A complaint was made to the Attorney General that Ian Paterson's sentence of 15 years was too low.
Under the "undue leniency" scheme, the Attorney General's Office has 28 days to review a sentence and make a decision.
In the case of Ian Paterson, who was sentenced to 15 years in May for 17 counts of wounding with intent and three counts of wounding, a complaint was made by one of his former patients.
As a result, the case was sent to the Court of Appeal.
Today, the sentence handed down by Justice Jeremy Baker on 31st May will be reviewed.
Ian Paterson, who is currently serving his sentence at Nottingham Prison is expected to appear via videolink.
The case will be presented by the Solicitor General. The sentence could stay the same, or be increased, depending on the findings.
