The knee joint consists of three primary compartments:
1. Medial compartment: The inside part of the knee, which includes the femur and tibia interaction on the inner side.
2. Lateral compartment: The outside part of the knee, where the femur and tibia meet on the outer side.
3. Patellofemoral compartment: The area between the patella (kneecap) and the femur.
These three compartments are essential for knee joint stability and function, allowing movement and weight- bearing activities.
B: Trochlea groove and vestibular are not associated with knee anatomy.
C: Posterior malleolus, scapula, and fibular facet do not relate to knee compartments; the malleolus is in the ankle, scapula in the shoulder, and fibular facet is not part of the primary knee compartments.
D: Cochlea is unrelated to knee anatomy and refers to a part of the inner ear.
Thus, the correct answer is A. Medial, lateral, and patellofemoral.

Modifier 53 is used to report a discontinued procedure. It indicates that a procedure was started but terminated due to the patient's well-being being at risk. In this scenario, the percutaneous transluminal coronary angioplasty was attempted but stopped because of an anatomical problem that created a risk for the patient, preventing the completion of the procedure.References: AMA's CPT Professional Edition, coding guidelines on the use of modifiers.

For the injections, CPT code 64642 is used for chemodenervation of one extremity; 64643 for each additional extremity, and 64647 for chemodenervation of muscles in the paraspinal region. The modifier -50 is added to 64642 and 64643 to indicate bilateral procedures. According to CPT guidelines, when multiple sites are treated, each site is coded separately, and appropriate modifiers are used.

The described scope reaches thesigmoid colon, which is consistent with aflexible sigmoidoscopyrather than a full colonoscopy. The key therapeutic action is that the polyps were treated byablation(destruction), not snare excision or biopsy. CPT45346represents flexible sigmoidoscopy withablationof tumor(s), polyp(s), or other lesion(s). You report the sigmoidoscopy ablation codeoncefor the session; you do not multiply it by the number of polyps unless CPT instructions explicitly direct unit reporting (which is not the standard approach for these endoscopic therapeutic codes). For diagnosis, polyps in thesigmoid colonare coded asK63.5 (polyp of colon).K62.1is arectal polypcode and does not fit because the polyps are in the sigmoid colon. Therefore,
45346withK63.5is correct. CPC exam tip: match thescope extent(sigmoid) and theremoval method(ablation).
