About D9199CZ

D9199CZ is the ICD-10-PCS code for a brachytherapy procedure on the soft palate using a high dose rate (HDR) approach with californium 252 (cf-252) (qualifier: none).

In plain terms, this corresponds to Radioisotopic teleradiotherapy, the ICD-9-CM procedure title it maps to (92.23).

For a different body part, codes include D9109CZ (ear), D9119CZ (nose), D9139CZ (hypopharynx), D9149CZ (mouth), D9159CZ (tongue), D9169CZ (salivary glands) and 5 more.

The same procedure with a different approach is coded D919BCZ (low dose rate (LDR)).

With a different device, use D91997Z (cesium 137 (cs-137)), D91998Z (iridium 192 (ir-192)), D91999Z (iodine 125 (I-125)), D9199BZ (palladium 103 (pd-103)) and D9199YZ (other isotope).

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.
