Specific Coding for Nonrheumatic pulmonary valve disordersOverview

Non-specific codes like I37 require more characters. Use one of these billable codes instead:

  • Use I37.0 for Nonrheumatic pulmonary valve stenosis

  • Use I37.1 for Nonrheumatic pulmonary valve insufficiency

  • Use I37.2 for Nonrheumatic pulmonary valve stenosis with insufficiency

  • Use I37.8 for Other nonrheumatic pulmonary valve disorders

  • Use I37.9 for Nonrheumatic pulmonary valve disorder, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to I37: 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

  • pulmonary valve disorder specified as rheumatic (I09.89)

Excludes2

Questions About I37Overview

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

I37 is the ICD-10-CM category for nonrheumatic pulmonary valve disorders, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is I37 (Nonrheumatic pulmonary valve disorders) a billable code?

No. This is a category header that groups the codes for nonrheumatic pulmonary valve disorders, and headers cannot be submitted on claims. Claims for nonrheumatic pulmonary valve disorders need a more specific code from this category, such as I37.0, I37.1, and I37.2.

Can I37 be reported with Q22.1?

Not as a rule. The Excludes1 note on I37 lists "pulmonary valve disorder specified as congenital (Q22.1, Q22.2, Q22.3)". 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).
