Which of the following lesions is raised with a diameter of more than 5 mm?

In dermatology, a nodule is classified as a solid lesion that is raised and has a diameter exceeding 5 mm. This characteristic is essential for distinguishing nodules from other types of skin lesions. While papules are also raised lesions, they typically measure less than 5 mm in diameter. Macules are flat and not raised at all, presenting as discolored patches on the skin, while scales are not lesions but rather a buildup of keratinocytes on the skin surface that can accompany various skin conditions.

The defining feature of a nodule is its size and solidity, making it palpable under the skin, which is essential for correct identification and classification in medical coding. Understanding these distinctions is crucial for accurate documentation and coding of skin lesions in practice.
