A54.31 vs P39.1
A54.31 (Gonococcal conjunctivitis) compared with P39.1 (Neonatal conjunctivitis and dacryocystitis), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. P39.1 carries an Excludes1 note covering A54.31: “gonococcal conjunctivitis (A54.31)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
Yes, when both are documented. P39.1 carries an Excludes2 note covering A54.31: “congenital gonococcal infection (A54.-)”
Excludes2 marks distinct conditions — both may be reported when both are documented.
