LOCATION: Outpatient, Hospital PATIENT: Beth Mahoney PRIMARY CARE PHYSICIAN: Ronald Green, MD SURGEON: Mohomad Almaz, MD PREOPERATIVE DIAGNOSES 1. Chondromalacia, left knee. 2. Torn left medial meniscus per MRI scan. POSTOPERATIVE DIAGNOSIS: Chondromalacia, left knee. PROCEDURES PERFORMED 1. Examination, left knee, under anesthesia. 2. Arthroscopy, left knee, with debridement of chondromalacia. ANESTHESIA: General with endotracheal intubation. FINDINGS: The patient was found to have significant chondromalacia in all three compartments. She had some bare bone on the femoral trochlear and significant fraying of the articular cartilage on the patella, as well as on the medial femoral condyle. The articular cartilage on the lateral femoral condyle was just frayed slightly, but no large flaps of articular cartilage were raised. She did, however, have some flaps of articular cartilage raised on the floor of the lateral compartment. I could not find any specific meniscal tears, but both medial and lateral menisci had fringe tags, which we removed. The anterior cruciate ligament was intact. PROCEDURE: Under general anesthesia the patient’s left knee was examined. She had no effusion. The collateral ligaments were intact. Lachman test was negative, as was the pivot shift. McMurray test was negative. We then prepped the patient’s left leg with Betadine and draped it in a sterile fashion. An Esmarch bandage was used to exsanguinate the leg, and a tourniquet on the thigh was inflated to 300 mm Hg. The total tourniquet time was about 35 minutes. Three portals were used for this procedure. The first was placed along the superior anterolateral aspect of the knee, the second was placed along the inferior anterolateral aspect, and the third along the inferior anteromedial aspect of the knee. We distended the knee with lactated Ringer’s solution. We examined the suprapatellar pouch and the medial and lateral gutters. We immediately noted significant chondromalacia involving the patellofemoral joint. There were large flaps of articular cartilage hanging off the articular surface of the patella and actually an area of bare bone on the trochlea, which was close to the lateral femoral condyle. We used the shaver to trim the articular cartilage, which was hanging from the subchondral bone. We trimmed the leading edge of the fat pad slightly as well. I then examined the medial compartment and probed the medial meniscus. We could not identify a specific tear of the medial meniscus, although there were multiple fringe tags, which were removed with the shaver. She does have, however, significant chondromalacia involving the weight-bearing surface of the medial femoral condyle. There were flaps of articular cartilage that were loose and just laying on the subchondral surface. We used the shaver to trim these loose bits of articular cartilage. We then examined the notch area and probed the anterior cruciate ligament. It was intact. We then examined the lateral compartment and probed the lateral meniscus. The lateral meniscus was intact, although there were several fringe tags, which were removed. She did have some raised flaps of articular cartilage on the lateral tibial plateau, and these were trimmed with the shaver. The articular cartilage in the lateral femoral condyle appeared to be in relatively good condition with only minor fraying. At this point, we thoroughly irrigated the knee and looked for any remaining loose fragments. We then drained the knee and injected 80 mg of Depo-Medrol with 2 cc of 1% Xylocaine. The hardware was removed and the skin incisions were closed using 4– 0 nylon suture. Sterile dressings were applied under a 6-inch Ace wrap. She was then awakened and taken from the operating room in good condition, breathing spontaneously. FINAL SPONGE AND NEEDLE COUNT: Correct. MEDICATIONS: She was given IV Kefzol preoperatively, and she will be continued on Keflex for 5 days postoperatively as well. She will also be started on some aspirin postoperatively. Pathology Report Later Indicated: Chondromalacia. Abstracting & Coding Questions: 1. Was this a diagnostic or surgical arthroscopy? 2. What is chondromalacia? 3. Debridement of the chondromalacia is also referred to as 4. Was the diagnosis for the meniscal tear reported? 5. What CPT code(s) would be reported for this case? 6. What ICD-10-CM code(s) would be reported for this case?

What ICD-10-CM code(s) would be reported for this case?Explanation / Answer
1. It is a surgical Arthroscopy ,which is done to diagnose the problems in the knee joint. In this procedure ,the surgeon makes a small incision and inserts a small camera which is called arthroscope to visualise the knee joint and ligents and according to which the repair is done.
2. Chrondromalacia is the inflammation of undersurface of patella . It results from degeneration of and softening of the cartilage underlying the patella . It is also known as runner's knee. It is most common in sports person and older people due to overuse and having diseases like arthritis.
3. Debridement of the chondromalacia is also referred to as patellar debridement because it involves the underlying cartilage of patella.
4.As per the preoperative MRI there was a diagnosis of left medial meniscul tear reported ,but during the procedure the surgeon could not find any specific meniscal tears,but both the medial and lateral menisci had fringe tags which were removed.
5. CPT code is current procedural terminology. It is a medical c code used to report medical, surgical, diagnostic procedures and services to entities such as physicians , insurance company etc. The CPT code for this case depends upon the shaving done whether it is in the same compartment or different compartment of the knee, does it involves any loose body etc. 29877,29880 and HCPCS -G0289 are the codes .
29877 is for - Arthroscopy,knee, surgical debridement/shaving of articular cartilage.
29880 is for - Arthroscopy , knee, surgical with meniscectomy (medial and lateral) including meniscal shaving.
HCPCS code- G0289 is used when there is - Arthroscopy, knee, surgical removal of loose body debridement of articular cartilage at the time of other surgical knee arthroscopy in a different compartment of same knee.
5. ICD -10 - CM code for left knee chondromalacia is M22.42,which can be used to indicate diagnosis in areas where diagnosis is mentioned in the form of ICD-10-CM code.
