S61.308A vs S61.308S
S61.308A (Unspecified open wound of other finger with damage to nail, initial encounter) compared with S61.308S (Unspecified open wound of other finger with damage to nail, sequela), from the official CMS tabular data. S61.308A and S61.308S code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S61.308A and S61.308S 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.
