M60 is a non-billable ICD-10-CM category code for myositis, so it cannot be submitted on claims. Use a more specific code from this category instead, such as M60.000, M60.001, M60.002, and M60.003.

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to M60: its own notes plus those printed at block M60-M63 and Chapter 13. A note printed at a category, block or chapter applies to every code under it.

Excludes1

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

From Block M60-M63 Disorders of muscles applies to 420 codes
  • dermatopolymyositis (M33.-)

  • myopathy in scleroderma (M34.-)
  • myopathy in Sjögren's syndrome (M35.03)
  • myopathy in systemic lupus erythematosus (M32.-)

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.

Excludes1 2

These codes carry an Excludes1 note naming M60: they are not reported together with it, unless the two conditions are unrelated.

Excludes2 1

These codes carry an Excludes2 note naming M60: its condition is not part of those codes, and both may be reported when the patient has both.

Clinical InformationClinical

  • Myositis

    inflammation of a muscle or muscle tissue.

Patient EducationClinical

Myositis

Myositis means inflammation of the muscles that you use to move your body. An injury, infection, or autoimmune disease can cause it. Two specific kinds are polymyositis and dermatomyositis. Polymyositis causes muscle weakness, usually in the muscles closest to the trunk of your body.

Questions About M60Overview

What is the ICD-10 code for myositis?

M60 is the ICD-10-CM category for myositis, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is M60 (Myositis) a billable code?

No. This is a category header that groups the codes for myositis, and headers cannot be submitted on claims. Claims for myositis need a more specific code from this category, such as M60.000, M60.001, and M60.002.

Can M60 be reported with a code from M33?

Not as a rule. The Excludes1 note at block M60-M63, which applies to M60, lists "dermatopolymyositis (M33.-)". 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).
