S52.282A (Bent bone of left ulna, initial encounter for closed fracture) compared with S52.282D (Bent bone of left ulna, subsequent encounter for closed fracture with routine healing), from the official CMS tabular data. S52.282A and S52.282D 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.
