What that number is
When the injury case is closed, an INAIL doctor writes a percentage. It says how much the injury has reduced your body, according to a table that is the same for everyone.
It does not measure pain. It does not measure how hard it is to go back to the job you had. It is one doctor's opinion: two doctors, looking at the same knee, can write two different numbers.
Why that number matters
Because it decides what you get.
One point more or less changes everything. That is why an assessment at 15% should always be read again carefully.
If you disagree, you appeal
You have sixty days from the day you receive INAIL's letter. Within that time an appeal to INAIL is filed: it explains why that percentage is wrong, states the correct one and attaches a medical-legal certificate supporting it.
INAIL has sixty days to answer. If it says no, or does not answer, the case goes before the labour court: there the assessment is done again by a doctor appointed by the judge, not by INAIL.
And INAIL does not pay for everything
INAIL pays according to its own tables. The harm you suffered may be greater: the part INAIL does not cover, the suffering, what the table does not count.
You do not ask INAIL for that difference. You ask the employer, if the accident happened because safety rules were not respected, or whoever caused the accident. They are two different routes and they are taken together.
Were you given a percentage you don't agree with?
