Arthroscopy and Minimally Invasive Joint Procedures
Arthroscopy basics
Arthroscopy codes are joint-specific and often compartment-specific. A diagnostic scope is included in any surgical arthroscopy of the same joint, so never report a diagnostic code with a surgical one. Knee examples: 29880 for medial and lateral meniscectomy, 29881 for one compartment, 29888 for ACL reconstruction, 29877 for chondroplasty. Shoulder examples: 29827 for rotator cuff repair, 29826 for subacromial decompression, 29824 for distal clavicle excision, 29807 for SLAP repair. Hip, ankle, elbow, and wrist each have their own code families.
Bundling and multiple procedures
Same-joint, same-session procedures often bundle. Chondroplasty is bundled into meniscectomy when performed in the same compartment; a separate compartment may justify modifier 59 or XS if documented. Subacromial decompression and rotator cuff repair have payer-specific rules, so check the current NCCI edit and the payer policy. Add-on codes must never be reported alone. When a scope converts to an open procedure, report the open procedure; the diagnostic scope is included.
Documentation traps
Limited debridement is not automatically a code. Identify the compartment, the structure treated, and whether the work was diagnostic or therapeutic. Laterality and joint must match the note.
Rule of thumb: one surgical arthroscopy code per joint unless a code is an add-on or a distinct, separately documented compartment is treated.
Worked example: Knee scope with medial and lateral meniscectomy plus chondroplasty of the patellofemoral compartment: report 29880 plus 29877 with modifier 59 only if the payer permits and the chondroplasty is in a separate compartment.
