S92.055A (Nondisplaced other extraarticular fracture of left calcaneus, initial encounter for closed fracture) compared with S92.055S (Nondisplaced other extraarticular fracture of left calcaneus, sequela), from the official CMS tabular data. S92.055A and S92.055S 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.
