T84.296A vs T84.296D

T84.296A (Other mechanical complication of internal fixation device of vertebrae, initial encounter) compared with T84.296D (Other mechanical complication of internal fixation device of vertebrae, subsequent encounter), from the official CMS tabular data. T84.296A and T84.296D code the same injury at a different phase of treatment.

Can these codes be reported together?

Same injury, other encounter phase. T84.296A and T84.296D 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.
