S15.211A (Minor laceration of right external jugular vein, initial encounter) compared with S15.211D (Minor laceration of right external jugular vein, subsequent encounter), from the official CMS tabular data. S15.211A and S15.211D 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.
