About 09B47ZX

09B47ZX is the ICD-10-PCS code for a excision procedure on the left external auditory canal using a via natural or artificial opening approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to biopsy of external ear, the ICD-9-CM procedure title it maps to (18.12).

For a different body part, codes include 09B37ZX (right external auditory canal), 09B77ZX (right tympanic membrane), 09B87ZX (left tympanic membrane), 09BF7ZX (right eustachian tube), 09BG7ZX (left eustachian tube), 09BL7ZX (nasal turbinate) and 1 more.

The same procedure with a different approach is coded 09B40ZX (open), 09B43ZX (percutaneous), 09B44ZX (percutaneous endoscopic), 09B48ZX (via natural or artificial opening endoscopic) and 09B4XZX (external).

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.
