What is the CPT code for diagnostic arthroscopy of the left knee with medial meniscectomy?

• A. 29881
• B. 37609
• C. 31276
• D. 69421

Answer: (A)

The chosen answer, which is the CPT code 29881, is accurate for diagnostic arthroscopy of the left knee accompanied by a medial meniscectomy. This code specifically describes the combination of a diagnostic procedure using arthroscopy to visualize the knee joint and the surgical procedure where a portion of the medial meniscus is removed due to damage or tears.

CPT code 29881 is defined in the context of orthopedic procedures, particularly for the knee, where the primary focus is on both the assessment and treatment of knee joint issues. This code captures the complete process — starting with the diagnostic aspect of arthroscopy and including the therapeutic component of the meniscectomy.

Reasons for the inaccuracy of the other choices involve their specific applications: 37609 pertains to different vascular procedures, 31276 relates to nasal endoscopy, and 69421 is for tympanostomy procedures related to ear surgery. None of these codes align with the procedures involved in knee arthroscopy or meniscectomy. Thus, 29881 is the correct and specific code for the described procedures associated with the left knee.
