2.Provide at least two examples of issues with mapping from one coding classification version to another version.

3.Articulate the role of Health Information Management professionals in this type of data analytics process.

Answer 1

1. mapping ICD 9CM code 960 to ICD10CM -This is the code used for Poisoning and adverse effects and it usually uses two codes Diagnostic and External cause code 960-979 and 980-989.But in ICD10AM both these codes are captured into single oneT36-T50 for drugs and T51-T65 for toxic effects.
2. ICD Codes is an integral part of medical billing Therefore a coder must be fluent in both the ICDs'.Crosswalking is the term used for mapping.ICD9CM is being transitioned to ICD10 CM since new diseases are discovered .The latter caps about 13000 codes while the former about 68000.It is a very difficult task and requires amiable vital skills. One of the major difficulty is that,since ICD 10CM has much morecodes compared to ICD9CM,discrepancies can occur and it is the duty of the coder to sort out the difficulties.
3. Only a few percentages of codes of both ICD10CM andICD9CM matches well,while the other portion will not directly matchEg ICD9CM code 416.0(pulmonary hypertension) and the ICD 10CM code 1270(primary pulmonary hypertension)    Approximate matches with multiple choices put the coders to select the best from a number of same choices,different diagnoses may fall under one set.ICD10CM codesC220(Liver cell carcinoma) and C22(Hepatoblastoma both corresponds to ICD 9CM code 155.0(malignant neoplasm of the liver,primary).
4. HIM (Health Information Management) has now extended their role from handling ,storing and retrieving information to making decision.With the changing roles and novel challenges ,HIM professionals should always be vigilant in their work process.They need to develop newer skills and develop strategies to overcome challenges in thefield.
