Diseases and Disorders of the Eye

Surgical hierarchy

In the order the grouper applies them, highest first. A patient with several procedures is assigned to the highest surgical class one of them belongs to, so this ordering decides the DRG, not the order procedures appear on the claim.

1. 1 Orbital Procedures
   • 113 Orbital Procedures with CC/MCC 2.1287
   • 114 Orbital Procedures without CC/MCC 1.2658
2. 2 Extraocular Procedures Except Orbit
   • 115 Extraocular Procedures Except Orbit 1.4797
3. 3 Intraocular Procedures
   • 116 Intraocular Procedures with CC/MCC 1.6273
   • 117 Intraocular Procedures without CC/MCC 1.0620
