Understanding Aetna incident-to billing for mental health practices

Posted by 49 minutes ago (https://mentalhealthbilling.us/understanding-aetna-incident-to-billing-for-mental-health-practices/)

Description: Aetna incident-to billing for mental health involves an important distinction often overlooked in billing guides: Aetna’s behavioral health supervisory billing policy is separate from Medicare’s incident-to billing requirements. Using the terms interchangeably can cause a practice to apply the wrong requirements.

How to appeal a denied psychotherapy claim: A step-by-step guide

Posted by 23 hours ago (https://mentalhealthbilling.us/how-to-appeal-a-denied-psychotherapy-claim-a-step-by-step-guide/)

Description: A psychotherapy claim denial requires a specific response. Missing authorization, incorrect billing information, and a disputed medical necessity decision each call for different evidence. Sending the same appeal letter for every denial leaves the payer’s actual objection unanswered. To appeal a denied psychotherapy claim, identify the reason, confirm the applicable deadline, and connect your supporting records to the disputed requirement. Before filing an appeal, first determine whether the claim should be corrected instead. This guide explains how healthcare providers and medical billing students can review a denial, assemble an appropriate appeal, and track the decision through payment or further review.

Humana Medicare Advantage Coding, Claims Billing, and Denial Management

Posted by 3 days ago (https://a2zbillings.com/humana-medicare-advantage-coding-claims-billing-and-denial-management/)

Description: Humana Medicare Advantage billing seems deceptively simple until the first stack of denials lands on your desk. On paper, it's Medicare. In practice, it's a separate payer with its own portal, prior authorization list, appeal clock, and audit machinery. Practices that treat it like traditional Medicare with a different card leak revenue every month, and most never trace the leak back to its source. This guide shows where the money gets lost and how to stop it. That’s from the billers at A2Z Billings, a team with 150+ years of combined experience and a 98% first-pass clean claim rate. We have dealt with the odd denial, slow remit, and audit letter so you don't have to.

Description: If you've ever had a clean-looking psychotherapy claim bounce back for no obvious reason, there's a decent chance a missing or misapplied credential modifier was the culprit. The HO modifier is one of the quieter troublemakers in behavioral health billing small, easy to overlook, and capable of stalling reimbursement for weeks when it's handled wrong.

Mental Health Billing Psychotherapy CPT Codes 2026

Posted by 26 days ago (https://mentalhealthbilling.us/cpt-code-99404-billing-description-time-reimbursement-cigna-eap-guide-2026/)

Description: CPT code 99404 is a 60-minute preventive medicine counseling code, but behavioral health billing teams often encounter it for a very different reason: Cigna uses 99404 as the required claims code for many Employee Assistance Program (EAP) sessions. That creates confusion because the code's standard CPT meaning is preventive counseling for a patient without a related illness, while Cigna's EAP use is an administrative claims-routing rule. Understanding that distinction is important for accurate coding, authorization, reimbursement, and denial prevention.
