ICD-10-CM Code G99.2
Myelopathy in diseases classified elsewhere

BILLABLE
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
Manifestation
Manifestation Code
Certain ICD-10-CM codes identify an underlying condition known as an etiology code. Conditions that arise as a result of an underlying condition (etiology), are referred to as Manifestations. In ICD-10-CM, etiology codes must be coded first, followed by the manifestation codes. When a condition requires etiology and manifestation codes, there is a "use additional code" note following the etiology code and a "code first" note following the manifestation code.
| ICD-10 from 2011 - 2016

G99.2 is a billable ICD code used to specify a diagnosis of myelopathy in diseases classified elsewhere. A 'billable code' is detailed enough to be used to specify a medical diagnosis.


The ICD code G99 is used to code Nervous system disease

Nervous system disease refers to a general class of medical conditions affecting the nervous system.

Specialty: Neurology
MeSH Codes: D009422, D009422, D009422, D009422, D009422

Type-1 Excludes
Type-1 Excludes mean the conditions excluded are mutually exclusive and should never be coded together. Excludes 1 means "do not code here."
Myelopathy in:
Intervertebral disease (M50.0-, M51.0-) - instead, use code M50.0-
Spondylosis (M47.0-, M47.1-) - instead, use code M47.0-

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)

Myelopathy in other diseases classified elsewhere (approximate match)

This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code G99.2 and a single ICD9 code, 336.3 is an approximate match for comparison and conversion purposes.
