Is Q05 a billable ICD-10-CM code?

No. Q05 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does Q05 sit in the tabular list?

Congenital malformations, deformations and chromosomal abnormalities (Q00-QA0), in the block Congenital malformations of the nervous system (Q00-Q07).

What cannot be coded together with Q05?

Q05 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

Q05

Q05 — Spina bifida

Non-billable headerICD-10-CM

Q05 is a non-billable header ICD-10-CM code for spina bifida. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

Arnold-Chiari syndrome, type II (Q07.0-)
spina bifida occulta (Q76.0)

Use additional code

Add a secondary code to capture the detail described below.

code for any associated paraplegia (paraparesis) (G82.2-)

Includes

Conditions this code covers.

hydromeningocele (spinal)
meningocele (spinal)
meningomyelocele
myelocele
myelomeningocele
rachischisis
spina bifida (aperta)(cystica)
syringomyelocele

Other codes that can never be billed with Q05

These codes carry an Excludes1 note pointing at Q05. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q05 alone.

Q03Congenital hydrocephalus
Q76.0Spina bifida occulta
G91Hydrocephalus

Risk adjustment

Q05 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead Q05

10 child codes. Green means billable.
