Q05 — Spina bifida
Is Q05 billable?
No — Q05 is a non-billable header code. Q05 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 10 billable codes beneath Q05.

Excludes1 — never code together
The conditions below can never be reported together with Q05 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Use additional code
Report an additional code alongside Q05 to fully describe the condition. Q05 is sequenced first.

How long has Q05 existed?
Q05 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with Q05?
ICD-10-CM declares these codes mutually exclusive with Q05 — exactly one of each pair can be correct for a given encounter.
