D32.9Benign neoplasm of meninges, unspecified

D32.9 is the ICD-10-CM diagnosis code for benign neoplasm of meninges, unspecified. It belongs to category D32 (benign neoplasm of meninges), block D10-D36 (benign neoplasms, except benign neuroendocrine tumors) and chapter 2 (neoplasms). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within D32, choose D32.9 (unspecified) only when documentation doesn't support a more specific option: cerebral meninges (D32.0) and spinal meninges (D32.1).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 054 (Nervous System Neoplasms with MCC, relative weight 1.5194) and DRG 055 (Nervous System Neoplasms without MCC, relative weight 1.0296), in MDC 01 (Diseases and Disorders of the Nervous System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 225.2 (benign neoplasm of cerebral meninges).
