About E29

E29 is the ICD-10-CM diagnosis code for testicular dysfunction. It belongs to block E20-E35 (disorders of other endocrine glands) and chapter 4 (endocrine, nutritional and metabolic diseases). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: E29.0 (hyperfunction), E29.1 (hypofunction), E29.8 (dysfunction) and E29.9 (unspecified).

Don't report E29 together with the conditions in its Excludes1 note: androgen insensitivity syndrome (E34.5-), azoospermia or oligospermia NOS (N46.0-N46.1), isolated gonadotropin deficiency (E23.0) and Klinefelter's syndrome (Q98.0-Q98.1, Q98.4).

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