Hello,

I've been reviewing Medicare guidelines for chiropractic services and I'm starting to question myself on how I'm coding services for cpt codes 98943, 97110 and 97140. Our chiropractor doesn't have patient's sign an ABN so I've been adding modifier GY to the fore mentioned codes, is that correct or shouldn't I be appending any modifier even though those services are considered noncovered.

Modifier GY is used when “noncovered” services such as X-rays, massage, ultrasound and physical therapy are performed by a chiropractor and the provider elects to bill those services to Medicare. Claims billed with this modifier will be automatically denied by the Medicare claims processing system and the beneficiary will be liable for all charges, whether personally or through other insurance. Providers are required to bill “noncovered” services to Medicare when requested by the beneficiary.
 
Look at modifier AT. This is used for active treatment for CPT codes 98940,98941, 98942. These codes are payable by Medicare. GY modifier is for service not covered. Not sure what CPT codes you are using. Hope this helps
