S60.945A (Unspecified superficial injury of left ring finger, initial encounter) compared with S60.945S (Unspecified superficial injury of left ring finger, sequela), from the official CMS tabular data. S60.945A and S60.945S code the same injury at a different phase of treatment.
Same underlying diagnosis, different encounter phase.
The 7th character records the phase of care for the encounter being coded, so a single encounter takes one of these characters, not several. Review whether both phases belong on the same episode of care.
