About 09RM0KZ
09RM0KZ is the ICD-10-PCS code for a replacement procedure on the nasal septum using an open approach with nonautologous tissue substitute. In ICD-10-PCS, replacement means putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part.
In plain terms, this corresponds to other septoplasty, the ICD-9-CM procedure title it maps to (21.88).
For a different body part, codes include 09R00KZ (right external ear), 09R10KZ (left external ear), 09R20KZ (bilateral external ear), 09R50KZ (right middle ear), 09R60KZ (left middle ear), 09R70KZ (right tympanic membrane) and 8 more.
The same procedure with a different approach is coded 09RM3KZ (percutaneous) and 09RM4KZ (percutaneous endoscopic).
With a different device, use 09RM07Z (autologous tissue substitute) and 09RM0JZ (synthetic substitute).
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 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC) and DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other Musculoskeletal System and Connective Tissue O.R. Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures” and 2 more.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
