S41.022A (Laceration with foreign body of left shoulder, initial encounter) compared with S41.022D (Laceration with foreign body of left shoulder, subsequent encounter), from the official CMS tabular data. S41.022A and S41.022D 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.
