Pulmonary endoscopy
About 31628: Transbronchial lung biopsy, one lobe
Report this bronchoscopy when transbronchial lung tissue is sampled from one lobe; use the companion add-on code for each additional lobe.
A pulmonologist or interventional pulmonologist passes a bronchoscope into the airways and obtains lung tissue through the bronchial wall, typically with biopsy forceps. The code represents sampling from one lobe during a diagnostic evaluation, such as investigating diffuse lung disease, infection, or a suspected pulmonary lesion. The procedure is commonly performed in a hospital or ambulatory surgery setting; imaging guidance may be used.
Choose this code based on the transbronchial biopsy method and one lobe sampled, not the number of tissue fragments. Record the biopsy technique, sampled lobe, and findings; report 31632 for each additional lobe sampled in the same session. When related endoscopies are performed together, CMS applies endoscopy family pricing. The 0-day global period includes same-day preoperative and postoperative care. Bilateral adjustment is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.

31628 billing questions
How is this different from 31625?
31628 is for tissue sampled from lung parenchyma through the bronchial wall. Code 31625 describes biopsy of an endobronchial site, such as visible airway mucosa or a lesion within the bronchus.
Does the number of biopsy fragments change the code?
No. This code covers transbronchial lung biopsy in one lobe, regardless of the number of tissue fragments obtained. Use 31632 for each additional lobe sampled.
Can diagnostic bronchoscopy be reported separately?
The inspection needed to perform the biopsy is part of the bronchoscopy service. Do not separately report a diagnostic bronchoscopy for that same inspection during the biopsy session.
Should modifier 50 be used for biopsies in both lungs?
No. CMS identifies bilateral adjustment as inappropriate for this code. Report the service according to the lobes sampled, including the additional-lobe add-on when applicable.
What documentation supports reporting 31628 with 31632?
Document the transbronchial biopsy method and identify each lobe sampled. The record should support one lobe for 31628 and each additional lobe reported with 31632.
How does Medicare price this with another related endoscopy?
CMS applies endoscopy family pricing when related endoscopies are performed together. The 0-day global period includes same-day preoperative and postoperative care.
