Acute Versus Chronic Conditions Coding Guide

When coding medical conditions, it’s important to understand the difference between acute and chronic conditions. Acute conditions are those that develop suddenly and often have a short duration, while chronic conditions are long-term conditions that persist over time.

Here are some general coding guidelines for acute and chronic conditions:

Acute Conditions:

• Assign codes for acute conditions when the condition is actively being treated, such as during a hospital admission or an outpatient visit.
• Assign codes for any ongoing symptoms related to the acute condition, even if the condition has resolved.
• Use codes that identify the underlying cause of the acute condition, such as a viral infection or injury.
• If the acute condition is a complication of a chronic condition, sequence the code for the acute condition first, followed by the code for the chronic condition.

Chronic Conditions:

• Assign codes for chronic conditions that are being actively treated or monitored, such as during an outpatient visit or follow-up appointment.
• Use codes that identify the specific chronic condition, such as diabetes or hypertension.
• Assign additional codes for any manifestations or complications of the chronic condition, such as diabetic neuropathy or hypertensive heart disease.
• Sequence the codes based on the reason for the encounter. If the visit is primarily for treatment of the chronic condition, sequence the code for the chronic condition first, followed by any codes for complications or manifestations.

It’s important to note that these are general guidelines, and there may be exceptions depending on the specific circumstances of each case. Additionally, accurate coding requires a thorough understanding of the medical terminology and the coding guidelines established by the relevant coding systems, such as ICD-10-CM.
