Medical coding forms an important part of medical billing services for a number of reasons:

Standardized Communication: Medical codes offer common language for the communication of medical diagnoses and procedures, thereby ensuring that healthcare providers and insurance companies clearly know the exact services rendered.
Correct Claim Submission: Accurate coding ensures claims are submitted using the correct codes, which optimizes the chances of appropriate reimbursement in a timely manner.
Denials Reduced: Proper coding minimizes the chances of denial on account of coding errors at the initiative level, thus saving a lot of time and resources that a medical billing specialist would use in follow-up of such claims.

It can make appropriate medical billing service, proper remuneration, effective financial management, decisions based on data, and compliance. It is, therefore, an indispensable part of the healthcare system in presenting quality care to the healthcare provider with financial sustainability.
