S40.271A vs S40.271D
S40.271A (Other superficial bite of right shoulder, initial encounter) compared with S40.271D (Other superficial bite of right shoulder, subsequent encounter), from the official CMS tabular data. S40.271A and S40.271D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S40.271A and S40.271D 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.
