- Not Chronic
B06.02 is a billable ICD-10-CM diagnosis code for rubella meningitis. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 97 through 99, 791, 793. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 24 closely related codes. Coders also document this condition as meningitis caused by Rubella virus. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Meningitis and Viral infection.

Meningitis
Meningitis is inflammation of the thin tissue that surrounds the brain and spinal cord, called the meninges. There are several types of meningitis. The most common is viral meningitis. You get it when a virus enters the body through the nose or mouth and travels to the brain. Bacterial meningitis is rare but can be deadly.

Questions About B06.02Overview
What is the ICD-10 code for rubella meningitis?
The ICD-10-CM code for rubella meningitis is B06.02 (sometimes written as B0602). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is B06.02 (Rubella with neurological complications) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report rubella meningitis on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does B06.02 group to?
When rubella meningitis is the principal diagnosis on an inpatient stay, it groups to MS-DRG 793, 791, 98, 99, 97, with relative weights from 1.5249 to 4.2192 depending on complications. Higher weights mean higher Medicare reimbursement.
Is B06.02 a CC or MCC?
CMS lists B06.02 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 24 closely related codes in its exclusion list.
Can B06.02 be reported with P35.0?
Not as a rule. The Excludes1 note at B06, which applies to B06.02, lists "congenital rubella (P35.0)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
