Wiki acute exacerbation of chronic bronchitis

[pmaddox]

We are having a debate here with the correct coding of Acute exacerbation of chronic bronchitis. Documentaion does not state "obstructive" so would it be unspecified 491.9 or 491.21?
Thanks

I would go with the 491.21 based on the "acute" and "exacerbation".

491.21

Will code it as 491.21
