Here's what CPT assistant has to say, but this does not qualify for multiple lobes, just bilateral.

Question
My physician performed a flexible bronchoscopy with bilateral bronchial alveolar lavage (code 31624). Should modifier -50, Bilateral procedure,be appended to code 31624, or is 31624 an inherently bilateral procedure code?
AMA Comment
From a coding perspective, the series of codes 31623 through 31656 describe unilateral procedures. To indicate that a procedure from this series was performed bilaterally, modifier -50, Bilateral procedure, should be appended to the appropriate code. Therefore, modifier -50 should be appended to code 31624 when bronchial alveolar lavage is performed bilaterally. Please note that code 31622, Bronchoscopy (rigid or flexible), diagnostic; with or without cell washing (separate procedure),is inherently bilateral, so it would not be appropriate to append modifier -50 to code 31622.
