Summary

Beginning January 15, 2026, CareSource will enhance claims editing for lymphedema compression treatment items (HCPCS codes A6520-A6610) to require appropriate lymphedema diagnosis codes and mandatory RT/LT modifiers to indicate treatment side (right or left). Bilateral billing is now permitted with proper modifier usage.

Action Required

Action needed
By January 15, 2026: Billing team must update claims submission processes and billing software to enforce the following requirements for all lymphedema compression treatment item claims (codes A6520-A6610): (1) Validate that claims include appropriate lymphedema diagnosis codes before submission; (2) Require RT (right) or LT (left) modifiers on all claims to indicate treatment laterality; (3) Enable bilateral claim processing to allow both sides to be billed on the same claim with appropriate modifiers. Update encounter forms and billing templates to prompt providers to specify diagnosis and treatment side. Train billing staff on the new modifier requirements. Verify that your billing system can accommodate bilateral claims with laterality modifiers. Failure to include required diagnosis codes and modifiers will result in claim denials or rejections during CareSource's enhanced editing process.
