The 49-year-old, who plays Kevin Webster in the ITV soap, was temporarily written out of the show so he could seek help after he admitted taking cocaine.
And despite still being paid his £9,000-a-month salary, he won't have to pay for his treatment because 'Corrie' bosses want him back on the cobbles once he's clean.
A source told The Mirror: “ITV recognises that Michael needs help and are doing all they can for him.
“He is picking up his basic salary, just as he did during his legal fight last year, and they have also agreed to pay his fees at the clinic.
"They are very keen for him to get fit and well, and back to the show.”
Michael has faced personal troubles since exiting the soap in 2013 when he faced sex abuse allegations.
After being cleared of all charges in court, the actor returned to the cobbles, however his comeback - which is currently being shown on the ITV soap - was short lived and after six weeks on set, Michael left to address his personal issues.
The actor reportedly has the full support of his ‘Corrie’ co-stars.
“Colleagues are delighted he’s made this very difficult decision and are happy he’s now out of harm’s way,” a source told The Sunday Mirror last month. “It’s a long journey – but he’s determined to get his life back on track.”
Michael has previously insisted that he would address his problems alone, telling The Sun: “I got myself through the court case by staying strong. I can sort this out on my own too.”
