Nice try but...
First of all, before you can get a massage session, legit or otherwise paid through your MSP, you have to have your doctor refer you to a Licensed Massage Therapist (LMTs). So you're caught between a rock and a hard place. Even if you could convince your doctor to refer you to a Massage Parlour, MSP will only pay licensed therapists that meet its strictly defined criteria, and who are on their list of authorized payees. Further to that, LMTs typically charge fees that are significantly lower than Massage Providers, and follow invoicing guidelines for scheduled and recognized services; not BBBJs, FS, CIMs, Duos, HJs, and other services you are trying to avoid paying in the first place.
Hope that helps!
