ICD-10 Code Set Info

The ICD-10-CM code set replaced the ICD-9-CM code set on October 1, 2015, for covered entities under the Health Insurance Portability and Accountability Act (HIPAA). ICD-10-CM uses different formatting and an expanded character set.

Labcorp provides ICD-10 coding resources that may be helpful for your office.

Labcorp continues to rely on the ordering physician to provide diagnostic information for the individual patient. In accordance with HIPAA standards, Labcorp requires a valid diagnosis at the highest level of specificity in order to bill third-party payers, including Medicare and Medicaid. Missing diagnoses, diagnosis codes lacking the highest level of specificity, and nonspecific narratives all require follow-up with the ordering physician or his/her authorized designee for clarification. Providing a formatted ICD-10-CM code at the time of order will minimize letters and/or calls.

ICD-10 Tools Available from Leading Coding Organization

There are many resources available from coding organizations that may work for your practice. Some of the resources that Labcorp has found to be most helpful and reliable with ICD-9 and ICD-10 crosswalk are from American Academy of Professional Coders (AAPC). An ICD-10 code conversion tool and ICD-9 to ICD-10 crosswalk documents are available from the AAPC for more than 15 medical specialties.

AAPC is the country’s largest coding training and credentialing organization for the business side of health care. Their certified members in medical coding, medical billing, medical auditing, compliance, and practice management represent the highest level of expertise in the industry. Through training, resources and support provided by AAPC, thousands of organizations and professionals have learned how to appropriately use the ICD-10 coding set.

AAPC offers lists of crosswalks for the top 50 ICD-9 codes to corresponding ICD-10 codes for many specialties, including but not limited to, cardiology, dermatology, family practice, gastroenterology, internal medicine, OB/GYN, and urology.
