How Medical Coders Read Patient Charts

What Is a Patient Chart?

A patient chart is a collection of healthcare information documenting a patient's medical care. It may contain details such as diagnoses, symptoms, procedures, medications, test results, physician notes, and treatment information.

For a Medical Coder, reading patient charts carefully is an essential skill. Coders use documented information to assign appropriate standardized codes according to applicable coding guidelines. They do not diagnose patients or make clinical assumptions.

Why Do Medical Coders Read Patient Charts?

The primary purpose of reviewing a patient chart is to understand what has been documented and determine which conditions, procedures, and services may require coding.

Accurate chart review helps medical coders:

• Identify documented diagnoses
• Understand procedures and services
• Select appropriate ICD-10-CM codes
• Assign applicable CPT codes
• Identify relevant HCPCS Level II codes
• Check documentation for coding requirements
• Follow coding guidelines
• Avoid unsupported assumptions

Step 1: Review Patient Information

A coder begins by reviewing basic information available in the record, such as the encounter type and relevant clinical documentation.

The coder should focus on information necessary for coding and follow applicable privacy and organizational requirements when handling patient records.

Step 2: Read the Chief Complaint and History

The chief complaint and history can provide important context about why the patient received care.

However, coders must distinguish between symptoms, historical conditions, confirmed diagnoses, and other documented information. The final code selection depends on applicable coding guidelines and the documentation available for the specific encounter.

Step 3: Review the Provider's Assessment

The assessment and documented diagnoses are particularly important during chart review.

Medical coders examine the provider's documentation to identify conditions that are relevant to the encounter and supported for coding.

Coders should never independently diagnose a condition based on symptoms or test results.

Step 4: Review Procedures and Services

Next, coders review documentation describing procedures, examinations, treatments, or other services performed.

This information can help determine appropriate CPT Coding and, where applicable, HCPCS Level II coding.

The coder should compare the documented service with the complete code description and relevant coding instructions.

Step 5: Check Supporting Documentation

Additional sections of a patient chart may provide information that affects code selection.

Depending on the encounter, a coder may review:

• Operative notes
• Diagnostic reports
• Laboratory information
• Imaging reports
• Treatment notes
• Discharge documentation
• Medication information
• Specialist notes

The exact documents reviewed depend on the coding assignment and healthcare setting.

Step 6: Identify the Correct ICD-10-CM Code

For diagnosis coding, the coder generally begins by locating the documented condition in the ICD-10-CM Alphabetic Index and then verifying the selected code in the Tabular List.

The coder checks for:

• Specificity
• Laterality
• Includes notes
• Excludes notes
• Code First instructions
• Use Additional Code instructions
• Required characters

This process helps ensure accurate ICD-10-CM Coding.

Step 7: Verify CPT and HCPCS Codes

For procedures and services, coders review the relevant CPT or HCPCS code descriptions and applicable guidelines.

They should also check whether documentation supports the selected code and whether any applicable modifiers or reporting instructions need to be considered.

Common Chart-Reading Mistakes

Beginners may make mistakes such as:

• Skimming documentation too quickly
• Coding from symptoms without proper support
• Ignoring provider documentation
• Missing laterality
• Choosing unspecified codes unnecessarily
• Ignoring Tabular List instructions
• Assuming information that is not documented
• Selecting codes from memory

Careful and systematic chart review can reduce these errors.
