Summary

New Jersey Medicaid (NJ FamilyCare) established billing procedures for COVID-19 testing claims using HCPCS code U0002 (effective April 1, 2020 for independent labs; February 4, 2020 for CDC tests). Providers must use specific ICD-10-CM diagnosis codes when submitting COVID-19-related claims, with different codes required for confirmed cases, exposures, and suspected cases with symptoms.

Action Required

Action needed
Immediately: Billing team must update claims submission procedures for all NJ FamilyCare COVID-19 testing claims. (1) For independent laboratories: Begin using HCPCS code U0002 via HIPAA 5010 or Direct Data Entry (DDE) for non-CDC tests. For hospital labs: Temporarily use revenue code 229 with procedure code U0002 until July 1, 2020 (expect updated guidance by then). (2) Billing team must implement ICD-10-CM coding requirements in billing system: use B97.29 ONLY for confirmed COVID-19 cases with specific symptom codes (J12.89, J20.8, J40, J22, J98.8, J80); use Z03.818 for ruled-out exposures; use Z20.828 for actual COVID-19 exposure; use symptom codes (R05, R06.02, R50.9) for suspected cases without definitive diagnosis. Do NOT assign B34.2 or B97.29 for suspected/probable COVID-19. Providers and billing staff must apply these coding rules immediately to all new COVID-19 claims. Failure to use correct procedure and diagnosis codes will result in claim denials from NJ FamilyCare.
