CPT Code 29881: Knee Arthroscopy with Meniscectomy (Medial or Lateral)

Yes, CPT 29877 (chondroplasty) can be billed with 29881 only if performed in a different compartment of the knee joint. In such cases, modifier -59 or XS must be appended to indicate a distinct procedural service. If both procedures occur in the same compartment, 29877 is bundled and not separately billable.

If both the medial and lateral menisci are treated during the same arthroscopic procedure, report CPT 29880, not 29881. CPT 29881 covers either the medial or lateral meniscectomy, not both.

A minor synovectomy (limited removal of synovial tissue) is considered included in 29881. However, if a major or extensive synovectomy is performed and documented in a different compartment, you may report it separately using 29875 (limited) or 29876 (major), with modifier -59 if appropriate.
