Medical Billing Companies & Consultants in Corona, CA

Medical Lien Management Inc is a California revenue cycle and billing firm headquartered in Corona, in the Inland Empire. Its practice has its roots in 1989, and over more than three and a half decades it reports having worked with upward of 1,000 healthcare organizations statewide.

Clients range from individual practitioners to multi-specialty groups and hospitals, and the firm draws most of its identity from the payment channels that many practices find hardest to handle internally: California workers' compensation, personal injury liens and med-legal evaluations.

Services for California providers

Buyers will find a mix of conventional claims work and lien-specific legal support. The firm's published service lines include:

• Revenue cycle management covering the path from charge entry through final payment
• Medical billing and certified medical coding
• Workers' compensation billing aligned with California fee schedules
• Personal injury billing, lien tracking and post-settlement disbursement handling
• Med-legal billing for QME and AME evaluations and reports
• Denial management and the filing of appeals, including second bill reviews (SBR) and independent bill reviews (IBR)
• WCAB support, with representation at lien conferences, trials and settlements
• Accounts receivable management focused on aged balances

A notable differentiator is Jet Filing, an in-house electronic submission system the company uses for bulk lien and claim filing, which it credits with shorter turnaround and fewer errors. The firm also describes handling RFA submissions and scheduling, so a single vendor can cover intake, collections and the legal follow-up that disputed liens often require.

Specialties and client types

The company works across a broad set of disciplines, with particular depth in fields that generate comp and injury claims. Its site lists radiology and diagnostic imaging, electrodiagnostic medicine, psychology and clinical neuropsychology, psychiatry and neurology, chiropractic and acupuncture, interventional pain medicine, orthopaedic surgery, physical medicine and rehabilitation, occupational therapy and occupational medicine, and medlegal evaluators.

It also supports primary care settings such as internal medicine, family medicine, general practice, pediatrics, geriatrics and community health clinics, along with several surgical specialties. Recovery work extends to treatment, diagnostics, DME and rehabilitation collections.

How engagements work

New relationships typically start with a no-cost consultation in which the team reviews the practice's case mix and billing gaps; the firm also promotes a complimentary revenue cycle assessment. From there, its staff takes on intake and lien filing, prepares coded claims, monitors each claim, pursues appeals where payment is denied, and works aged accounts.

Clients are given ongoing status updates and injury reports through a central online platform, which the company presents as a key part of its emphasis on transparency.

On compliance, the firm states that its processes follow California Department of Industrial Relations rules, HIPAA and WCAB regulations, and it describes encrypted, audit-ready systems for patient data. Among its self-reported figures are more than 18.2 million original claims billed, roughly $6.8 billion recovered, a 29-day average turnaround and a 72 percent success rate on second reviews and appeals.

It has been featured in a Becker's Healthcare list of revenue cycle companies and recognized by DesignRush as a top BPO company for 2026. The company also produces a podcast, Workers' Comp Unwrapped, and a blog on billing and lien topics, which may appeal to practices wanting education alongside outsourced collections.

Revix MD provides outsourced medical billing and revenue cycle support to healthcare organizations nationwide, with its listed headquarters in Corona, California. Its client base spans independent physicians, group practices with several clinicians, newly launched offices, virtual care providers, federally qualified health centers, membership-based concierge practices, and hospitals and larger health systems. Riverside-area practices can hand over the entire payment cycle or bring the company in for narrower problems, such as overdue receivables or claims that are frequently rejected.

Services

Revix MD sorts its offerings into three groups: day-to-day billing, protection of incoming revenue, and coding, credentialing and administrative assistance. It frames its revenue cycle work as one coordinated workflow that follows a patient account from start to finish, beginning with coverage confirmation at registration and continuing through code assignment, claim filing, disputes and the final payment. Key offerings include:

• End-to-end billing and management of the full revenue cycle
• Pre-submission claim review that corrects mistakes before anything goes to the payer
• Confirmation of insurance coverage and plan benefits ahead of appointments
• Recording of payments and matching of electronic remittances and explanation-of-benefit statements
• Collection work on past-due accounts that have gone unpaid for some time
• Rejection prevention, payer disputes and follow-through, along with audits of captured charges
• Recovery of payments from non-contracted plans, processes aligned with the No Surprises Act, and patient billing statements
• Procedure, supply and diagnosis coding under CPT, HCPCS and ICD-10, as well as clinician credentialing and enrollment with insurers
• Work performed directly in the client's existing electronic health record, plus office operations assistance, advisory services, employee education and support with HIPAA obligations

Specialties and Payers

The company reports experience in over 25 fields of medicine and pairs each client with billing and coding staff familiar with the insurer requirements in that field. Its most prominently featured areas are pain management, internal medicine, gastroenterology, pulmonology, behavioral health and foot and ankle care.

Its broader list takes in heart care, brain and nervous system medicine, spinal and brain surgery, and psychiatric care, as well as kidney care, eye and vision exams, oral health practices, treatment of sleep disorders, care for infections and contagious illnesses, applied behavior analysis for autism, counseling and talk-based mental health services, addiction recovery programs, end-of-life and comfort care, and in-home medical services.

For insurers, it names specific support for Medicare, Medicaid plans run by individual states, Blue Cross Blue Shield, Aetna, Cigna, and claims involving workplace injuries.

How They Work With Clients

Before any agreement, Revix MD typically offers practices a no-cost review of their billing or revenue performance, and it also schedules product demonstrations. The firm says its goals are to raise the share of claims accepted on first submission, shorten how long accounts stay outstanding, and increase overall collections, while sparing practices the expense of staffing their own billing office.

Since its team can operate inside the electronic record system a practice already uses, no software switch is needed. Fees are set as a percentage of collections, and the company promotes support available at any hour.

Background

The company's history, as described on its site, starts with a niche billing team that grew into a revenue cycle partner for practices throughout the country. Revix MD characterizes its methods as compliant with HIPAA, centered on reducing rejected claims, and assisted by automated tools.

Among its leaders is Saqib Hassan, who serves as Vice President of Revenue Cycle Management and brings over a decade of background in billing, rejection handling and recovery of outstanding balances. The firm maintains billing resources tailored to individual states, California among them, and runs a blog covering news in the field.

Organizations evaluating billing partners may find the breadth of its specialty coverage and its insurer-focused programs helpful when deciding whether it suits their type of practice.
