McKesson Health Solutions now has a new program called CPHM which combines both CPUR and CPUM. The Interqual training is not included in the certification, it is seperate. I enrolled in the CPUR independent study program and took a proctored exam at the local library (it was easy). See what the UR jobs in your area require, some states you have to have this certification. I would obtain the CPHM and just take the test. I wouldnt worry about Interqual, it is self explanatory and can be learned without the training. Basically the book is broken down by level of care and body systems and you apply the clinical criteria.
