S82.399A vs S82.399H
S82.399A (Other fracture of lower end of unspecified tibia, initial encounter for closed fracture) compared with S82.399H (Other fracture of lower end of unspecified tibia, subsequent encounter for open fracture type I or II with delayed healing), from the official CMS tabular data. S82.399A and S82.399H code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S82.399A and S82.399H 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.
