ICD-10 Code E28.8 – Other ovarian dysfunction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E28.8 – Other ovarian dysfunction
What it is
E28.8 identifies ovarian dysfunction that does not fit a more specific ICD-10 category. Use it when documentation indicates abnormal ovarian function, but the exact disorder is not named.
Clinical signs
Clinical features vary; refer to documentation. Findings may include menstrual irregularity, anovulation, or other evidence of impaired ovarian function, but the record should support the nonspecific diagnosis.
When to use this code
Use this code when the clinician documents “other ovarian dysfunction” or a similar nonspecific ovarian disorder. It is appropriate when the record confirms ovarian dysfunction but does not identify a more specific codeable condition. If the note names a distinct ovarian disorder, code that diagnosis instead.
Do not use for
Do not use E28.8 when documentation supports a more specific ovarian diagnosis, such as ovarian failure or PCOS. Also avoid it when the problem is only a menstrual symptom without confirmed ovarian dysfunction.
Coding tip
Query the provider if the chart says “ovarian dysfunction” but does not clarify whether a more specific diagnosis applies.
