T82.510A vs T82.510D
T82.510A (Breakdown (mechanical) of surgically created arteriovenous fistula, initial encounter) compared with T82.510D (Breakdown (mechanical) of surgically created arteriovenous fistula, subsequent encounter), from the official CMS tabular data. T82.510A and T82.510D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. T82.510A and T82.510D 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.
