S25.21XA vs S25.21XD
S25.21XA (Minor laceration of superior vena cava, initial encounter) compared with S25.21XD (Minor laceration of superior vena cava, subsequent encounter), from the official CMS tabular data. S25.21XA and S25.21XD code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S25.21XA and S25.21XD 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.
