you'd be looking at HCPC's codes - Special Transportation codes... A0xxx area - I "thought" the mileage codes started with a "Y" - but apparently, they fall under the A0xxx codes as well.
however, the transportation company is the one that bills for those services -not the medical facility, or patient, or doctor.....
lol.. been so long - the mileage code for Special Transportation that I recall were the S0xxx codes (not with a Y - I just knew it wasn't an A0xxx code)
still - the transportation company codes/bills for these services....
