How to Read a Medical Record for Coding

 Reading a medical record accurately is a critical skill for medical coders. The goal is to extract essential information and translate it into standardized codes for diagnoses, procedures, and services. A medical coder must be both detail-oriented and knowledgeable about medical terminology, anatomy, and coding guidelines.

1. Understand the Structure of a Medical Record

Medical records follow a standard format, often divided into sections such as:

Patient Demographics: Name, age, gender, insurance.

History and Physical (H&P): Patient's medical history, complaints, and examination.

Progress Notes: Ongoing updates from physicians or nurses.

Consultation Reports: Specialist evaluations.

Operative Reports: Details of surgical procedures.

Discharge Summary: Final diagnoses and treatment summary.

Knowing where to find information helps streamline the coding process.

2. Identify Key Diagnoses and Procedures

Coders must focus on the chief complaint, primary diagnosis, and procedures performed. Look for the “Assessment” and “Plan” sections in SOAP (Subjective, Objective, Assessment, Plan) notes, which often contain the final diagnosis.

For procedures, refer to the operative report, which describes what was done, the technique, and any complications.

3. Look for Supporting Documentation

Always verify that documentation supports the codes. For example, if a physician lists “Type 2 Diabetes,” ensure there are related notes, lab results, or medications that confirm it.

Review for:

Lab and Imaging Results

Medications Prescribed

Follow-up Plans

These details validate the diagnosis and guide accurate code assignment.

4. Apply Official Coding Guidelines

After identifying the relevant data, use coding manuals like:

ICD-10-CM: For diagnosis codes

CPT: For procedures and services

HCPCS Level II: For medical equipment or supplies

Always apply the official guidelines and check for modifiers, sequencing rules, and payer-specific requirements.

5. Watch for Common Pitfalls

Don’t code “rule out” or suspected conditions as confirmed.

Ensure the documentation is complete and legible.

Avoid assumptions—only code what’s clearly stated and supported.

Reading a medical record for coding is a skill developed with practice and precision. By understanding the structure, identifying key information, and applying coding rules correctly, medical coders ensure accurate documentation, compliance, and proper reimbursement. Whether you're coding inpatient charts or outpatient visits, attention to detail is your greatest tool.
