US doctors and clinics get most of their money from insurance companies. Every patient visit has to become a correct insurance claim that is sent, tracked, paid, and chased if it's denied. That work is called medical billing, or revenue cycle management (RCM), and a lot of it is done by companies in Pakistan on US night shifts.
If you're detail-minded and comfortable speaking English on the phone, it's one of the steadiest remote career paths you can start without a medical degree.
What medical billers actually do
| Role | What you do all day |
|---|---|
| AR follow-up caller | Calls insurance companies about unpaid and denied claims |
| Eligibility verification | Checks each patient's insurance before their visit |
| Charge entry | Enters visits, codes and charges into the billing software |
| Payment poster | Records insurance and patient payments from payment reports |
| Denial management | Works out why claims were denied and fixes them |
Most people start in one of these roles at a billing company, then learn the rest of the cycle.
Do you need to be a coder or a doctor?
No. Medical coders assign codes from doctors' notes and usually need a coding certification. Medical billers work with claims, payments and insurers. Billers need to read codes (CPT for procedures, ICD-10 for diagnoses), not assign them from medical records.
The skills employers test
- The revenue cycle. From checking insurance before a visit to posting the final payment.
- Insurance terms. Deductible, copay, coinsurance, allowed amount and contractual adjustment.
- Denial reasons. Knowing why claims get denied, and what fixes each one.
- Phone English. AR callers spend the day on calls with US insurance representatives.
- HIPAA. The US patient privacy law. You must handle patient information safely, even from Pakistan.
Many companies give new hires a short test on terms and denials, a payment posting exercise, and, for calling roles, a mock insurance call.
HIPAA: the rule that matters most
Patient information is protected by law. Work only inside the employer's systems, never send patient details on WhatsApp or personal email, never take screenshots, and never paste patient data into AI tools. Employers ask about this in interviews, and one mistake can end a billing career.
Where to find medical billing jobs
- RCM and billing companies in Pakistan, especially in Lahore, Karachi, Islamabad and Faisalabad. Look on LinkedIn, Rozee.pk and company career pages.
- US billing companies hiring remote contractors, on LinkedIn and Upwork.
- Small US practices that need a part-time biller, once you have experience to show.
A first job at a Pakistani billing company is often the best start: paid training, real claims and real software. With a year or two of experience, freelance and direct US clients become much easier to win.
Certifications to aim for later
You don't need a certification for your first job. Once you're working, the AAPC's Certified Professional Biller (CPB) and the NHA's Certified Billing and Coding Specialist (CBCS) can raise your pay and help you win direct clients.
