Is Q01 a billable ICD-10-CM code?

No. Q01 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does Q01 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 Q01?

Q01 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

Q01

Q01 — Encephalocele

Non-billable headerICD-10-CM

Q01 is a non-billable header ICD-10-CM code for encephalocele. 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.

Meckel-Gruber syndrome (Q61.9)

Includes

Conditions this code covers.

Arnold-Chiari syndrome, type III
encephalocystocele
encephalomyelocele
hydroencephalocele
hydromeningocele, cranial
meningocele, cerebral
meningoencephalocele

Other codes that can never be billed with Q01

These codes carry an Excludes1 note pointing at Q01. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q01 alone.

Q07.0Arnold-Chiari syndrome
Q75Other congenital malformations of skull and face bones

Risk adjustment

Q01 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 Q01

5 child codes. Green means billable.
