What this service is designed to deliver when deployed inside your workflow.
Medical Coding Outsourcing for UK Companies.
Claim denials are costing you 5–10% of revenue because coding accuracy can't keep up with volume. Deploy AAPC-credentialed medical coders from Nairobi — ICD-10, CPT, and OPCS-4 proficient — from £10,200 per coder per year.

Overview
What is Medical Coding?
Medical coding outsourcing involves deploying credentialed coders to translate clinical documentation into standardised codes — ICD-10-CM/PCS, CPT, HCPCS, and OPCS-4 — for billing, reimbursement, and regulatory reporting. Treba's medical coders in Nairobi hold AAPC or AHIMA credentials and work inside your coding platform via secure VDI, ensuring no patient data is stored locally.
Typical client
UK private healthcare providers, NHS-contracted services, medical billing companies, and health-tech platforms that need to scale coding capacity without the 6-month recruitment timeline for qualified UK coders

The challenge
Why UK companies struggle with medical coding.
Medical coding is a bottleneck that directly impacts revenue. Every incorrectly coded claim is either denied or underpaid. UK healthcare providers report first-pass denial rates of 8–12%, and most denials trace back to coding errors — wrong ICD-10 code, missing modifier, unsupported diagnosis-procedure link. Qualified medical coders are scarce in the UK market. AAPC-credentialed coders command £30,000–£40,000, and demand consistently outstrips supply. The alternative — training general admin staff to code — produces error rates that cost more in denied claims than the salary savings. Meanwhile, coding backlogs grow: clinical documentation sits for 5–10 days before coding, cash collection cycles extend, and revenue recognition lags behind actual service delivery.

“I code 80–100 encounters per day across cardiology and orthopaedics for a UK private hospital group. My first-pass accuracy rate is 97.2%. When I see a discharge summary, I understand the clinical reasoning behind the procedures — not just the documentation. That is why my denial rate is 1.8% against a 9% department average before I started.”
