B05 is a non-billable ICD-10-CM category code for measles, so it cannot be submitted on claims. Use a more specific code from this category instead, such as B05.0, B05.1, B05.2, and B05.3.

Specific Coding for MeaslesOverview
Non-specific codes like B05 require more characters. Use one of these billable codes instead:
Use B05.0 for Measles complicated by encephalitis
Use B05.1 for Measles complicated by meningitis
Use B05.2 for Measles complicated by pneumonia
Use B05.3 for Measles complicated by otitis media
Use B05.4 for Measles with intestinal complications
B05.8 for Measles with other complications
Use B05.81 for Measles keratitis and keratoconjunctivitis
Use B05.89 for Other measles complications
Use B05.9 for Measles without complication

Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
- subacute sclerosing panencephalitis (A81.1)
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.
- carrier or suspected carrier of infectious disease (Z22.-)

Questions About B05Overview
What is the ICD-10 code for measles?
B05 is the ICD-10-CM category for measles, but it is a non-billable header: claims need a more specific code from this category, listed on this page.
Is B05 (Measles) a billable code?
No. This is a category header that groups the codes for measles, and headers cannot be submitted on claims. Claims for measles need a more specific code from this category, such as B05.0, B05.1, and B05.2.
Can B05 be reported with A81.1?
Not as a rule. The Excludes1 note on B05 lists "subacute sclerosing panencephalitis (A81.1)". 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).
