S31.802A vs S31.802S
S31.802A (Laceration with foreign body of unspecified buttock, initial encounter) compared with S31.802S (Laceration with foreign body of unspecified buttock, sequela), from the official CMS tabular data. S31.802A and S31.802S code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S31.802A and S31.802S 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.
