Are you referencing the ASA position paper "REPORTING POSTOPERATIVE PAIN PROCEDURES IN CONJUNCTION WITH ANESTHESIA" that was updated last September?
http://www.asahq.org/publicationsAndServices/standards/43.pdf
Note that the transforaminal epidural injection codes (64479-64484) are not included in the list. Side note: rarely to never would transforaminal epidural injections be performed for postoperative pain control.
I have seen providers report 3 levels of transforaminal epidural injections in a multitude of methods and have most payers process them correctly, such as
64483 with 1 unit of service
64484 with 2 units of service
OR
64483 with 1 unit of service
64484 with 1 unit of service
64484 - 59 with 1 unit of service
OR
64483 with 1 unit of service
64484 with 1 unit of service
64484 - 76 with 1 unit of service
The method that is problematic with many payers is multiple line items that are identical...
64483 with 1 unit of service
64484 with 1 unit of service
64484 with 1 unit of service
The payer's claims processing software views line 2 & 3 as identical and processes the second line item as denied due to duplicate data entry. This denial can certainly be appealed but causes delays in collections and increases the work (cost) of the billing staff.
Unfortunately, with HIPAA we didn't get payer uniformity with reporting simple things like bilateral procedures and/or multiple units of add-on codes! :>) Just those 2 issues could most likely reduce the costs of health care but in my mind "He who has the gold, has the power to determine how they want services reported." In essence, payers still have control of how we need to report these types of services and there isn't necessarily one size fits all or one solution that will work with all payers. Rats, if only we had the ideal world! :>)
