8 units per diem – the Workers Compensation Board has spoken

First, I must give a hat tip to an unnamed source at DFS who (1) Reads my blog; (2) Listens to me lament about certain court decisions; and (3) Has been very helpful about addressing the no-fault issues that I feel are unjust.  Since this person probably does not want his/her name published, I will decline to do same.

This comes from Arbitrator Gewurz in the case of  21st Physical v. Geico (17-16-1037-6496)

To summarize:  the 8 PT units can be split between specialties – but never more than 8 per day.  CMT codes do not count to a non-chiro’s 8 unit allowance.

“Recently, however, the NYS Workers’ Compensation Board clarified the “8 unit rule.” In email correspondence from Heather MacMaster, Deputy General Counsel for the NYS Workers’ Compensation Board, to Chris Maloney at the Department of Financial Services, dated 01/30/18, it was explained that “he 8 RVU limitation is per patient per day regardless of how many body parts are treated or how many practitioners treat. The only exception is with chiro and PT. If a chiro renders manipulation only (98940-98943) and does not bill any of the other physical medicine codes, the injured worker could receive chiro and PT on the same day. This scenario is usually performed by a chiro who is affiliated with the Chiropractic Council. They only perform manipulation. The physical medicine codes that are impacted by the 8 RVU limitation are in the chiro physical medicine fee schedule but the codes for spinal manipulation are not in the general physical medicine fee schedule.”

The WCB guidance is mostly consistent with this Arbitrator’s prior interpretation. Eight units are eight units unless treatment is rendered by a medical doctor/physical therapist/occupational therapist and chiropractor on the same day. In that circumstance, the chiropractor may be reimbursed a maximum of 8 units of spinal manipulation (CPT codes 98940-98943) even when a medical doctor/physical therapist/occupational therapist has already been reimbursed 8 units.  Here, the Respondent received claims from Hills Chiropractic PC for the same dates of service as the Applicant. Hills submitted claims for reimbursement of three CPT codes: 98940, 97112, and 97140. Per date of service, the Respondent reimbursed Hills for 8 units and said units were directed towards CPT codes 98940 and 97140. Code 98940 was reimbursed in full and received 4.57 units while 97140 was partially reimbursed and received 3.43. No reimbursement was provided for CPT code 97112. The balances were denied based on the “8 unit rule.” Thereafter, the Respondent partially reimbursed the Applicant for its billed-for physical medicine modalities rendered on the same dates of service and denied the balances for the same reason as the balance of 8 units was paid to Hills. A total of 4.57 relative value units for self-employed physical therapists were reimbursed per date of service. Under the WCB’s recent guidance, the Respondent engaged in a legally valid distribution of 8 units of physical medicine modalities excluding chiropractic spinal manipulation between the two providers.”
