Malignant neoplasms overlapping site boundaries and the use of
subcategory.8 (overlapping lesion)
Categories C00-C75 classify primary malignant neoplasms according to their point of
origin. Many three-character categories are further divided into named parts or
subcategories of the organ in question. A neoplasm that overlaps two or more contiguous
sites within a three- character category and whose point of origin cannot be determined
should be classified to the subcategory.8 ("overlapping lesion"), unless the
combination is specifically indexed elsewhere. For example, carcinoma of oesophagus and
stomach is specifically indexed to C16.0 (cardia), while carcinoma of the tip and ventral
surface of the tongue should be assigned to C02.8. On the other hand, carcinoma of the tip
of the tongue extending to involve the ventral surface should be coded to C02.1 as the
point of origin, the tip, is known. "Overlapping" implies that the sites
involved are contiguous (next to each other). Numerically consecutive subcategories are
frequently anatomically contiguous, but this is not invariably so (e.g. bladder C67.-) and
the coder may need to consult anatomical texts to determine the topographical
Sometimes a neoplasm overlaps the boundaries of three-character categories within certain
systems. To take care of this the following subcategories have been designated:
恶性肿瘤的位置重叠 , 以及次类别 .8 ( 重叠性病灶 )
C00-C75 类别是根据原发部位来归类原发性恶性肿瘤 ,
, 在叁码分类内一个肿瘤如果跨越一个以上相邻部
位且原发部位不明者可归类於次分类 . 8 , 此重叠区
已在其他地方有特殊归类则不在此限。例如 : 食道
和胃癌是明示在 C16.0 ( 贲门部 ) , 而舌尖和舌腹面癌
, 被定为 C02.8 , 当原发部位已知为舌尖 , 舌尖癌扩展
至舌腹面 , 必须登录为 C02.1 , 重叠性意为侵犯的部位
是连接的 ( 至另一邻近部位 ) 而连续的数字类别在
解剖学上常常是连续的 , 这是会变化的 ( 如 : 膀胱 (
C67.- ) ) 登录者需要查解剖书来决定局部解剖的关系

在一些系统里有时肿瘤在叁特质类别范围有重叠 ,
为了收录这些特性而有下列的次类别命名 :

Dissociative anaesthesia and sensory loss
Anaesthetic areas of skin often have boundaries that make it clear that they are
associated with the patient's ideas about bodily functions, rather than medical knowledge.
There may be differential loss between the sensory modalities which cannot be due to a
neurological lesion. Sensory loss may be accompanied by complaints of paraesthesia. Loss
of vision and hearing are rarely total in dissociative disorders.
Psychogenic deafness
麻痹的皮肤区域反应出病人对身体功能的观念 , 而
