The claimant sought removal from the MIG and entitlement to psychological treatment. Adjudicator Grant concluded that the insurer failed to respond to the treatment plan within 10 days. Even though the treatment plan was denied on HCAI, no letter with the medical and other reasons for the denial was sent to the claimant until two months later. The insurer was therefore prohibited from relying upon the MIG. However, Adjudicator Grant held that the claimant failed to prove that the proposed psychological treatment was reasonable and necessary.
