasal evaluation, including, but not limited to suspected chronic rhinosinusitis, sinonasal polyposis, neoplasm, and/or foreign body

Post-Procedure Observations

  1. Nasal bleeding.
  2. New nasal or facial pain.

Outcome Review

  1. Document procedure, including pertinent anatomic sites with relevant findings of areas described in introduction language of endoscopy section of the CPT book, and any complications on the day of procedure.

Patient Information

Nasal endoscopy is done when there may be a condition or disease in the nose or sinuses that is not adequately visualized on routine examination. The nose may be sprayed with a decongestant and topical anesthetic before insertion of a rigid and/or flexible endoscope. The procedure can be performed on both adults and children, although the latter may require general anesthesia. The throat may be numb for several minutes following use of an anesthetic.
