S35.513A vs S35.513S
S35.513A (Injury of unspecified iliac artery, initial encounter) compared with S35.513S (Injury of unspecified iliac artery, sequela), from the official CMS tabular data. S35.513A and S35.513S code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S35.513A and S35.513S 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.
