ICD-10 Code E27 – Other disorders of adrenal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E27 – Other disorders of adrenal gland
What it is
E27 is the ICD-10-CM category for adrenal gland disorders that do not fit a more specific adrenal diagnosis. Use it when the record identifies an adrenal problem, but the exact disorder is not documented.
Clinical signs
Clinical features vary; refer to documentation. Adrenal disorders may involve hormone-related findings, abdominal or flank symptoms, weakness, or incidental imaging abnormalities, depending on the underlying condition.
When to use this code
Use E27 when the provider documents a nonspecific adrenal disorder, such as an adrenal abnormality or other adrenal condition without a more precise code. It can also apply when the chart confirms adrenal disease but does not name the exact subtype. Check documentation before assigning it.
Do not use for
Do not use E27 when the record supports a more specific adrenal diagnosis, such as a distinct endocrine disorder or a documented adrenal mass with a different code. Do not guess the subtype.
Coding tip
If the note says only “adrenal disorder,” query for specificity before defaulting to E27.
