Laboratory Testing for PFAS in Serum

We surveyed major companies that serve the Washington state health insurance market and learned most will cover the PFAS serum test when ordered by a clinician and processed by a clinical lab. See Survey results (PDF).  The most widely accepted insurance codes for the PFAS serum test are billing code CPT 82542 and diagnosis codes ICD-10 Z77.11 “Contact with and (suspected) exposure to environmental pollution” or ICD-10 Z77.111 “Contact with and (suspected) exposure to water pollution”.
