S32.409A vs S32.409D
S32.409A (Unspecified fracture of unspecified acetabulum, initial encounter for closed fracture) compared with S32.409D (Unspecified fracture of unspecified acetabulum, subsequent encounter for fracture with routine healing), from the official CMS tabular data. S32.409A and S32.409D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S32.409A and S32.409D 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.
