Chester has an appointment for a check-up on his asthma. He is wheezy and having labored breathing. His established physician performs an expanded problem focused exam and history. No further treatment is recommended. Chester is to return in three months for a checkup on his atopic asthma.

Code it: ICD-9-CM

There is no question here.

To code this scenario using ICD-9-CM, we need to identify the relevant diagnoses and procedure codes. Let's break down the information given:

Diagnoses:
- Asthma (specifically, atopic asthma)

Procedure:
- Expanded problem focused exam and history

1. Asthma - Atopic asthma does not have a specific code in ICD-9-CM. However, we can use the generic code for asthma, which is 493.xx. To be more specific, we can use code 493.90 for unspecified asthma, or if the medical record provides more detail about the specific type of asthma, a more specific code can be assigned.

2. Expanded problem focused exam and history - In ICD-9-CM, the examination codes are grouped under the Evaluation and Management (E/M) codes. Since an expanded problem focused exam and history were performed, we can use an E/M code from the appropriate category. The specific code will depend on the documentation and guidelines used by the healthcare provider. Common E/M codes for office visits include codes from the 992xx series.

To accurately code this scenario, it's recommended to consult the physician's documentation and the official ICD-9-CM coding guidelines to ensure proper coding and billing practices. Additionally, please note that ICD-9-CM has been largely replaced with ICD-10-CM, which is the current coding system used.
