Hey,
Your Dx is squamous cell cancer - back, so the code is 173.5. Now about 195.8 then plse refer following info regarding ur Dx & Neoplasm. (In this I specially point out the Skin & Cells involvment in both)
Squamous cell carcinoma (SCC) is a form of cancer of the carcinoma type that may occur in many different organs, including the skin, lips, mouth, esophagus, urinary bladder, prostate, lungs, vagina, and cervix. It is a malignant tumor of squamous epithelium (epithelium that shows squamous cell differentiation). Despite the common name, these are unique cancers with large differences in manifestation and prognosis.
Neoplasm is an abnormal mass of tissue as a result of neoplasia. Neoplasia (new growth in Greek) is the abnormal proliferation of cells. The growth of the cells exceeds, and is uncoordinated with that of the normal tissues around it. The growth persists in the same excessive manner even after cessation of the stimuli. It usually causes a lump or tumor. Neoplasms may be benign, pre-malignant or malignant.
In modern medicine, the term tumor is synonymous with a neoplasm that has formed a lump. In the past, the term tumor was used differently. Some neoplasms do not cause a lump.
A neoplasm can be benign, potentially malignant (pre-cancer), or malignant (cancer).
Hope this helps!
