Rheumatology / infusion coding consultant wanted

[f.leffler@brixahealth.com]

Hi all — I'm with Brixa Health, an early-stage company building AI denial-management and appeal automation for rheumatology practices and infusion centers. We're looking for a certified coder to do a short paid engagement (roughly 10–20 hours to start, possible ongoing advisory work) reviewing our denial logic against how payers actually behave in the real world.

What you'd be doing:

• Sanity-checking our CARC/RARC mappings for medical-benefit biologic denials — which code combinations UHC, Aetna, Cigna and others actually emit for step-therapy, PA, and benefit-exclusion denials
• Reviewing our appeal-deadline tables for those payers
• Looking at synthetic 835/ERA test files and telling us whether they look like the remittances you've actually worked
• Weighing in on rheum infusion specifics: J-codes for adalimumab/infliximab/abatacept (incl. biosimilars), JW/JZ modifiers, units, common payer edits

Important: this is all synthetic test data — no PHI, no BAA, no patient records. You can start right away. It's a subject-matter-expert role, not production coding.

Looking for: current CPC (AAPC) or CCS, 3+ years in rheum/infusion or another buy-and-bill specialty, real hands-on denials/appeals experience with provider-administered drugs, and fluency reading 835s and CARC/RARC codes. Direct UHC/Aetna/Cigna experience is a big plus. Rate is $60+/hr depending on experience. Fully remote, flexible hours.

If Interested, please email me at f.leffler@brixahealth.
