S40.022A vs S40.022D
S40.022A (Contusion of left upper arm, initial encounter) compared with S40.022D (Contusion of left upper arm, subsequent encounter), from the official CMS tabular data. S40.022A and S40.022D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S40.022A and S40.022D 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.
