Medical billing and coding jobs play a critical role in healthcare operations — going far beyond just doctors and nurses. There are professionals ensuring every medical service is documented, coded, and billed correctly. For every patient visit or treatment, and even for every insurance claim processed, skilled specialists handle these essential tasks. Without them, the healthcare system would be financially and administratively unsustainable.
As for anyone considering this profession, it might be interesting to know that there are varied medical billing and coding jobs, each differing in their own set of responsibilities, work environment, and earning potential. There are numerous options, whether they are entry-level or specialised coding positions, based on your individual interests, experience, and career objectives in this speciality.

The Rationale for Different Medical Billing and Coding Jobs
The responsibilities for medical billing and coding tasks need to be defined first.
- Medical Coding: Coders are responsible for translating healthcare services, diagnoses, and procedures into standardised codes (ICD-10, CPT, HCPCS). These coded elements are the primary components of the billing process.
- Medical Billing: Billers use those codes to create insurance claims and invoices, ensuring healthcare providers get paid appropriately.
Coders and billers are both crucial to healthcare administration. Whereas coders focus on accurate information, billers take care of the reimbursement. They help the healthcare system run smoothly and transparently from all reimbursement angles.
Entry-Level Medical Coding Roles for Beginners
When just starting out, the best way to get practical experience is through entry-level positions, which help you understand the interplay between coding and billing.
a. Medical Records Clerk
This is often the starting point for new entrants. Clerks organise patient records, verify documentation, and assist coders by ensuring medical files are accurate and complete.
Key Duties:
- Maintain records of patients and confidentiality
- Assist with data entry and organisation
- Support senior coders and billing staff
Ideal For:
Beginners seeking exposure to medical documentation before pursuing certification.
b. Junior Medical Coder / Trainee Coder
As a junior coder, you will be taught to assign basic diagnosis and procedure codes under supervision.
Key Duties:
- Enter patient data into coding software
- Review clinical documentation for accuracy
- Assist senior coders with audits and corrections
Requirements:
An introductory certificate in medical coding and knowledge of ICD-10 and CPT systems.
Career Progression:
After gaining a year of experience, junior coders typically move on to more advanced positions as a Certified Professional Coder (CPC) or as a Certified Coding Specialist (CCS).
c. Billing Assistant or Claims Processor
This position serves as an entry-level billing role revolving around claims preparation, payment posting, and data entry.
Key Duties:
- Input billing data from coded information
- Verify insurance details
- Prepare and submit basic claims
Skills Needed:
Attention to detail, good communication and familiarity with billing software.
Inpatient vs Outpatient Medical Coding Careers
One of the greatest differentiations within the industry is the separation of inpatient and outpatient coding. These categories identify how healthcare services are rendered and which services need to be delivered. Each requires different skills and certifications.
Inpatient Medical Coder
Inpatient coders are responsible for the coding of documentation of patients who are hospitalised and for whose stays exceed 24 hours. These patients’ records are more detailed and complex.
Responsibilities:
- Code diagnoses and procedures for long-term hospital stays
- Review surgical, laboratory, and radiology reports
- Apply ICD-10-CM and ICD-10-PCS codes
Required Skills:
Strong understanding of anatomy, physiology, and pathophysiology.
Analytical ability:
The ability to interpret and analyse extensive data around a patient.
Certification Recommended:
Certified Inpatient Coder (CIC) by AAPC or equivalent qualification.
Outpatient Medical Coder
Outpatient coders handle medical records for patients who receive short-term care at clinics, urgent care centres, and same-day surgery facilities.
Responsibilities:
- Assign CPT and ICD-10 codes for visits and minor procedures
- Ensure documentation supports the services billed
- Work closely with physicians to clarify unclear notes
Certification Recommended:
CPC (Certified Professional Coder) by AAPC.
Difference in Complexity:
Inpatient coding is more complex due to the analysis of multi-day treatments. Outpatient coding is more about speed and accuracy with the volume of work.
Specialized Medical Coding Jobs List
After gaining a few years of experience, coders often move into specialised areas. Specialisation not only improves accuracy in complex cases but can also significantly increase earning potential.
Here’s a breakdown of the most popular and highest paying medical coding specialties:
a. Emergency Department (ED) Coder
Coders in emergency care settings must quickly and accurately document varied cases — from trauma to minor injuries.
Why It’s Challenging:
The fast-paced nature of emergency medicine means incomplete or rushed documentation, requiring coders with excellent judgement.
b. Oncology Coder
Focuses on cancer diagnosis, chemotherapy, radiation, and oncology-specific treatments. This role requires advanced knowledge of complex treatment plans and drug codes.
Average Salary (UK): £35,000–£45,000
Certification: Certified Cancer Registrar (CTR) is highly valuable.
c. Radiology Coder
Specialises in imaging reports — X-rays, CT scans, MRIs, and ultrasounds.
Skills Required:
An eye for detail and familiarity with medical imaging terminology.
d. Surgery Coder
Surgical coding is among the most detailed areas, as it involves multiple procedures, modifiers, and compliance rules.
Why It’s High Paying:
Surgery coding demands advanced knowledge and precision, often paying higher salaries due to complexity.
e. Anaesthesia Coder
Involves coding anaesthesia services based on time units, modifiers, and medical necessity. Accuracy here directly affects insurance payments.
f. Cardiology Coder
Deals with heart-related procedures like angioplasty, ECGs, and cardiac surgery.
Highly technical, requiring strong understanding of cardiovascular anatomy and treatment codes.
g. Ophthalmology or Dermatology Coder
For those preferring outpatient and specialist clinic environments, these roles focus on visual or skin-related healthcare coding.
Why It’s Ideal for Beginners:
They’re relatively predictable and easier to code compared to surgical or oncology specialities.
