Proof of helplessness is provided with the severely disabled person's pass, in which the mark "H" is entered. The notice from the pension office, on which the corresponding exemptions are noted, can also serve as proof. The mark 'H' corresponds to care level 4 or 5 (from 2017).

Tip: The increased disability allowance is independent of the degree of disability and can therefore also be granted for a degree of disability of less than 50.

In 2017, the mark "TBl" (deafblind) was newly introduced in social law to clarify equality with the mark "Bl". The extension is declaratory because people with the mark "Bl" and/or the mark "TBl" always also receive the mark "H".
