Medicare Update: Beneficiaries Just Got New Lab Payment Rates

Key Points:

• CMS released preliminary 2027 payment rates for clinical lab services, based on private insurer data under PAMA, showing Medicare pays about 16% more than private insurers for lab tests and projecting $1 billion in annual taxpayer savings.
• The largest proposed payment reductions are in genomic sequencing (-23%), molecular pathology (-22%), microbiology (-19.3%), and immunology (-19.3%), with routine chemistry tests seeing an average 16% reduction; cuts will be phased in gradually due to legal limits.
• While out-of-pocket costs for Medicare beneficiaries likely won’t change immediately, lab groups warn that reimbursement cuts could threaten patient access, especially in rural and underserved areas.
• Industry leaders like Quest Diagnostics criticize the PAMA methodology as flawed and advocate for legislative reform via the RESULTS Act, supported by numerous lawmakers and healthcare organizations.
• CMS is accepting public comments for 30 days before finalizing rates in November, with concerns that continued payment reductions may lead to more restrictive Medicare practices and impact lab service availability.
