Billable/Specific Code

Manifestation Code

I39 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
Short description: Endocarditis and heart valve disord in dis classd elswhr
The 2022 edition of ICD-10-CM I39 became effective on October 1, 2021.
This is the American ICD-10-CM version of I39 - other international versions of ICD-10 I39 may differ.

ICD-10-CM Coding Rules

I39 describes the manifestation of an underlying disease, not the disease itself.

Code First

Code First Help

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.

underlying disease, such as:
Q fever (
ICD-10-CM Diagnosis Code A78
Q fever
Applicable To
- Infection due to Coxiella burnetii
- Nine Mile fever
- Quadrilateral fever
A78
)

Type 1 Excludes

Type 1 Excludes Help

A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as I39. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
