T60.93XA (Toxic effect of unspecified pesticide, assault, initial encounter) compared with T60.93XD (Toxic effect of unspecified pesticide, assault, subsequent encounter), from the official CMS tabular data. T60.93XA and T60.93XD 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.

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.
