Conjecture: every prime occurs in A083016, so k always exists.

Robert Israel, Table of n, a(n) for n = 1..10000

a(3) = 7 because A083016(7) = 5 = prime(3).

# using program in A083016 to produce A[1]...A[m]

for i from 1 to m do B[A[i]]:= i od:

seq(B[ithprime(i)], i=1..numtheory:-pi(A[m]));

Cf. A083016.
