Physical Therapy and Chiropractor Providers

Physical therapy and chiropractic services must be submitted on a CMS 1500 or UB 04 form.

SIF allows up to 4 modalities/procedures to be billed per date of service, related to injury.

When billing time codes, medical documentation needs to support the time being billed for services performed. Otherwise, bills may be denied or down coded to support the documentation provided.

When treating multiple body parts for the same claim and/or injury, bill all services performed on a single day with total units per CPT code. Providers should utilize the diagnosis box 21 on CMS 1500 claim form to indicate which body part/injury is being treated.
