ICD9 Billing Codes for
EIN Diagnoses
Accurate diagnostic codes
are essential for reimbursement of pathology services, and the most commonly
employed system is the ICD-9-CM curated by the ICD-9-CM Coordination and
Maintenance Committee and issued by the Dept. of Health and Human Services of
the US government. Effective October 1, 2009
two new ICD-9
diagnostic codes were issued, for benign endometrial hyperplasia and EIN as
defined in the pathology literature (ref 1,2). These can be referenced for
diagnostic pathology services in which EIN or benign endometrial hyperplasia is
diagnosed.
