S28.212A vs S28.212D

S28.212A (Complete traumatic amputation of left breast, initial encounter) compared with S28.212D (Complete traumatic amputation of left breast, subsequent encounter), from the official CMS tabular data. S28.212A and S28.212D code the same injury at a different phase of treatment.

Can these codes be reported together?

Same injury, other encounter phase. S28.212A and S28.212D 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.
