S31.14AA vs S31.14AD
S31.14AA (Puncture wound of abdominal wall with foreign body, unspecified flank without penetration into peritoneal cavity, initial encounter) compared with S31.14AD (Puncture wound of abdominal wall with foreign body, unspecified flank without penetration into peritoneal cavity, subsequent encounter), from the official CMS tabular data. S31.14AA and S31.14AD code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S31.14AA and S31.14AD 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.
