S35.329A vs S35.329D
S35.329A (Unspecified injury of splenic vein, initial encounter) compared with S35.329D (Unspecified injury of splenic vein, subsequent encounter), from the official CMS tabular data. S35.329A and S35.329D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S35.329A and S35.329D 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.
