What is the ICD-10 code for a benign intracranial mass?

The ICD-10 code for a benign intracranial mass, specifically a supratentorial tumor, is D33.0. This code is used when the mass is confirmed as benign through biopsy.

How do you code a metastatic brain tumor?

For a metastatic brain tumor, use ICD-10 code C79.31. Ensure the primary malignancy is coded first, followed by C79.31 for the secondary brain involvement.

Code	Description	When to Use	Key Documentation
D33.0	Benign neoplasm of brain, supratentorial	Use when a benign supratentorial mass is confirmed by biopsy.	Biopsy confirming benign nature MRI showing supratentorial location
C79.31	Secondary malignant neoplasm of brain	Use when a brain tumor is confirmed as metastatic from another primary site.	Pathology confirming secondary origin Imaging showing metastatic lesions

Documentation & Coding Risks

Avoid these common issues when documenting Intracranial Mass.

Lack of molecular data documentation

Impact

Clinical: Inaccurate tumor classification, Regulatory: Non-compliance with coding standards, Financial: Potential claim denials

Mitigation

Ensure molecular testing results are included in the report, Link molecular data to diagnosis

Misusing R90.0 after biopsy confirms glioma

Impact

Reimbursement: Incorrect use can lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation

Use R90.0 only for undetermined masses pre-biopsy.

Unspecified codes

Impact

High audit risk for using unspecified codes without detailed documentation.

Mitigation

Ensure all documentation includes specific anatomical and pathological details.
