ICD10 code of Adenoid Cystic Carcinoma and ICD9 code

Adenoid Cystic Carcinoma (ACC) is typically coded under the International Classification of Diseases, 10th Revision (ICD-10) using specific site-dependent codes, most commonly C06.9 (Malignant neoplasm of mouth, unspecified) or codes reflecting the primary site (e.g., salivary glands, lacrimal glands, or respiratory tract). In the ICD-9 system, which has been largely superseded, Adenoid Cystic Carcinoma was generally categorized under 142.9 (Malignant neoplasm of major salivary gland, unspecified).

How are ICD codes determined for Adenoid Cystic Carcinoma?

Because Adenoid Cystic Carcinoma is a rare malignancy that can arise in various anatomical locations, there is no single "ACC code." Instead, the ICD system requires clinicians to use a combination of the histological type (often identified via morphology codes like 8200/3) and the site-specific code. This ensures that the clinical registry accurately reflects where the Adenoid Cystic Carcinoma originated, such as the head and neck, breast, or skin.

Why is accurate coding important for Adenoid Cystic Carcinoma patients?

Precise coding is vital for tracking the outcomes of the 119 members of the DiseaseMaps community living with Adenoid Cystic Carcinoma. Accurate coding helps researchers analyze long-term survival data, monitor the prevalence of Adenoid Cystic Carcinoma across different populations, and ensure that insurance providers recognize the necessity of specialized, often intensive, treatment protocols.

What are the common anatomical sites for Adenoid Cystic Carcinoma?

Adenoid Cystic Carcinoma is characterized by its slow growth and tendency for perineural invasion. Common primary sites include:

• Major and minor salivary glands (the most frequent site)


• Lacrimal glands (the eyes)


• Upper respiratory tract (nasal cavity and sinuses)


• Breast tissue


• Skin and external auditory canal

Next steps

• Request a copy of your pathology report to confirm the exact histological classification of your Adenoid Cystic Carcinoma.


• Consult with an oncologist specializing in rare head and neck cancers to discuss your specific staging.


• Join the 119 members on DiseaseMaps.org to share experiences and find resources for managing this rare condition.


• Review clinical trials specifically targeting the molecular pathways of Adenoid Cystic Carcinoma via the NIH clinical trials registry.
