Detected on CT or MRI scans performed for other reasons, such as abdominal pain or injury.
ICD-10 Code Families
Complete code families applicable to D49.7
When to use each related code
| Description | When to use |
|---|---|
| Adrenal gland mass found incidentally on imaging. | Use when adrenal mass is discovered unexpectedly during imaging for unrelated reasons. |
| Non-cancerous adrenal tumor producing excess hormones. | Use when adrenal mass is confirmed as benign and associated with hormone overproduction (e.g., Cushing's, Conn's). |
| Cancerous tumor of the adrenal gland. | Use when adrenal mass is confirmed as malignant based on biopsy or imaging characteristics. |
Best-practice checklist
- ✓Document size, location, and imaging characteristics of adrenal mass.
- ✓Record hormonal evaluation results (cortisol, aldosterone, catecholamines).
- ✓Note any symptoms or signs related to adrenal hormone excess or deficiency.
- ✓Specify if the mass is benign or suspicious for malignancy based on imaging.
- ✓Include relevant ICD-10 codes (e.g., D35.0, E27.1) and CPT codes for imaging/biopsy.
Common pitfalls to avoid
Incidentalomas require confirmatory imaging and/or biopsy to rule out malignancy, impacting accurate coding (e.g., D35.0 vs. C74). This poses CDI and compliance risks.
Coding requires specifying laterality (right, left, bilateral). Missing laterality information for adrenal incidentalomas leads to coding errors and claim denials.
Distinguishing functional (e.g., hormone-secreting) from non-functional incidentalomas is crucial for correct coding and impacts medical necessity reviews for further workup.
Best-practice tips
- 01Thorough imaging workup: size, shape, features (ICD-10 S84.8)
- 02Biochemical evaluation for hormone excess (CPT 80000-89399, CDI)
- 03Risk stratification for malignancy (NCCN guidelines, healthcare compliance)
- 04Regular follow-up imaging for stable incidentalomas (ACR Appropriateness Criteria)
- 05Surgical consult if functional or suspicious for malignancy (CDI, quality measures)

Ready-to-paste narrative
Patient presents with an adrenal incidentaloma, an incidentally discovered adrenal mass or adrenal nodule, found during imaging performed for reasons unrelated to adrenal function. The patient's chief complaint for the original imaging study was (reason for initial imaging). The adrenal incidentaloma was identified on (imaging modality, e.g., CT abdomen, MRI abdomen) and is described as (size, location, and characteristics of the incidentaloma, e.g., a 1.5 cm, well-circumscribed, homogenous, right adrenal mass). Patient denies any symptoms suggestive of adrenal hormone excess, such as hypertension, weight gain, muscle weakness, easy bruising, or hirsutism. No history of adrenal disorders. Review of systems is otherwise unremarkable. Differential diagnosis includes benign adrenal adenoma, adrenocortical carcinoma, pheochromocytoma, myelolipoma, and metastasis. Further evaluation to characterize the adrenal incidentaloma is recommended and will include biochemical evaluation for hormone overproduction including assessment of serum metanephrines, plasma aldosterone concentration and plasma renin activity, and a 24-hour urine collection for free cortisol. Follow-up imaging with (imaging modality) in (timeframe) is planned to assess for growth. Patient education provided regarding adrenal incidentalomas, including the importance of follow-up and potential management options. ICD-10 code D44.7 (neoplasm of uncertain behavior of adrenal gland) may be applicable, pending further evaluation. CPT codes for imaging and laboratory tests will be documented separately.
Common questions and answers
What is the most effective imaging protocol for characterizing an incidentally discovered adrenal mass and differentiating between benign adrenal adenoma and other adrenal lesions like pheochromocytoma or adrenocortical carcinoma?+
Characterizing an incidentally discovered adrenal mass requires a multi-modal approach. While unenhanced CT is often the initial imaging modality, further evaluation depends on size and imaging characteristics. For masses < 4cm with benign features (e.g., low attenuation on unenhanced CT), hormonal evaluation is recommended. For larger masses or those with suspicious features (e.g., irregular margins, heterogeneous enhancement), contrast-enhanced CT or MRI is warranted. Chemical shift MRI can aid in differentiating adrenal adenoma from other lesions. In cases where pheochromocytoma is suspected, consider plasma or urinary metanephrines and normetanephrines. If adrenocortical carcinoma is a concern, serum cortisol, DHEAS, and aldosterone levels may be useful. Explore how S10.AI can integrate these imaging and hormonal data points to assist in risk stratification and clinical decision-making for adrenal incidentaloma management.
When should surgical intervention be considered for an adrenal incidentaloma and what factors influence the decision between adrenalectomy vs. active surveillance for patients with non-functioning adrenal adenomas?+
The decision for surgical intervention versus active surveillance for an adrenal incidentaloma depends on several factors, including functionality, size, and imaging characteristics. Functioning tumors, such as those causing Cushing's syndrome or primary aldosteronism, typically require surgical removal. Non-functioning adenomas < 4cm with benign imaging features (e.g., homogenous, low attenuation on CT) can often be managed with active surveillance, including repeat imaging and hormonal assessment at intervals. However, surgical intervention should be considered for non-functioning adenomas > 4cm or those demonstrating concerning imaging features such as rapid growth, irregular borders, or heterogeneous enhancement, as these raise the suspicion for malignancy. Consider implementing S10.AI's insights to facilitate patient-specific risk assessment and guide decisions regarding surgical intervention vs. active surveillance.
How does the management of an adrenal incidentaloma differ in patients with a history of extra-adrenal malignancy, and what specific imaging or follow-up protocols are recommended for these individuals?+
Managing adrenal incidentalomas in patients with a history of extra-adrenal malignancy requires heightened vigilance. The possibility of an adrenal metastasis should be considered, especially if the primary cancer is known to metastasize to the adrenal glands (e.g., lung, breast, kidney). Further investigation with contrast-enhanced CT or MRI is often recommended, along with a thorough evaluation for hormonal activity. FDG-PET/CT may be helpful in differentiating benign adenomas from metastases in certain cases. Close follow-up, including repeat imaging and hormonal assessment, is crucial.
