S61.303A vs S61.303D
S61.303A (Unspecified open wound of left middle finger with damage to nail, initial encounter) compared with S61.303D (Unspecified open wound of left middle finger with damage to nail, subsequent encounter), from the official CMS tabular data. S61.303A and S61.303D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S61.303A and S61.303D 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.
