Wiki Incision / amputation

[sledson]

I billed a 2000 for dos 1-4-10 (done in the office)
to medicare (west virginia)

and then billed a 28805 dos 1-5-10 (outpatient hospital)
with a 79 modifier

the 28805 denied for procedure/bill type is inconsistent
with the place of service

anyone have any idea why it denied?

Thanks for your help.
