S31.110A vs S31.110S
S31.110A (Laceration without foreign body of abdominal wall, right upper quadrant without penetration into peritoneal cavity, initial encounter) compared with S31.110S (Laceration without foreign body of abdominal wall, right upper quadrant without penetration into peritoneal cavity, sequela), from the official CMS tabular data. S31.110A and S31.110S code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S31.110A and S31.110S code the same injury at a different phase of treatment, set by the 7th character.
The 7th character records the type of care given at the encounter being coded (ICD-10-CM Official Guidelines, Section I.C.19.a), so one encounter takes one of these, not both.
