Client Overview

A Multi-Specialty Group Facing OON Reimbursement Challenges

Xecta Technologies partnered with a multi-specialty physician group operating across two states to evaluate ongoing Out-of-Network reimbursement challenges impacting cash flow, denial rates, and payer recovery performance.

The organization had multiple providers and service locations spread across two states, each with varying payer participation statuses. The engagement focused on strengthening payer workflows, improving compliant OON reimbursement recovery, and reducing preventable revenue leakage across multiple specialties and service lines.

Commercial payer relationships with BCBS, Aetna, Cigna, and UnitedHealthcare were evaluated across all service lines to identify inconsistencies in billing workflows, documentation standards, and denial patterns that were suppressing reimbursement performance.

The physician group required a structured, compliance-driven approach — one that addressed both the immediate revenue recovery opportunity and the long-term operational improvements needed for sustainable OON billing performance.

The Problem

Operational & Reimbursement Gaps Identified

Following a comprehensive revenue cycle assessment, six key operational and reimbursement gaps were identified that were directly contributing to suppressed OON collections and compliance exposure.

  • Unrecognized OON Status: Multiple providers and service locations had active OON status with several commercial payers — unknown to the organization — resulting in inconsistent reimbursement outcomes.

  • 📋

    Insufficient Documentation Workflows: Many OON claims lacked supporting documentation and standardized workflows for medical necessity review, contributing to reimbursement reductions and avoidable denials.

  • 📅

    Limited Appeal Infrastructure: Minimal appeal processes were in place, causing denied or underpaid claims to age beyond payer reconsideration timelines — permanently forfeiting recoverable revenue.

  • 🔗

    Coding & Modifier Inconsistencies: Modifier usage, diagnosis-to-procedure linkage, and claim editing varied across urgent care, radiology, physiotherapy, podiatry, and wound care — triggering automated payer edits and denials.

  • 🚫

    NSA Compliance Exposure: Front-end workflows for patient financial communication and OON disclosure documentation were inconsistent, creating potential compliance exposure under the No Surprises Act.

  • 💰

    No Payer Escalation Strategy: The organization had not pursued structured payer escalation workflows or single-case agreement negotiations for higher-cost specialty services, leaving significant revenue unrecovered.

The Approach

Six-Phase OON Billing & Recovery Strategy

A dedicated task force consisting of certified coders (CPC), billing specialists (CPB), and payer relations professionals implemented a structured six-phase optimization program tailored to the organization's specialty mix and payer environment.

1

OON Audit & Claims Assessment

Performed a detailed review of outstanding OON accounts receivable, underpayments, denial patterns, aging reports, and reimbursement trends across all commercial payers.

2

Payer Contract & Regulatory Review

Reviewed payer participation status, continuity-of-care provisions, network gap considerations, and applicable federal and state OON reimbursement regulations.

3

Claims Correction & Resubmission

Corrected claim edits, coding inconsistencies, modifier application issues, and clinical documentation deficiencies prior to resubmission across all affected specialties.

4

Appeals & Reconsideration Management

Implemented first-level and second-level appeal workflows supported by medical necessity documentation, EOB analysis, and payer-specific reimbursement review.

5

Payer Negotiation & Escalation

Coordinated payer discussions for eligible single-case agreements (SCAs) and escalated unresolved disputes through appropriate regulatory and payer review channels.

6

Compliance & Staff Training

Provided operational training for front-end and billing staff regarding compliant OON disclosure workflows, documentation standards, and No Surprises Act requirements.
