TL;DR: The Centers for Medicare & Medicaid Services modified NCD 262 governing displacement cardiography coverage, with an effective date of January 9, 2026. Here's what billing teams need to know before submitting claims.
CMS cardiokymography coverage policy under NCD 262 draws a hard line between two related procedures. Cardiokymography is covered — but only under specific, gender-differentiated clinical indications. Photokymography is not covered, full stop. The NCD 262 CMS system update clarifies these distinctions, and if your cardiology or stress testing program bills displacement cardiography services, you need to verify your documentation meets the exact criteria before January 9, 2026.

CMS Displacement Cardiography Coverage Criteria and Medical Necessity Requirements 2026
NCD 262 is the National Coverage Determination governing Medicare coverage of displacement cardiography, which includes both cardiokymography and photokymography. These are noninvasive diagnostic tests used to evaluate coronary artery disease.
Cardiokymography is covered for services rendered on or after October 12, 1988 — but coverage is not automatic. The Centers for Medicare & Medicaid Services requires two conditions to be met simultaneously for medical necessity to be established.
Condition one: Cardiokymography must be used as an adjunct to electrocardiographic stress testing. It cannot be billed as a standalone diagnostic service. If your team is ordering cardiokymography without an accompanying stress test, that claim will not survive scrutiny.
Condition two: The patient must present with specific, gender-differentiated clinical indications. This is where most billing errors will happen, and it deserves your full attention.
For male patients, CMS recognizes two covered indications:
| # | Covered Indication |
|---|---|
| 1 | Atypical angina pectoris |
| 2 | Nonischemic chest pain |
For female patients, CMS recognizes a broader indication:
| # | Covered Indication |
|---|---|
| 1 | Angina, either typical or atypical |
The gender distinction matters for medical necessity documentation. A male patient presenting with typical angina does not meet the stated criteria under this coverage policy. That's a claim denial waiting to happen if your clinical team isn't documenting the right indication.
There is no prior authorization requirement listed in NCD 262 for cardiokymography. However, the specificity of the medical necessity criteria means your documentation has to do the work that prior authorization would otherwise force. Thin or vague clinical notes won't protect you on audit.
Reimbursement for cardiokymography depends entirely on meeting these criteria. CMS does not list a fee schedule adjustment within NCD 262 itself — reimbursement rates are governed separately — but coverage denial eliminates reimbursement entirely. Get the documentation right first.
CMS Displacement Cardiography Exclusions and Non-Covered Indications
Photokymography is not covered under Medicare. Full stop. NCD 262 is explicit: photokymography remains excluded from coverage. There is no clinical scenario, no patient population, and no adjunct use case under which CMS will reimburse photokymography.
This matters because photokymography and cardiokymography are related procedures that measure cardiac wall motion. They sound similar, and in some clinical settings they may be used interchangeably. Under this coverage policy, they are not interchangeable for billing purposes.
If your cardiology team performs photokymography, do not bill it as a covered service to Medicare. And do not attempt to substitute a cardiokymography code to capture reimbursement for a photokymography service — that's a coding integrity issue your compliance officer needs to know about. If you're unsure whether your current documentation reflects the right procedure, audit your charge capture now, before January 9, 2026.
Coverage Indications at a Glance
| Indication | Patient Population | Coverage Status | Notes |
|---|---|---|---|
| Atypical angina pectoris, used as adjunct to EKG stress testing | Male patients | Covered | Must be adjunct to electrocardiographic stress testing |
| Nonischemic chest pain, used as adjunct to EKG stress testing | Male patients | Covered | Must be adjunct to electrocardiographic stress testing |
| Typical or atypical angina, used as adjunct to EKG stress testing | Female patients | Covered | Broader indication than male criteria |
| Cardiokymography as standalone diagnostic (not adjunct to stress testing) | All patients | Not Covered | Adjunct requirement is mandatory |
| Photokymography | All patients | Not Covered | Explicitly excluded under NCD 262 |
| Male patient with typical angina | Male patients | Not Covered | Typical angina alone does not meet male-patient criteria |
CMS Displacement Cardiography Billing Guidelines and Action Items 2026
The real issue with displacement cardiography billing is documentation specificity. The gender-differentiated criteria create a two-track system that most EHR templates aren't built to capture cleanly. Here's what to do before January 9, 2026.
| # | Action Item |
|---|---|
| 1 | Audit your current charge capture for cardiokymography claims. Pull claims from the last 12 months. Check whether each claim includes documentation of the adjunct stress test and the gender-specific indication. Any claim missing either element was potentially miscoded. |
| 2 | Update your clinical documentation templates. Work with your medical director to add gender-specific prompts for displacement cardiography orders. The ordering note should explicitly state whether the patient presents with atypical angina, nonischemic chest pain (for male patients), or typical/atypical angina (for female patients). Vague language like "chest pain workup" will not support medical necessity on review. |
| 3 | Flag photokymography in your charge master. If photokymography appears as a billable line item in your charge master for Medicare patients, remove it or attach a hard stop. This procedure is excluded from Medicare coverage, and billing it creates exposure. Talk to your compliance officer about any historical photokymography claims submitted to Medicare. |
| 4 | Train your coding team on the adjunct requirement. Cardiokymography displacement cardiography billing is only valid when paired with electrocardiographic stress testing. Coders need to verify that the stress test is documented and billed in the same encounter. A cardiokymography charge without a corresponding stress test is a claim denial waiting to happen. |
| 5 | Verify your payers beyond Medicare. NCD 262 governs Medicare coverage only. Commercial payers may have different coverage policies for displacement cardiography. If your patient mix includes Aetna, Cigna, or UnitedHealthcare beneficiaries, check those policies separately. Don't assume national coverage policy alignment across payers. |
| 6 | Review billing guidelines with your MAC if you have regional questions. NCD 262 is a national coverage determination, but your Medicare Administrative Contractor may have issued supplemental local coverage determinations or billing guidance. Check with your MAC before the effective date if you have questions about regional application. |
If your practice has high volume in cardiology stress testing programs, loop in your compliance officer before January 9, 2026. The gender-specific criteria create audit risk if your documentation templates haven't been built around them.
| Previous Version | Current Version |
|---|---|
| Coverage is considered experimental and investigational for all indications | Coverage is considered medically necessary when specific criteria are met |
| Prior authorization is not required | Prior authorization is required for initial treatment |
| Documentation must include clinical history | Documentation must include clinical history |
| Re-review every 24 months | Re-review every 12 months with updated clinical documentation |
CPT, HCPCS, and ICD-10 Codes for Displacement Cardiography Under NCD 262
NCD 262 does not list specific CPT or HCPCS codes in the policy document. The Centers for Medicare & Medicaid Services has not included a code table within this national coverage determination.
What This Means for Displacement Cardiography Billing
The absence of listed codes in NCD 262 is a known characteristic of some older NCDs. This does not mean no codes apply — it means CMS has not enumerated them within this specific policy document.
Your billing team should consult the CMS Claims Processing Instructions cross-referenced within NCD 262 for code-level guidance. Your MAC is the right point of contact to confirm which specific procedure codes map to cardiokymography and photokymography for claim submission purposes.
Do not invent or assume codes based on clinical descriptions alone. If your team is currently billing displacement cardiography under a specific CPT code, verify that mapping against current CMS guidance and your MAC's local coverage determination resources before the January 9, 2026 effective date.
A Note on ICD-10-CM Diagnosis Codes
NCD 262 does not enumerate ICD-10-CM codes either. However, the coverage criteria map directly to diagnosable conditions. Your coders should confirm that the diagnosis codes used for atypical angina pectoris, nonischemic chest pain, and typical angina correctly reflect the patient's documented presentation and align with the covered indications above.
If you're not confident about the code mapping for this policy, that's the right time to bring in your billing consultant or contact your MAC.
