S37.501A vs S37.501D
S37.501A (Unspecified injury of fallopian tube, unilateral, initial encounter) compared with S37.501D (Unspecified injury of fallopian tube, unilateral, subsequent encounter), from the official CMS tabular data. S37.501A and S37.501D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S37.501A and S37.501D 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.
