About F15Z48Z

F15Z48Z is the ICD-10-PCS code for a vestibular assessment procedure on the none using a sinusoidal vertical axis rotational approach with vestibular / balance (qualifier: none). In ICD-10-PCS, vestibular assessment means measurement of the vestibular system and related functions.

In plain terms, this corresponds to rotation tests, the ICD-9-CM procedure title it maps to (95.45).

The same procedure with a different approach is coded F15Z08Z (bithermal, binaural caloric irrigation), F15Z18Z (bithermal, monaural caloric irrigation), F15Z28Z (unithermal binaural screen), F15Z38Z (oscillating tracking), F15Z58Z (dix-hallpike dynamic) and F15Z68Z (computerized dynamic posturography).

With a different device, use F15Z4ZZ (none).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
