T83.85XA (Stenosis due to genitourinary prosthetic devices, implants and grafts, initial encounter) compared with T83.85XS (Stenosis due to genitourinary prosthetic devices, implants and grafts, sequela), from the official CMS tabular data. T83.85XA and T83.85XS 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. T83.85XA and T83.85XS 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.
