About 4A098CZ
4A098CZ is the ICD-10-PCS code for a measurement procedure on the respiratory using a via natural or artificial opening endoscopic approach with rate. In ICD-10-PCS, measurement means determining the level of a physiological or physical function at a point in time.
In plain terms, this corresponds to other nonoperative respiratory measurements, the ICD-9-CM procedure title it maps to (89.38).
For a different body part, codes include 4A028CZ (cardiac) and 4A0H8CZ (products of conception, cardiac).
The same procedure with a different approach is coded 4A097CZ (via natural or artificial opening) and 4A09XCZ (external).
With a different device, use 4A0981Z (capacity), 4A0985Z (flow), 4A098DZ (resistance), 4A098LZ (volume) and 4A098MZ (total activity).
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.
