New ICD 10 codes RDN use for reimbursement
October 2024 Blog
October 1, 2024, there were significant additions, revisions and deletions to ICD 10 codes RDNs use for reimbursement. These categories affected were codes used for Type 1 diabetes, hypoglycemia, obesity, adults, teens and children and disordered eating.
The referring provider will select the appropriate code(s) for the MNT referral as RDNs cannot diagnose. It behooves RDNs and their billing department(s) to be aware of the new codes, as well as to confirm which are billable and not, prior to submitting a claim or providing a superbill.
The following are several of the new codes:
1. Presymptomatic Type 1 Diabetes
E10.A0 Type 1 diabetes mellitus, presymptomatic, unspecified

dysglycemia
