Question

I need help coding a medical report: Operative procedure- After suitable general anesthesia had been acheived, patient's right knee was prepped and draped in usual manner. Befor prepping, a thigh tourniquet was applied; after draping, it was inflated to 300 mm Hg. No inflow cannula was used, Arthroscope was inserted through anteromedial portal. The lateral compartment was examined. Everything looked good. Examination of the notch revealed some inflated synovial tissue, which was cauterized with radiofrequency probe. Examination of the medial compartment revealed a horizontal cleavage tear and flap tear of the posterior horn of the medial meniscus. Using a combination of punch and shaver , the unstable meniscus was excised and contoured. The tibial surfaces revealed a small area of water by the anterior horn of the meniscus. Femoral surfaces showed diffuse wear of grade 3 occasional areas of grade 4 chondromalacia from 0 to 90 degrees. Examination of the patellofemoral joint revealed very good looking articular surfaces on the inferior half of the patella in the trochlea. However there were essentially bare bone on the superior half of the articular surface. The knee joint was then thoroughly irrigated, and the arthroscope removed. Stab wounds were closed with 3-0 nylon. A dressing was then applied. Tourniquet was released, after which good circulation was noted to return to the foot. The patient tolerated the procedure well and returned to recovery in stable condition

Answer 1

CPT code:
Right Knee Arthroscopy - 29881 RT
RT is right side
HCPCS code (health care common procedure coding system)
Arthroplasty knee, surgical, lateral, medial or patellar compartments - G0289 RT
General Anesthesia:
special Anesthesia code should be coded separately. Anesthesia procedure done by the anesthetist separately, it should be coded as 99100.
