T84.196A vs T84.196S

T84.196A (Other mechanical complication of internal fixation device of bone of right lower leg, initial encounter) compared with T84.196S (Other mechanical complication of internal fixation device of bone of right lower leg, sequela), from the official CMS tabular data. T84.196A and T84.196S code the same injury at a different phase of treatment.

T84.196A

Initial encounter

Other mechanical complication of internal fixation device of bone of right lower leg, initial encounter

↔

T84.196S

Sequela

Other mechanical complication of internal fixation device of bone of right lower leg, sequela

Same underlying diagnosis, different encounter phase.

The 7th character records the phase of care for the encounter being coded, so a single encounter takes one of these characters, not several. Review whether both phases belong on the same episode of care.

Can these codes be reported together?

Same injury, other encounter phase. T84.196A and T84.196S 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.
