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.
