Otolaryngology endoscopy

About 42975: Drug-induced sleep endoscopy

Flexible endoscopy during medication-induced sleep shows patterns of upper-airway collapse in patients being evaluated for obstructive sleep apnea treatment.

An otolaryngologist passes a flexible endoscope through the nose while medication-induced sleep allows assessment of how the upper airway behaves in a sleep-like state. The examination can show collapse involving structures such as the soft palate, pharyngeal walls, tongue base, or epiglottis. It is used in evaluating obstructive sleep apnea, including when airway surgery or hypoglossal nerve stimulation is being considered and the pattern of obstruction may guide treatment planning.

Report 42975 for the medication-induced, flexible endoscopic airway evaluation—not an awake office examination alone. Documentation should support the sleep-like state, the endoscopic findings, and the clinical reason for evaluating airway collapse. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, endoscopy family pricing applies. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.

42975 billing questions

How is 42975 different from an awake flexible laryngoscopy?

42975 evaluates airway behavior during medication-induced sleep. An awake flexible laryngoscopy examines the airway while the patient is awake and does not show the same sleep-related collapse pattern.

Can an awake laryngoscopy be separately reported at the same encounter?

Do not report an additional scope service solely for the flexible endoscopic examination inherent in 42975. If another endoscopic service is performed, CMS endoscopy family pricing applies when the procedures are related and performed together.

Should modifier 50 be appended for both sides of the airway?

No. CMS identifies bilateral adjustment as inappropriate for this code; the descriptor or anatomy does not support modifier 50.

Is an assistant surgeon payable?

No. CMS lists a statutory restriction on assistant-at-surgery payment for 42975; co-surgeons and team surgery are also not permitted.

What documentation supports reporting 42975?

Document the clinical reason for assessing sleep-related airway obstruction, the medication-induced sleep-like state, the flexible endoscopic examination, and the observed airway findings.
