S14.103A (Unspecified injury at C3 level of cervical spinal cord, initial encounter) compared with S14.103S (Unspecified injury at C3 level of cervical spinal cord, sequela), from the official CMS tabular data. S14.103A and S14.103S code the same injury at a different phase of treatment.
Same underlying diagnosis, different encounter phase.
The 7th character records the phase of care for the encounter being coded, so a single encounter takes one of these characters, not several. Review whether both phases belong on the same episode of care.

Same injury, other encounter phase. S14.103A and S14.103S code the same injury at a different phase of treatment, set by the 7th character.
The 7th character records the type of care given at the encounter being coded (ICD-10-CM Official Guidelines, Section I.C.19.a), so one encounter takes one of these, not both.
