S62.234A (Other nondisplaced fracture of base of first metacarpal bone, right hand, initial encounter for closed fracture) compared with S62.234S (Other nondisplaced fracture of base of first metacarpal bone, right hand, sequela), from the official CMS tabular data. S62.234A and S62.234S 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.
