S37.591A vs S37.591S
S37.591A (Other injury of fallopian tube, unilateral, initial encounter) compared with S37.591S (Other injury of fallopian tube, unilateral, sequela), from the official CMS tabular data. S37.591A and S37.591S code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S37.591A and S37.591S 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.
