Cigna Healthcare Medicare Advantage update: Incorrect coding for dialysis services

September 17, 2024

We routinely review our coverage, reimbursement, and administrative policies for potential updates. In that review, we take into consideration one or more of the following: evidence-based medicine, professional society recommendations, Centers for Medicare & Medicaid Services (CMS) guidance, industry standards, and our other existing policies.

As a result of a recent review, effective for dates of service on or after September 27, 2024, Current Procedural Terminology (CPT®) codes 90935 and 90937 will be administratively denied when billed in an outpatient setting with an end-stage renal disease (ERSD) diagnosis. These CPT codes are used for inpatient ESRD and non-ESRD procedures, or for outpatient non-ESRD dialysis services.

This update aligns with the national coding and payment standards set by CMS. Additional information is available in the Medicare Claims Processing Manual > Chapter 8 – Outpatient ESRD Hospital, Independent Facility, and Physician/Supplier Claims > Section 170 > Subsection B.
