CMS Modified NCD 68 for Hemodialysis as Schizophrenia Treatment — What Billing Teams Need to Know in 2026

TL;DR: The Centers for Medicare & Medicaid Services modified NCD 68, which governs hemodialysis as a treatment for schizophrenia, with an effective date of January 9, 2026. The policy continues to deny Medicare coverage for this service. No specific CPT or HCPCS codes are listed in the policy document.

NCD 68 in the Medicare system is a National Coverage Determination with a clear position: hemodialysis for schizophrenia treatment is not covered. The Centers for Medicare & Medicaid Services cites inconclusive scientific evidence as the basis for the non-coverage decision. This modification doesn't open a door — it confirms the door stays shut.

Quick-Reference Table

CMS Hemodialysis for Schizophrenia Coverage Criteria and Medical Necessity Requirements 2026

The CMS hemodialysis schizophrenia coverage policy under NCD 68 rests on one core determination: the scientific evidence is inconclusive. That's the exact language in the policy. Medicare does not consider hemodialysis a medically necessary treatment for schizophrenia, and this modification does nothing to change that standing.

Medical necessity is the central issue here. CMS applies a strict evidentiary standard when evaluating whether a service qualifies for reimbursement under Medicare. Hemodialysis hasn't cleared that bar for schizophrenia, and the updated NCD 68 reaffirms that position.

If a provider submits a claim for hemodialysis with a primary or principal diagnosis of schizophrenia, Medicare will deny it. There is no clinical scenario described in the policy where this service becomes covered under this diagnosis. The coverage policy is a flat denial.

That matters for your billing team because some staff may assume "modified" means expanded. It doesn't. A policy modification can mean minor administrative cleanup, language clarification, or structural reformatting within the CMS policy framework — not a change to the underlying coverage decision.

CMS Hemodialysis for Schizophrenia Exclusions and Non-Covered Indications

The entire premise of NCD 68 is a non-covered indication. Hemodialysis billed for the treatment of schizophrenia does not qualify for Medicare reimbursement. Full stop.

The policy's benefit category is Physicians' Services — so this NCD applies broadly across the Medicare program, not just to specific facility types. Whether a claim comes from a hospital outpatient department, a freestanding dialysis center, or a physician billing for oversight of dialysis, the non-coverage determination follows the diagnosis, not the setting.

CMS calls out the evidence standard directly: "scientific evidence supporting use of hemodialysis as a safe and effective means of treatment for schizophrenia is inconclusive at this time." That phrase "at this time" leaves theoretical room for a future coverage reversal if the evidence base changes. But there's no indication CMS is reconsidering. Don't build a billing strategy around that qualifier.

CMS Hemodialysis Billing Guidelines and Action Items 2026

The real issue with a policy like this isn't the coverage decision itself — everyone in nephrology and psychiatric billing already knows hemodialysis isn't a psychiatric treatment. The risk is edge cases: complex patients with both end-stage renal disease and a schizophrenia diagnosis, where a coder uses the wrong primary diagnosis on a claim.

These action items are specific to that risk.

If you treat a significant volume of ESRD patients who also carry psychiatric diagnoses, loop in your compliance officer before the effective date. The risk isn't intentional billing for hemodialysis as a schizophrenia treatment — it's a sequencing error on a complex claim that lands in the wrong denial bucket.

CPT, HCPCS, and ICD-10 Codes for Hemodialysis Under NCD 68

No Codes Listed in NCD 68

The NCD 68 policy document does not include any CPT, HCPCS, or ICD-10 codes. This is not unusual for older National Coverage Determinations — some NCDs predate the current coding structure and were written as categorical coverage decisions rather than code-level policy.

For hemodialysis billing guidelines tied to specific procedure codes, your Medicare Administrative Contractor's Local Coverage Determinations are the right reference point. LCDs and billing guidelines from your MAC govern the code-level requirements for covered hemodialysis claims. Do not rely on NCD 68 for code-level guidance — it doesn't provide it.

The non-coverage determination in NCD 68 applies when the clinical intent of the hemodialysis service is treatment of schizophrenia — regardless of which procedure code appears on the claim.

The Bigger Picture on NCD 68

This policy is a legacy non-coverage determination. The January 9, 2026 modification is documented in the CMS coverage database. The non-coverage decision itself remains intact.

What the source policy does not describe is the nature of the change — whether it reflects a substantive clinical review or an administrative update. If you need to understand exactly what changed between versions, check the CMS coverage database directly or contact your MAC.

Medical necessity didn't change. Reimbursement didn't change. What changed is the version date. Track it accordingly.
