Need a little help with Chiro/PT coding

Hi,

I work for a chiropractor in Maryland (where they have PT privileges). The doc suggested that for insurances that don't cover dry needling, that I can just bill that procedure as "manual therapy" (97140)

He also said he thought he heard that it was OK to do the same thing for spinal manipulations - in other words in insurance doesn't cover spinal manips (98940) that it would be OK to bill it as manual therapy (97140).

This doesn't sound right to me - I haven't come across any documentation saying that 98940 and 97140 are interchangable. Any thoughts?
