The pulmonologist in a multispecialty group refers a patient to the otolaryngologist in the same group, same tax id, because he thinks that the shortness of breath that the patient is experiencing may be due to sinusitis and laryngopharyngeal reflux (lpr). the otolaryngologist decides to perform a rigid bilateral nasal endoscopy to get a better look at what is going on in the sinuses and a flexible laryngoscopy to determine if (lpr) is contributing to the problems because he could not get adequate visualization on manual exam. first the bilateral nasal endoscopy is performed and the otolaryngologist diagnosis chronic pansinusitis. next a flexible fiberoptic laryngoscope is introduced nasally and the larynx and trachea are inspected. the diagnosis is chronic laryngitis/tracheitis and lpr. he prescribes singulair and nexium and proposes endoscopic surgery will be considered in the future if the current treatment does not fully take care of the problems experienced by the patient. what cpt® and icd-10-cm codes are reported for the procedure?
