Latest Clinic News:
ATTN: BYRENS PATIENTS WITH MERIDIAN HEALTH PLAN AND MOLINA HEALTHCARE - Beginning October 15th, patients who currently have Meridian Health Plan and Molina Health Care (both Medicaid plans) need to sign up for a different managed care plan because those plans will not be accepted at any hospital in Calhoun County beginning January 1, 2024. Patients need to call Michigan Enrolls @ (800)975-7630. Our office is recommending Priority Health Medicaid or United Healthcare Community Plan. Patients need to be told to BE SURE they sign up letting the Managed Care plan know that Dr. Byrens is their PCP and they are established patients here because we are listed as not accepting NEW patients under both plans. If you need any assistance with the process, please contact the office at (269)781-2111 X 3.
