Wiki Cpt 31588 & 31640 - I wanted to get some clarification

[braja002@yahoo.com]

I wanted to get some clarification on these two procedures codes.

1. These procedures were done on 10-9-12 -and CPT 31588 was billed (Which has a 90 day global period)
Laryngoplasty with anterior and posterior costochondral grafting
Cervical tracheoplasty with costochondral grafting
Harvest of rib graft
Microlaryngoscopy
Bronchoscopy
Exam of ears under anesthesia
The doctor had mentioned in the notes to return to the OR for repeat MLB and open stent removal in 3 weeks

2. The patient comes back on 11/27-12 and has the following procedure
Microlaryngoscopy with excision of granulation
Bronchoscopy with dilation

CPT 31640 was billed and it got denied because it falls under 90 day global period

Can i code 31640-78 for the above procedures?

Prompt answer is appreciated

That should be fine coding it with the -78 modifier.
