About 0SRC0LA
0SRC0LA is the ICD-10-PCS code for a replacement procedure on the right knee joint using an open approach with synthetic substitute, unicondylar medial (qualifier: uncemented). 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 total knee replacement, the ICD-9-CM procedure title it maps to (81.54).
For a different body part, codes include 0SRD0LA (left knee joint).
With a different device, use 0SRC06A (synthetic substitute, oxidized zirconium on polyethylene), 0SRC0JA (synthetic substitute), 0SRC0MA (synthetic substitute, unicondylar lateral) and 0SRC0NA (synthetic substitute, patellofemoral).
It is an operating-room procedure in the MS-DRG logic for DRG 461 (Bilateral or Multiple Major Joint Procedures of Lower Extremity with MCC), DRG 462 (Bilateral or Multiple Major Joint Procedures of Lower Extremity without MCC), DRG 469 (Major Hip and Knee Joint Replacement or Reattachment of Lower Extremity with MCC or Total Ankle Replacement), DRG 470 (Major Hip and Knee Joint Replacement or Reattachment of Lower Extremity without MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC) and DRG 908 (Other O.R. Procedures for Injuries with CC), under the surgical categories “Bilateral or Multiple Major Joint Procedures of Lower Extremity”, “Major Hip and Knee Joint Replacement or Reattachment of Lower Extremity or Total Ankle Replacement”, “Other O.R. Procedures for Injuries” and 1 more.
It was added in FY2017, effective October 1, 2016.
