ICD-10 Code D44.7 – Neoplasm of uncertain behavior of aortic body and other paraganglia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D44.7 – Neoplasm of uncertain behavior of aortic body and other paraganglia
What it is
D44.7 identifies a growth in the aortic body or other paraganglia whose behavior cannot yet be determined as benign or malignant. Use it when the record documents uncertain behavior for a paraganglionic tumor.
Clinical signs
Clinical features vary; refer to documentation. These tumors may be found as a mass on imaging, during evaluation of symptoms from local compression, or after pathology shows uncertain biologic behavior.
When to use this code
Use D44.7 when the provider documents a neoplasm of uncertain behavior involving the aortic body or another paraganglion. It fits cases where pathology, biopsy, or the final assessment does not establish malignancy or benignity. If the site is different, check documentation before coding.
Do not use for
Do not use this code for clearly malignant paraganglioma or for benign tumors with documented behavior. If the diagnosis is another endocrine or neuroendocrine neoplasm, select the more specific code.
Coding tip
Code from the provider’s final documented behavior and anatomic site, and query if “paraganglioma” is stated without uncertain behavior.
