About N49

N49 is the ICD-10-CM diagnosis code for inflammatory disorders of male genital organs, not elsewhere classified. It belongs to block N40-N53 (diseases of male genital organs) and chapter 14 (diseases of the genitourinary system). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: N49.0 (vesicle), N49.1 (deferens), N49.2 (scrotum), N49.3 (gangrene), N49.8 (organs) and N49.9 (organ).

Don't report N49 together with the conditions in its Excludes1 note: inflammation of penis (N48.1, N48.2-) and orchitis and epididymitis (N45.-).

Use an additional code (B95-B97), to identify infectious agent.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
