What 31635 covers

A pulmonologist or thoracic surgeon uses a bronchoscope to locate and retrieve an object lodged in the trachea or a bronchus. Typical cases include an aspirated food fragment or another object obstructing the airway. The physician may use retrieval instruments through a flexible or rigid scope, with the approach guided by the object’s location and the patient’s condition. Bronchoscopic foreign body removal is commonly performed in a hospital or other facility setting.

Report 31635 when the bronchoscopic intervention removes a foreign object, and document its airway location, the retrieval performed, and the outcome. The code has 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; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

31635 billing questions

How is 31635 different from diagnostic bronchoscopy 31622?

Use 31635 when the bronchoscopy includes retrieval of a foreign object. Use 31622 when the service is diagnostic inspection rather than foreign body removal.

Can diagnostic bronchoscopy be reported with 31635?

The diagnostic inspection is part of the bronchoscopic removal service when performed as part of the same procedure. Endoscopy family pricing applies when related endoscopies are performed together.

Which modifier applies for removal from both lungs?

Modifier 50 is inappropriate for 31635. The code’s descriptor or anatomy makes a bilateral adjustment inapplicable.

Can an assistant surgeon or co-surgeon be reported?

Medicare does not pay an assistant at surgery for 31635. Co-surgeons and team surgery are not permitted for this service.

What documentation supports reporting 31635?

Document the foreign object, its location in the trachea or bronchial airway, the bronchoscopic retrieval performed, and the result.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
