In a letter to US Representative Diane Black and other sponsors, Jay R. Lieberman, MD, AAHKS President, expresses support for H. R. 2247, the “Increasing Clarity for Doctors by Transitioning Effectively Now Act” (“ICD-TEN Act”). Due to the exponential increase in the number of codes in the new ICD-10 coding system and the complexity of the sub-coding framework, CMS should conduct full end-to-end testing and ensure that the claims processing system is fully functioning before implementation. Dr. Lieberman has also asked for an 18-month “safe harbor transitional period” that would protect Medicare claims that might be denied solely due to coding errors. Read the letter.
