S28.229A vs S28.229S
S28.229A (Partial traumatic amputation of unspecified breast, initial encounter) compared with S28.229S (Partial traumatic amputation of unspecified breast, sequela), from the official CMS tabular data. S28.229A and S28.229S code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S28.229A and S28.229S 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.
