Medical Biller

Position Overview

We are seeking a knowledgeable and detail-oriented Medical Biller with hands-on experience in payment posting and accounts receivable (A/R) follow-up. This role will support our revenue cycle operations remotely, ensuring claims are processed accurately, payments are posted correctly, and outstanding balances are pursued with diligence.

Training will be provided for our specific workflows and systems. We are looking for someone who does not just absorb training — but actively documents it. The ideal candidate will create clear, organized Standard Operating Procedures (SOPs) throughout the onboarding process, building a lasting knowledge base that supports the team long-term.

Experience with Practice Fusion, Availity, and Greenway is highly preferred.

Key Responsibilities

Payment Posting

• Post patient payments accurately to the correct accounts, charges, and service dates

• Identify and post contractual adjustments, write-offs, and denied amounts in accordance with payer contracts

• Reconcile daily payment batches and ensure all postings balance to deposits

• Flag discrepancies, underpayments, and zero-pay remittances for A/R review and follow-up

Accounts Receivable (A/R) Follow-Up

• Work assigned A/R queues to follow up on outstanding claims with insurance payers and patients

• Investigate and resolve unpaid, denied, or underpaid claims by contacting payers via phone or payer portals

• Identify denial trends and root causes, escalating systemic issues to the billing manager

• Resubmit corrected claims, submit appeals, and provide supporting documentation as required

• Monitor claim aging reports and prioritize follow-up based on payer deadlines and dollar amounts

• Maintain accurate and up-to-date notes on all account activity within the billing system

SOP Development & Documentation

• Actively document workflows, processes, and system steps throughout the training period to create comprehensive SOPs

• Write clear, step-by-step procedures that can be used for future onboarding, cross-training, and quality control

• Organize and maintain the SOP library, updating documentation as workflows evolve or system changes occur

• Proactively identify gaps in existing documentation and flag processes that need to be captured or clarified

Note: SOP creation is a core expectation of this role from day one of training — not an afterthought.

General Billing Operations

• Assist with eligibility verification and benefits checks as needed

• Support month-end billing reconciliation and reporting

• Stay current on payer-specific billing requirements, coding updates, and compliance guidelines

Required Qualifications

• Demonstrated experience in medical billing with a focus on payment posting and A/R follow-up

• Strong working knowledge of the medical billing cycle from claim submission through payment reconciliation

• Experience working with EOBs, ERAs, and payer denial codes

• Ability to create clear, organized Standard Operating Procedures — this is a key deliverable of this role

• Strong attention to detail and accuracy in all data entry and financial posting

• Comfortable working independently and managing a billing workload remotely

• Professional written and verbal communication skills

• Experience with Availity — claims submission, eligibility, and payer portal management

• Experience with Greenway Health — practice management and billing workflows

• Familiarity with ICD-10, CPT, and HCPCS coding as it relates to claim accuracy
