MARCELO CHAN HAU vs. BARRETT BUSINESS SERVICES, INC., ACE AMERICAN INSURANCE COMPANY, CORVEL CORPORATION

The Workers' Compensation Appeals Board affirmed a prior decision denying liens for medical treatment provided by claimants Ira Reinherz Chiropractic Inc. and Sachet Pream. The Board found that the applicant received treatment within the employer's Medical Provider Network (MPN) and that there was no evidence the defendant denied medical treatment or failed to comply with MPN regulations. Therefore, the defendant was not liable for the self-procured treatment provided by the lien claimants outside the MPN. The claimants' argument regarding procedural time requirements was also rejected.
