ICD-10 and Radiation Oncology Steven M. Verno, CEMCS September 23, 2008 Note: ICD-9-CM and ICD-10 are owned and copyrighted by the World Health Organization. The codes in this guide were obtained from the US Department of Health and Human Services, NCHS website. For at least the past twenty (20) + years, we have learned and used ICD-9-CM when coding for our providers. As someone once said, just when we learned the answers, they changed the questions. Also, for years, there has been rumor that ICD-10 would be replacing ICD-9, and now this will soon be a reality. According to the Code of Federal Regulations, specifically, 45 CFR Parts 160 and 162, Titled HIPAA Administrative Simplification: Modification to Medical Data Code Set Standards To Adopt ICD 10 CM and ICD 10 PCS; Proposed Rule, dated August 22, 2008: We propose October 1, 2011 as the compliance date for ICD 10 CM and ICD 10 PCS code sets for all covered entities. It is important to note that the compliance date must occur on October 1 in order to coincide with the effective date of annual Medicare inpatient PPS updates. There is an old saying in coding, If it isn t documented, it doesn t exist or it didn t happen. When ICD- 10 becomes effective, it s success is dependent on the provider s documentation. If the documentation shows, OM, many of us know this means Otitis Media. Under ICD-9-CM, you have the following codes for OM: ICD-10 will require more work on the provider to document the exact type of diagnosis found with the patient. ICD-10 opens more with the anatomical area affected and allows for coding of chronic modalities. Lets look at some of the most used codes in the Radiation Oncology with the ICD-10-CM Instructions Note: Functional activity All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm. Morphology [Histology]

Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, etc. The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma, the morphology (histologic type) is included in the category and codes. To identify the morphology for the majority of Chapter 2 codes that do not include the histologic type, comprehensive separate morphology codes are provided. These morphology codes are derived from the second edition of the International Classification of Diseases for Oncology (ICD-O). The correct morphology code can be found in the Alphabetic Index to Diseases under the main and subterm term for the type of neoplasm, adenocarcinoma, sarcoma, etc. Primary malignant neoplasms overlapping site boundaries A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code.8 ("overlapping lesion"), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned. Malignant neoplasm of ectopic tissue Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).
