A39.82 ICD-10-CM Code: Meningococcal retrobulbar neuritis

Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.

Inpatient Payment Groups (MS-DRG)

Potential MS-DRG participation — not a DRG assignment.

MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v44, Appendix B.

  • MS-DRG 123 — NEUROLOGICAL EYE DISORDERS (MDC 02)
  • MS-DRG 791 — PREMATURITY WITH MAJOR PROBLEMS (MDC 15)
  • MS-DRG 793 — FULL TERM NEONATE WITH MAJOR PROBLEMS (MDC 15)

A diagnosis appearing in a group's logic does not by itself determine the DRG assigned to a stay; the grouper uses the full claim.

Code Overview

Meningococcal retrobulbar neuritis is a billable ICD-10-CM diagnosis code (A39.82).

Indexed Clinical Terms (3)

Official source data — entries quoted as published, in the Index’s own lookup phrasing

Clinical term phrases from the official ICD-10-CM Index to Diseases and Injuries that map to this code. These are alphabetic-index entries shown as the Index writes them — lookup phrasing, not necessarily the wording of a final diagnosis.

MS-DRG Grouper Relationships (FY2027)

Potential MS-DRG participation — not a DRG assignment.

FY2027 MS-DRG: CC — Complication or Comorbidity. Reported as a secondary diagnosis, this code raises the stay's MS-DRG severity tier — except when the principal diagnosis is one of 10 clinically related codes on its CMS exclusion list.

Named in the grouper logic of 3 MS-DRGs: DRG 123 (MDC 02), DRG 791 (MDC 15), DRG 793 (MDC 15).

From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.

Clinical classification (AHRQ CCSR):EYE006 — Neuro-ophthalmology (default); INF003 — Bacterial infections.

Related Codes

Same clinical process (MS-DRG)

Acts as CC — raises the severity of other admissions. CMS groups these diagnoses into one MS-DRG principal-diagnosis exclusion process — a CC/MCC on this list never raises severity when the principal diagnosis is also on it.

A39.89 — Other meningococcal infections, A39.9 — Meningococcal infection, unspecified, A49.3 — Mycoplasma infection, unspecified site, A49.8 — Other bacterial infections of unspecified site, A49.9 — Bacterial infection, unspecified, B92 — Sequelae of leprosy, B94.2 — Sequelae of viral hepatitis, B94.8 — Sequelae of other specified infectious and parasitic diseases, B94.9 — Sequelae of unspecified infectious and parasitic disease

Same clinical category (CCSR)

AHRQ's Clinical Classifications Software groups these diagnoses under the same clinical categories (Neuro-ophthalmology, Bacterial infections).

Same Index main term, other category

The ICD-10-CM Index to Diseases and Injuries files this code under the main term “Neuritis”; these codes share that main term but sit in a different category of the Tabular List.

A52.15 — Late syphilitic neuropathy (syphilitic), A69.22 — Other neurologic disorders in Lyme disease (cranial nerve, due to Lyme disease), B02.21 — Postherpetic geniculate ganglionitis (geniculate ganglion, due to herpes), B02.29 — Other postherpetic nervous system involvement (postherpetic, postzoster), B89 — Unspecified parasitic disease (acoustic, in, parasitic disease NEC), B99 — Other and unspecified infectious diseases (acoustic, in, infectious disease NEC), E51.11 — Dry beriberi (endemic), E85.4 — Organ-limited amyloidosis (amyloid, any site), G36.0 — Neuromyelitis optica [Devic] (optic, in myelitis), G51.1 — Geniculate ganglionitis (geniculate ganglion), G51.8 — Other disorders of facial nerve (facial), G52.0 — Disorders of olfactory nerve (olfactory nerve), G52.2 — Disorders of vagus nerve (vagus), G52.3 — Disorders of hypoglossal nerve (hypoglossal), G52.8 — Disorders of other specified cranial nerves (accessory), G54.5 — Neuralgic amyotrophy (shoulder-girdle), G56.1 — Other lesions of median nerve (thenar), G57.9 — Unspecified mononeuropathy of lower limb (ilioinguinal), G58.8 — Other specified mononeuropathies (specified nerve NEC), G60.0 — Hereditary motor and sensory neuropathy (Déjérine-Sottas), +18 more
