About 08NPXZZ
08NPXZZ is the ICD-10-PCS code for a release procedure on the left upper eyelid using an external approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.
In plain terms, this corresponds to Canthotomy, the ICD-9-CM procedure title it maps to (08.51).
For a different body part, codes include 08N0XZZ (right eye), 08N1XZZ (left eye), 08N6XZZ (right sclera), 08N7XZZ (left sclera), 08N8XZZ (right cornea), 08N9XZZ (left cornea) and 5 more.
The same procedure with a different approach is coded 08NP0ZZ (open) and 08NP3ZZ (percutaneous).
It is an operating-room procedure in the MS-DRG logic for DRG 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), DRG 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator), DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), DRG 115 (Extraocular Procedures Except Orbit), DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC) and DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Extraocular Procedures Except Orbit”, “Other Skin, Subcutaneous Tissue and Breast Procedures” and 2 more.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
