About 09DM4ZZ

09DM4ZZ is the ICD-10-PCS code for a extraction procedure on the nasal septum using a percutaneous endoscopic approach. In ICD-10-PCS, extraction means pulling or stripping out or off all or a portion of a body part by the use of force.

In plain terms, this corresponds to other operations on nose, the ICD-9-CM procedure title it maps to (21.99).

For a different body part, codes include 09D74ZZ (right tympanic membrane), 09D84ZZ (left tympanic membrane), 09DB4ZZ (right mastoid sinus), 09DC4ZZ (left mastoid sinus), 09DL4ZZ (nasal turbinate), 09DP4ZZ (accessory sinus) and 8 more.

The same procedure with a different approach is coded 09DM0ZZ (open) and 09DM3ZZ (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC), DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

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