Regulators
California Department of Public Health (CDPH), Laboratory Field Services, handles state laboratory credentials. The Centers for Medicare & Medicaid Services (CMS) administers the federal Clinical Laboratory Improvement Amendments (CLIA) program. CDPH laboratory facilities · CMS CLIA.
Applications and changes
State license or registration submissions, CMS-116 certification applications, ownership changes and laboratory-director updates. We identify the credentials appropriate to the test complexity and operation. CDPH CLIA application guidance.
Commercial and survey work
Reference-laboratory agreements, specimen-processing responsibilities, result delivery, audit cooperation and responses to deficiency findings. We connect the service commitments with the legal and operational responsibilities they create.
Testing scope
California registration for waived or provider-performed microscopy testing is distinct from licensure for more complex testing. We assess a proposed test-menu change before assuming the current credential covers it. CDPH facility categories.
Collection versus testing
A collection-only location presents a different CLIA question from a site performing tests. We review what happens at each location and any separate state requirements. CMS CLIA starting guidance.
Service arrangements
Collection-site agreements, logistics and courier contracts, staffing, record access and responsibility for rejected or compromised specimens.
For testing within a walk-in clinic, see Urgent Care.
Equipment and professional oversight
CDPH's Radiologic Health Branch regulates radiation-related activities, including X-ray-machine registration and relevant professional permissions. We assess the modality and services; CLIA is a laboratory-testing framework, not a general imaging license. CDPH Radiologic Health Branch.
Applications and changes
Radiation-machine registration and ownership or equipment changes, including RH 2261N or RH 2261C where appropriate. We connect the submission with the equipment purchase, lease and operating entities. CDPH registration process.
Provider arrangements
Radiologist agreements, equipment and space leases, image access, professional interpretation and billing responsibilities. Medicare independent diagnostic testing facility enrollment is a separate question where the IDTF model applies. CMS enrollment manual, section 10.2.2.4.
Yes. Share the current services, credentials, proposed addition and related agreements. We identify the legal questions and distinguish them from clinical validation or technical certification work.
Yes. Send the finding or contract and any deadline. We can define the response work and its fixed fee without requiring a broader engagement.
