Can a GP refer a patient under a CCMP for the same condition they previously referred the same patient for under a MHTP?

Can a GP refer a patient under a CCMP for the same condition they previously referred the same patient for under a MHTP? Some are saying it cannot be used to 'top up' a MHTP when the patient has used all 10 sessions in a calendar year. I have emailed AskMBS but their response is vague, as usual. Some GPs are happy to refer under a CCMP after their patient has exhausted the MHTP, others are not. Any clarity you can provide would be welcome
