The appropriate revenue codes for reporting outpatient rehabilitation services are
0420 - Physical Therapy Services
0430 - Occupational Therapy Services
0440 – Speech-language pathology services
The general classification of revenue codes is all that is needed for billing. If, however,
providers choose to use more specific revenue code classifications, the FI should accept them.
Reporting of services is not limited to specific revenue codes; e.g., services other than therapy
may be included on the same claim.
Many therapy services may be provided by both physical and occupational therapists. Other
services may be delivered by either occupational therapists or speech-language pathologists.
Therefore, providers report outpatient rehabilitation HCPCS codes in conjunction with the
appropriate outpatient rehabilitation revenue code based on the type of therapist who delivered
the service, or, if a therapist does not deliver the service, then on the type of therapy under the
plan of care (POC) for which the service is delivered.
Line Item Date of Service Reporting
Providers are required to report line item dates of service per revenue code line for outpatient
rehabilitation services. CORFs are also required to report their full range of CORF services by
line item date of service. This means each service (revenue code) provided must be repeated on
a separate line item along with the specific date the service was provided for every occurrence.
Contractors will return claims that span two or more dates if a line item date of service is not
entered for each HCPCS reported. Line item date of service reporting became effective for
claims with dates of service on or after October 1, 1998
Services that do not require line item date of service reporting may be reported before or after
those services that require line item reporting.
