If the certificate is expiring in a year then also deduction can be claimed in that year but should be renewed to continue deduction in next financial years.
Such certificate is not required to furnish with return of income, but to be submitted to Assessing officer only if demanded by him.

A Civil Surgeon or Chief Medical Officer (CMO) of a government hospital.
