About 4A1D8BZ

4A1D8BZ is the ICD-10-PCS code for a monitoring procedure on the urinary using a via natural or artificial opening endoscopic approach with pressure. In ICD-10-PCS, monitoring means determining the level of a physiological or physical function repetitively over a period of time.

In plain terms, this corresponds to urinary manometry, Cystometrogram and urethral pressure profile [UPP], the ICD-9-CM procedure titles it maps to (89.21, 89.22 and 89.25).

For a different body part, codes include 4A168BZ (lymphatic), 4A1B8BZ (gastrointestinal) and 4A1J8BZ (products of conception, nervous).

The same procedure with a different approach is coded 4A1D7BZ (via natural or artificial opening).

With a different device, use 4A1D83Z (contractility), 4A1D85Z (flow), 4A1D8DZ (resistance) and 4A1D8LZ (volume).

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

It was added in FY2018, effective October 1, 2017.
