S25.91XA vs S25.91XS
S25.91XA (Laceration of unspecified blood vessel of thorax, initial encounter) compared with S25.91XS (Laceration of unspecified blood vessel of thorax, sequela), from the official CMS tabular data. S25.91XA and S25.91XS code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S25.91XA and S25.91XS 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.
