First differs from A073021 at a(12).
EXAMPLE
a(5) = 11 because 11 is the smallest number greater than or equal to a(3) + a(4) = 5 + 3 = 8 which is coprime to all previous terms of the sequence.
MATHEMATICA
a[0] = a[1] = 1; a[n_] := a[n] = Module[{k = a[n - 1] + a[n - 2]}, While[! AllTrue[Range[2, n - 1], CoprimeQ[a[#], k] &], k++]; k]; Array[a, 40, 0] (* Amiram Eldar, Jun 20 2021 *)
