At a special angle known as Brewster's angle, no p-polarized light is reflected from the surface, thus all reflected light must be s-polarized, with an electric field perpendicular to the plane of incidence. A simple linear polarizer can be made by tilting a stack of glass plates at Brewster's angle to the beam.
In this particular instance, we would start off by measuring the wound in the length dimension. Where there is the maximum length of this wound of approximately 5.7 centimeters. The width would then be measured at its maximum point of width which is 2.5 centimeters. The depth we then would determine by probing the wound with our cotton-tipped applicator using the cotton end.
Measure Margins, Wound Area. When a provider performs lesion removal, he will remove the lesions as well as margins of healthy tissue around the wound. For your lesion removal claims, you need to add the dimensions of the lesion your provider removes to the margins, and then use that length to determine code choice. Example: The physician removes a 0.9 cm benign lesion from a patientâs left leg with a 0.4 cm margin. This means that total excision size was 1.3 cm. On the claim, you would report 11402 (Excision, benign lesion including margins, except skin tag [unless listed elsewhere], trunk, arms or legs; excised diameter 1.1 to 2.0 cm) for the removal.
