Medicare is proposing to add new payment codes for unattended sleep testing, also known as home sleep apnea testing (HSAT). The American Academy of Sleep Medicine (AASM) announced that the Centers for Medicare & Medicaid Services (CMS) has included these new Current Procedural Terminology (CPT) codes in its proposed rule for the 2025 physician fee schedule. According to the AASM, the codes could help more Medicare beneficiaries access sleep disorder diagnosis without the need for an in-lab sleep study.

Key Takeaways

  • CMS has proposed new CPT codes for unattended sleep testing in its 2025 proposed rule.
  • The codes are intended for home sleep apnea tests (HSAT) used to diagnose sleep disorders.
  • The AASM supports the inclusion, which may improve access to sleep testing for Medicare beneficiaries.
  • The proposed rule is open for public comment before finalization.

What Are the New CPT Codes for Unattended Sleep Testing?

The new CPT codes describe unattended sleep testing, which is typically performed in a patient’s home rather than a sleep lab. According to the AASM announcement, the codes cover a range of home sleep apnea tests, including devices that measure airflow, respiratory effort, and oxygen saturation. The proposed rule includes codes for both simple and comprehensive unattended sleep studies, as well as a code for the interpretation and report of the results.

These codes are distinct from the existing codes for in-lab polysomnography. The AASM has been advocating for specific CPT codes for home sleep tests to ensure appropriate reimbursement and to encourage greater use of this convenient diagnostic option.

Why Does This Matter for Sleep Apnea Diagnosis?

Sleep apnea affects millions of Americans, and many remain undiagnosed. In-lab sleep studies are the gold standard, but they can be expensive, inconvenient, and difficult to schedule. Home sleep apnea tests offer a simpler, more accessible alternative for many patients. By establishing dedicated CPT codes, CMS signals that unattended sleep testing is a recognized and reimbursable service.

The AASM noted that the new codes could remove barriers to diagnosis. Medicare beneficiaries often face restrictions on where and how they can receive sleep testing. The proposed codes may help standardize coverage and reduce out-of-pocket costs for patients who qualify for home testing.

What Is the CMS Proposed Rule?

Each year, CMS releases a proposed rule that outlines changes to the Medicare physician fee schedule and other payment policies. The rule includes updates to CPT codes, reimbursement rates, and coverage policies. The 2025 proposed rule, which includes the new unattended sleep testing codes, is open for public comment. Stakeholders such as the AASM, healthcare providers, and patient groups can submit feedback before CMS finalizes the rule later this year.

The inclusion of these codes in the proposed rule does not guarantee final adoption. CMS may modify or remove codes based on public comments and further analysis. The AASM indicated it will continue to work with CMS to ensure the codes are appropriate and beneficial for patients.

How Will This Affect Patients and Providers?

If the codes are finalized, providers who perform and interpret home sleep apnea tests will have specific billing codes for those services. This could simplify the billing process and reduce denials. For patients, the new codes may lead to broader Medicare coverage of home sleep testing, meaning fewer trips to a sleep lab and lower costs.

However, the AASM cautioned that coverage decisions also depend on local Medicare administrative contractors. The new codes create a framework, but not every Medicare beneficiary will automatically qualify for home testing. Physicians will still need to follow medical necessity guidelines.

Next Steps for the Proposed Rule

The public comment period for the 2025 proposed rule is open until early September 2024. The AASM plans to submit formal comments supporting the new codes. Stakeholders can also submit individual comments. After reviewing input, CMS will issue a final rule, typically in November, with changes taking effect on January 1, 2025.

The AASM emphasized that the inclusion of these codes is a positive step, but ongoing advocacy is needed to ensure that home sleep testing is accessible and adequately reimbursed.

Frequently Asked Questions

What is unattended sleep testing?

Unattended sleep testing, also called home sleep apnea testing, is a diagnostic sleep study that a patient performs at home without a sleep technician present. It typically uses portable devices to measure breathing, oxygen levels, and heart rate during sleep. It is used primarily to diagnose obstructive sleep apnea.

Will Medicare cover home sleep tests under the new codes?

If the proposed CPT codes are finalized, Medicare will have specific payment codes for unattended sleep testing. However, coverage will still depend on medical necessity, provider qualifications, and local Medicare policies. The codes are a step toward more consistent coverage, but not an automatic guarantee for all patients.

When will the new CPT codes take effect?

The new codes are in the CMS proposed rule for the 2025 physician fee schedule. If finalized, they would take effect on January 1, 2025. The public comment period and final rule process will determine whether the codes are adopted as proposed or modified.
