(1) A mental or nervous injury due to stress, fright, or excitement only is not an injury by accident arising out of the employment. Nothing in this section shall be construed to allow for the payment of benefits under this chapter for mental or nervous injuries without an accompanying physical injury requiring medical treatment. A physical injury resulting from mental or nervous injuries unaccompanied by physical trauma requiring medical treatment shall not be compensable under this chapter.

(2) Mental or nervous injuries occurring as a manifestation of an injury compensable under this chapter shall be demonstrated by clear and convincing medical evidence by a licensed psychiatrist meeting criteria established in the most recent edition of the diagnostic and statistical manual of mental disorders published by the American Psychiatric Association. The compensable physical injury must be and remain the major contributing cause of the mental or nervous condition and the compensable physical injury as determined by reasonable medical certainty must be at least 50 percent responsible for the mental or nervous condition as compared to all other contributing causes combined. Compensation is not payable for the mental, psychological, or emotional injury arising out of depression from being out of work or losing employment opportunities, resulting from a preexisting mental, psychological, or emotional condition or due to pain or other subjective complaints that cannot be substantiated by objective, relevant medical findings.

(3) Subject to the payment of permanent benefits under s. 440.15, in no event shall temporary benefits for a compensable mental or nervous injury be paid for more than 6 months after the date of maximum medical improvement for the injured employee’s physical injury or injuries, which shall be included in the period of 104 weeks as provided in s. 440.15(2) and (4). Mental or nervous injuries are compensable only in accordance with the terms of this section.
