S29.022A vs S29.022S

S29.022A (Laceration of muscle and tendon of back wall of thorax, initial encounter) compared with S29.022S (Laceration of muscle and tendon of back wall of thorax, sequela), from the official CMS tabular data. S29.022A and S29.022S code the same injury at a different phase of treatment.

Can these codes be reported together?

Same injury, other encounter phase. S29.022A and S29.022S 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.
