Purpose

Two jobs in one revenue cycle — not two salary cards.

Last reviewed: 2026-04-25.

Medical billing turns coded encounters and coverage data into claims, payments, remittances, and follow-up. AAPC describes it as generating healthcare claims and submitting them to insurers for payment.

Medical coding translates documentation into ICD-10-CM/PCS, CPT, and HCPCS codes. Coding accuracy upstream reduces denials and rework for billers.

This page does not invent separate billing vs coding pay ladders. For published wages, use the wage guide (BLS SOC 29-2072). For a full credential catalog, use certification programs.

Workflow

Where each role sits in the claim path

Coding creates claim language from documentation; billing drives payment and follow-up.

Dimension	Medical billing	Medical coding
Primary input	Coded encounter, demographics, coverage, payer rules	Clinical documentation, operative notes, test results
Primary output	Clean claim, payment posting, denial follow-up, patient balance	ICD-10-CM/PCS, CPT, HCPCS code assignment
Main question	How do we get this claim paid correctly?	What happened clinically, in standard codes?
Closest entry credential	AAPC CPB (Certified Professional Biller)	AAPC CPC or AHIMA CCA

Credentials

Closest-credential mapping

For billing-first careers, AAPC’s CPB (Certified Professional Biller) is the most direct fit; CPC and AHIMA CCA expand mobility into coding and broader health information roles. Confirm current fees and CEU rules on the issuer site before you enroll.

Billing-first

Closest entry fit: AAPC CPB. Also common: Some employers accept CPC or local certificates for combined roles.

Coding-first

Closest entry fit: AAPC CPC or AHIMA CCA. Also common: AHIMA CCS for inpatient / advanced coding tracks.

Broader HIM / records

Closest entry fit: AHIMA RHIT (education-dependent). Also common: Confirm degree and eligibility rules on AHIMA.
