Specific Coding for Nonrheumatic tricuspid valve disordersOverview

Non-specific codes like I36 require more characters. Use one of these billable codes instead:

  • Use I36.0 for Nonrheumatic tricuspid (valve) stenosis

  • Use I36.1 for Nonrheumatic tricuspid (valve) insufficiency

  • Use I36.2 for Nonrheumatic tricuspid (valve) stenosis with insufficiency

  • Use I36.8 for Other nonrheumatic tricuspid valve disorders

  • Use I36.9 for Nonrheumatic tricuspid valve disorder, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to I36: its own notes plus those printed at Chapter 9. A note printed at a category, block or chapter applies to every code under it.

Excludes1

  • tricuspid valve disorders of unspecified cause (I07.-)
  • tricuspid valve disorders specified as congenital (Q22.4, Q22.8, Q22.9)
  • tricuspid valve disorders specified as rheumatic (I07.-)
  • tricuspid valve disorders with aortic and/or mitral valve involvement (I08.-)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 9 (I00-I99) Diseases of the circulatory system applies to 1,433 codes
  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
  • endocrine, nutritional and metabolic diseases (E00-E88)

Questions About I36Overview

What is the ICD-10 code for nonrheumatic tricuspid valve disorders?

I36 is the ICD-10-CM category for nonrheumatic tricuspid valve disorders, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is I36 (Nonrheumatic tricuspid valve disorders) a billable code?

No. This is a category header that groups the codes for nonrheumatic tricuspid valve disorders, and headers cannot be submitted on claims. Claims for nonrheumatic tricuspid valve disorders need a more specific code from this category, such as I36.0, I36.1, and I36.2.

Can I36 be reported with a code from I07?

Not as a rule. The Excludes1 note on I36 lists "tricuspid valve disorders of unspecified cause (I07.-)". 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).
