S63.502A vs S63.502D
S63.502A (Unspecified sprain of left wrist, initial encounter) compared with S63.502D (Unspecified sprain of left wrist, subsequent encounter), from the official CMS tabular data. S63.502A and S63.502D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S63.502A and S63.502D 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.
