T65.811A vs T65.811S
T65.811A (Toxic effect of latex, accidental (unintentional), initial encounter) compared with T65.811S (Toxic effect of latex, accidental (unintentional), sequela), from the official CMS tabular data. T65.811A and T65.811S code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. T65.811A and T65.811S 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.
