T53.6X1A vs T53.6X1S
T53.6X1A (Toxic effect of other halogen derivatives of aliphatic hydrocarbons, accidental (unintentional), initial encounter) compared with T53.6X1S (Toxic effect of other halogen derivatives of aliphatic hydrocarbons, accidental (unintentional), sequela), from the official CMS tabular data. T53.6X1A and T53.6X1S code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. T53.6X1A and T53.6X1S 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.
