Benign Tumors

Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.

Questions About D10.39Overview

Is D10.39 (Benign neoplasm of other and unspecified parts of mouth) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report benign neoplasm of other parts of mouth on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does D10.39 group to?

When benign neoplasm of other parts of mouth is the principal diagnosis on an inpatient stay, it groups to MS-DRG 157, 158, 159, with relative weights from 0.7085 to 1.7168 depending on complications. Higher weights mean higher Medicare reimbursement.

What is the ICD-9 equivalent of D10.39?

Under the General Equivalence Mappings, benign neoplasm of other parts of mouth converts to ICD-9-CM 210.4 (benign neo mouth NEC/NOS). The mapping is approximate, so confirm the match fits the documentation.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
