The Challenge

A cardiology group came to Aethera with a 14.2% denial rate — driven almost entirely by cardiac catheterization modifier errors and bundling issues on stress testing codes. Their AR had ballooned to 47 days, and a recent billing staff departure left a three-month gap in denial follow-up. An estimated $40,000/month was being written off without appeal.

The Solution

Aethera assigned a dedicated cardiology coding team that rebuilt their modifier matrix for the entire 93000-series. We implemented real-time eligibility checks pre-appointment and created a payer-specific rules library covering their top 8 payers. The backlog of unappealed denials was worked through systematically over 60 days.

"We were writing off $40,000 a month in denials we assumed were uncollectable. Aethera recovered most of it in the first 60 days — and then made sure it wouldn't happen again."

Admin Burden

The Challenge

A family medicine practice had been relying on front desk staff to handle billing alongside scheduling and patient intake. Their clean claim rate was 78% — 17 points below industry standard — and there was no systematic denial follow-up. A coding audit revealed consistent undercoding on complex office visits: 99214s being submitted as 99213s, 99215s as 99214s.

The Solution

Aethera took over the complete billing function and ran a 90-day coding audit that identified the undercoding pattern across 8 months of historical claims. We rebuilt the physician's E&M documentation templates, educated the provider on MDM-based coding, and implemented a denial tracking dashboard in the provider portal.

"I was essentially giving away $200,000 a year because my front desk was coding every visit at the same level. I had no idea until Aethera showed me the data."

The Challenge

An orthopedic practice with high implant volume was experiencing significant revenue leakage from two sources: inconsistent implant cost capture (missing invoice-level documentation for implants billed under C-codes and L-codes) and repeated global period violations triggering payer audits. Their AR stood at 52 days, and they had received two payer audit letters in 18 months.

The Solution

Aethera built a procedure-specific charge capture checklist that required implant invoice reconciliation before claim submission. A global period tracking module was implemented in their PM system, flagging any claims that risked modifier conflicts. The audit response team handled both pending audit letters, resulting in no recoupment.

"The implant billing alone paid for Aethera's fees ten times over in the first year. And the audit letters stopped completely."

The Challenge

A dermatology practice with high Mohs surgery volume had been miscoding Mohs staging procedures for years — submitting single-stage codes without the required block and specimen-count add-ons. Additionally, reconstructive cases were being written off because documentation didn't meet medical necessity standards for their top two payers. Their denial rate was 18%.

The Solution

Aethera assigned a Mohs-specialist coder who rebuilt the practice's procedure coding from the ground up. We created documentation templates specifically designed to satisfy reconstructive necessity criteria for each of their top payers. A payer-specific Mohs rule library was maintained and updated quarterly.

"We'd been coding Mohs the same way for seven years and nobody told us it was wrong. Aethera fixed it in 30 days and we haven't had a Mohs denial since."

Net Revenue

The Challenge

A behavioral health group was struggling on three fronts: E&M and psychotherapy claims were triggering bundling edits on major payers, prior authorization denials for newer psychiatric medications were running at 34%, and patient collections were functionally nonexistent — balances were either written off or sent to collections with no intermediate step.

The Solution

Aethera restructured the group's claim submission logic to properly unbundle therapy and medication management per payer policy. A prior auth workflow was built specifically for the psychiatry formulary, with escalation paths for denials. A four-step patient statement series with a soft-touch phone follow-up protocol was implemented for all patient balances over $50.

"We weren't collecting from patients at all — we'd write it off rather than have an uncomfortable conversation. Aethera built a system that collects professionally without damaging the therapeutic relationship."

Cash Flow Gap

Major concern

None

The Challenge

An internal medicine group was transitioning from hospital-employed billing to independent billing following an ownership change. They had no existing billing infrastructure, providers who needed credentialing with their new TIN, and a hard go-live date 45 days out. Cash flow continuity was the primary concern.

The Solution

Aethera executed a full build-out of the billing infrastructure: credentialing for all providers simultaneously, eClinicalWorks integration configuration, fee schedule loading, and payer enrollment. Claims began processing on day 38 — two days ahead of the hard deadline. A dedicated project manager coordinated across all workstreams.

"Aethera built our entire billing operation from scratch in under 6 weeks. Every provider was credentialed, the system was live, and we didn't miss a single payment cycle."
