T71.122A vs T71.122D
T71.122A (Asphyxiation due to plastic bag, intentional self-harm, initial encounter) compared with T71.122D (Asphyxiation due to plastic bag, intentional self-harm, subsequent encounter), from the official CMS tabular data. T71.122A and T71.122D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. T71.122A and T71.122D 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.
