Work-hardening Program
Work Hardening
Work-hardening programs help workers restore function so that they can successfully return to work.
The basics about work-hardening in Washington State
Work-hardening programs or services are:
- Made up of real or simulated work tasks, conditioning exercises, and education used to restore physical, behavioral, and vocational functions.
- Highly-structured, multi-disciplinary, and individualized for each worker.
- Delivered in a 4-week program that begins at 4 hours a day and progresses up to 8 hours 3-5 times per week.
- Delivered only by approved providers.
More detail is available under work-hardening programs standards.
Getting approval
The work-hardening program requires:
- Referral from the worker's attending provider and
- Prior authorization by the claim manager.
Extending the work-hardening program
- Program extensions beyond 4 weeks must be authorized in advance by the claim manager and are based on documentation of progress and the worker's ability to benefit from the program extension.

Forms used to bill L&I
- CMS 1500 (F245‑127‑000) - For physical therapists.

- UB04 (F245‑367‑000) - For hospitals.
Billing examples
Less than 2 hours per day
Less than 2 hours per day does not meet the work hardening program standards and must be billed outside of the work hardening program codes. Use the CPT™ code that appropriately reflects the services provided. Example of less than 2 hours per day:
The worker arrives for work hardening but is unable to fully participate that day. Services should be billed using CPT™ codes that reflect the services provided. This should be counted as an absence by the worker in determining compliance with the program.
Workers must participate a minimum of 4 hours per day, increasing to 7 to 8 hours per day by the 4th week.
Less than 1 hour of CPT™ 97546
After the first 2 hours of service on any day (CPT™ 97545), if less than 38 minutes of service is provided.
- The Procedure code CPT™ 97546 must be billed as a separate line item with a -52 modifier.
AND - The charged amount is pro-rated to reflect the reduced level of service.
Example of less than 1 hour of CPT™ 97546:
Worker completes 4 hours and 20 minutes of treatment. Billing for the date of service would include 3 lines:
| Example of service billing | |||
|---|---|---|---|
| CPT™ code | Modifier | Charged amount | Unit = Hour |
| 97545 | Usual and customary | 1 = 2 hours. | |
| 97546 | Usual and customary | 2 = 2 hours. | |
| 97546 | -52 | Usual and customary - 33% (used 20 of 60 minutes) |
1 = 20 minutes. |
| Total time billed | 4 hours, 20 minutes. | ||
Billing for services in multi-disciplinary programs
Each provider must bill for the services they are responsible for each day. Both occupational (OT) and physical therapists (PT) may bill for the same date of service.
Only one unit of CPT™ 97545 (first 2 hours) will be paid per day, per claimant. The total number of hours billed should not exceed the hours that the direct services was provided. Example of billing in multi-disciplinary programs:
On the same day, the PT is responsible for the conditioning/aerobic activity of the worker's program, which lasted 2 hours. The OT is responsible for the work simulation portion of the worker's program, which lasted 4 hours.
The 6 hours of services could be billed in 1 of 2 ways:
| Billing option 1 | ||
|---|---|---|
| Type | CPT™ code | Unit = Hours |
| PT | 97545 | 1 = 2 hours. |
| OT | 97546 | 4 = 4 hours. |
| Total time billed: | 6 hours. | |
| Billing option 2 | ||
|---|---|---|
| Type | CPT™ code | Unit = Hours |
| OT | 97545 | 1 = 2 hours. |
| OT | 97546 | 2 = 2 additional hours. |
| PT | 97546 | 2 = 2 hours. |
| Total time billed: | 6 hours. | |
Billing for additonal services
The work hardening provider can only bill for work hardening services (1001M, CPT™ 97545, 97546) per day, per claimant unless they get prior authorization from the claim manager. Documentation must support the billing of additional services. Example of billing for additional services:
A worker participates in a work hardening program for 5 hours one day. As part of the day's treatment the physical therapist provides ultrasound for 20 minutes. If the therapist did not get prior authorization and provide supportive documentation, they cannot bill code CPT™ 97035 for the ultrasound.
| Billing for additional services without prior authorization | ||
|---|---|---|
| CPT™ code | Unit = Hours | |
| 97545 | 1 = 2 hours. | |
| 97546 | 3 = 3 additional hours. | |
| Total time billed | 5 hours. | |
