T81.510A vs T81.510D
T81.510A (Adhesions due to foreign body accidentally left in body following surgical operation, initial encounter) compared with T81.510D (Adhesions due to foreign body accidentally left in body following surgical operation, subsequent encounter), from the official CMS tabular data. T81.510A and T81.510D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. T81.510A and T81.510D 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.
