What Services We Offer
Codex delivers a full spectrum of revenue cycle management services designed to optimize practice performance and financial health:

Medical Coding: Our certified medical coders review charts, validate ICD-10, CPT, and HCPCS accuracy, and ensure high clean-claims submission across a wide range of specialties such as cardiology, dermatology, mental health, neurology, physical therapy, plastic surgery, and more.

Medical Billing: Offering a true 24/5 service model, we process daily claims, manage both electronic and paper submissions, post payments, handle patient billing, follow up on outstanding claims, and resolve denials.

EMS Billing Services: Specialized EMS revenue support that includes payment posting, patient statements, credit card payments, denials, collections, and KPI-driven reporting tailored to emergency medical service providers.

Denial Management: Our dedicated team analyzes denial reasons, categorizes trends, performs payer follow-ups, and files appeals as needed. We emphasize eligibility checks, prior authorizations, coding precision, and medical necessity—leading to improved clean-claim rates.

Aging Accounts Receivable Recovery: Our AR specialists target aged insurance balances with tactical efforts to recover unpaid revenue. This service is also available a la carte to practices only needing advanced AR cleanup.

Credentialing & Contracting: Codex handles credentialing with payers, systematic follow-up until acceptance, and contracting support to secure favorable reimbursement terms.

Revenue Cycle Consulting: Our experts conduct in-depth billing reviews, identify workflow bottlenecks, audit financial performance, and recommend scalable improvements to boost revenue capture.
