Wiki Billing 99152 and 99153 with colonoscopies

[BrendaAS]

When we bill out 99152 and 99153 the biller puts the 99153 on a facility claim (UB-40) and the procedure code (example: 45380) and 99152 on a HCFA 1500 claim. the 99153 always gets denied because it's an add on code and the insurance is looking for the initial code (99152). How are you guys billing this scenario to get the 99153 paid.

Please do not respond with the definitions of these codes and/or documentation guidelines - I've got that covered. If you have links with info, please share.
