Wash. Admin. Code § 296-23A-0550
The department will deny interim bills which are assigned to diagnosis-related-groups (DRGs) paid per case rates by the department.
If an interim bill is coded as a diagnosis-related-group (DRG) not paid per case rates by the department, then the bill will be paid using the applicable percent of allowed charges (POAC) factor and per diem rates. If a subsequent bill coded as a DRG paid per case rates by the department, for the same injured worker, has a first date of service within seven days of the last date of service of the previous bill, then the bills will be subject to review and adjustment by the department.
