ICD-10 Code E27.9 – Disorder of adrenal gland, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E27.9 – Disorder of adrenal gland, unspecified
What it is
E27.9 identifies an adrenal gland disorder when the record does not specify the exact adrenal condition. Use it for adrenal abnormalities documented without a clearer diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Findings may include signs of adrenal dysfunction, but the chart must support a nonspecific adrenal disorder rather than a named endocrine condition.
When to use this code
Use E27.9 when the provider documents an adrenal gland disorder, adrenal abnormality, or adrenal dysfunction without naming the specific disease. It is appropriate when the note lacks enough detail for a more specific code.
Choose this code only after reviewing the record for a definitive diagnosis. If the documentation later identifies a specific adrenal disorder, code that condition instead.
Do not use for
Do not use E27.9 when the chart supports a specific adrenal diagnosis, such as a named endocrine disorder. Do not use it as a default if the provider has documented a more precise condition.
Coding tip
Query the provider when the adrenal problem is unclear, because unspecified codes should be used only when documentation remains nonspecific.
