M30 is a non-billable ICD-10-CM category code for polyarteritis nodosa and related conditions, so it cannot be submitted on claims. Use a more specific code from this category instead, such as M30.0, M30.1, M30.2, and M30.3.

Specific Coding for Polyarteritis nodosa and related conditionsOverview

Non-specific codes like M30 require more characters. Use one of these billable codes instead:

  • Use M30.0 for Polyarteritis nodosa

  • Use M30.1 for Polyarteritis with lung involvement [Churg-Strauss]

  • Use M30.2 for Juvenile polyarteritis

  • Use M30.3 for Mucocutaneous lymph node syndrome [Kawasaki]

  • Use M30.8 for Other conditions related to polyarteritis nodosa

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to M30: its own notes plus those printed at block M30-M36 and Chapter 13. A note printed at a category, block or chapter applies to every code under it.

Further defines, or gives examples of, the content of the category.

From Block M30-M36 Systemic connective tissue disorders applies to 84 codes
  • autoimmune disease NOS
  • collagen (vascular) disease NOS
  • systemic autoimmune disease
  • systemic collagen (vascular) disease

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

On M30 itself
  • microscopic polyarteritis (M31.7)
From Block M30-M36 Systemic connective tissue disorders applies to 84 codes
  • autoimmune disease, single organ or single cell-type -code to relevant condition category

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 13 (M00-M99) Diseases of the musculoskeletal system and connective tissue applies to 6,687 codes
  • arthropathic psoriasis (L40.5-)
  • certain conditions originating in the perinatal period (P04-P96)

  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

Notes

General instructions on how these codes are used.

Patient EducationClinical

Vasculitis

Vasculitis is an inflammation of the blood vessels. It happens when the body's immune system attacks the blood vessel by mistake. It can happen because of an infection, a medicine, or another disease. The cause is often unknown.

Questions About M30Overview

What is the ICD-10 code for polyarteritis nodosa and related conditions?

M30 is the ICD-10-CM category for polyarteritis nodosa and related conditions, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is M30 (Polyarteritis nodosa and related conditions) a billable code?

No. This is a category header that groups the codes for polyarteritis nodosa and related conditions, and headers cannot be submitted on claims. Claims for polyarteritis nodosa and related conditions need a more specific code from this category, such as M30.0, M30.1, and M30.2.

Can M30 be reported with M31.7?

Not as a rule. The Excludes1 note on M30 lists "microscopic polyarteritis (M31.7)". 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).
