Q05 is a non-billable ICD-10-CM category code for spina bifida, so it cannot be submitted on claims. Use a more specific code from this category instead, such as Q05.0, Q05.1, Q05.2, and Q05.3.

Type 1 Excludes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
Patient EducationClinical
Spina Bifida
Spina bifida is a neural tube defect - a type of birth defect of the brain, spine, or spinal cord. It happens if the spinal column of the fetus doesn't close completely during the first month of pregnancy. This can damage the nerves and spinal cord. Screening tests during pregnancy can check for spina bifida.
