For constants:
 ld a,l      ; 4
 add a,N     ; 7       N is the constant
 ld l,a      ; 4
 jp nc,skip  ; 10 or 1
 inc h       ; 4
skip:        ; = 20 or 29

For A:
 add a,l     ; 4
 ld l,a      ; 4
 jp nc,skip  ; 10 or 1
 inc h       ; 4
skip:        ; = 13 or 22

If you can trash DE (or BE):
 ld d,0      ; 7
 ld e,a      ; 4 (or 7, if you load it with N)
 add hl,de   ; 11
             ; = 22 for A, 25 for constants
