Use your code books and write your reasoning before opening the walkthrough. This exercise contains no real patient information.

Visit context

Fictional patient Mara Ellis, age 58, returns to the same family physician who treated her four months ago. This is one scheduled office encounter for management of essential hypertension, the main reason for the visit. She also asks the physician to review her established type 2 diabetes treatment. There is no preventive examination, Medicare wellness visit or separate procedure today.

History and examination

The patient brings her home blood-pressure record. She reports taking amlodipine as prescribed, without new dizziness, chest pain or shortness of breath. Blood pressure is 128/76 and the physician documents a stable cardiopulmonary examination. She continues metformin for type 2 diabetes. The physician records no hypoglycemic episodes and explicitly documents diabetes without complications, not in remission. No kidney disease, heart failure or tobacco exposure is documented. A family member’s diabetes appears only in the family history.

Assessment and management

The signed assessment states: essential hypertension, stable on current treatment; type 2 diabetes mellitus without complications, stable on current oral therapy. The physician evaluates adherence and response for both conditions, decides to continue each prescription and renews them. The physician discusses home monitoring and follow-up. The metformin is ongoing long-term treatment, not a temporary inpatient medication. There is no insulin or injectable non-insulin diabetes drug use.

Work and timing

The physician documents 25 minutes of personal qualifying work on this service date, including record review, the visit, counseling and completion of the note. Staff rooming time is excluded. No separately reported service is included in the total. The exercise asks you to compare the licensed time and medical-decision-making routes, then report one supported office E/M service. It does not ask for two visit charges because two selection methods are available.

Coding desk

Abstract the reason chiefly responsible for the encounter, the second condition actually managed and the required oral-diabetes-medication status. Verify the exact ICD-10-CM entries. Use the current licensed E/M instructions to select one supported level and record which method supports it. Any other medication-status entry you propose needs its own relevance and Tabular review; do not replace the required diabetes medication-status code with a generic status entry.

Your coding worksheet

  1. Identify the reason for this encounter and the supported diagnoses.
  2. List the services actually completed and the applicable code sets.
  3. Use your books to select final codes, units and any supported modifiers.
  4. Sequence the diagnoses and explain the relevant instruction.
  5. Review included work and any separate coverage question. Explain why the strongest alternative does not fit.

In your notebook, record the supported facts, your index route, the instructions you checked, and any missing detail that limits your answer.

Write your answer

Use only this fictional record. Your entries stay on this page and disappear when you leave or reload. Do not enter real patient information.

Compare with the worked explanation
  1. The visit is for active disease management, not screening or a wellness benefit. The same physician provided care four months earlier, so review the established-patient office pathway.
  2. Essential hypertension is the stated main reason: verify I10. The separately managed diabetes without complications supports E11.9; the chart explicitly excludes remission and does not document a complication.
  3. E11 carries an additional-code instruction for the means of control. Ongoing metformin supports Z79.84. Z79.4 and Z79.85 do not match this medication record. Do not infer the patient has a condition solely from family history.
  4. Use I10 first for the reason chiefly responsible for this visit, then E11.9 with the applicable medication-status reporting. Do not rank diagnoses by perceived severity or alphabet.
  5. Use the licensed book to compare the complete MDM facts with the 25-minute time route. Choose one supported E/M entry; the two methods do not create two services. The worksheet is not complete until you record the exact entry and supporting method in your own book notes.
  6. No procedure or separate wellness service is documented, so the record supplies no reason to invent a separate-procedure modifier or wellness claim. Coverage remains a separate payer review; correct code selection alone does not promise payment.
