T47.2X4A vs T47.2X4D
T47.2X4A (Poisoning by stimulant laxatives, undetermined, initial encounter) compared with T47.2X4D (Poisoning by stimulant laxatives, undetermined, subsequent encounter), from the official CMS tabular data. T47.2X4A and T47.2X4D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. T47.2X4A and T47.2X4D 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.
