S35.404A vs S35.404S
S35.404A (Unspecified injury of right renal vein, initial encounter) compared with S35.404S (Unspecified injury of right renal vein, sequela), from the official CMS tabular data. S35.404A and S35.404S code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S35.404A and S35.404S 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.
