The presumption of this subdivision is rebuttable only by evidence discovered subsequent to the 90-day period.(2) Notwithstanding paragraph (1), for injuries or illnesses defined in Sections 3212 to 3212.85, inclusive, and Sections 3212.9 to 3213.2, inclusive, if the liability is not rejected within 75 days after the date the claim form is filed pursuant to Section 5401, the injury shall be presumed compensable under this division.
