Edema ICD-10-CM Codes

What are Edema ICD-10-CM Codes?

There are three primary Edema ICD-10-CM codes commonly used for accurate coding and billing purposes:

• R60.9 – Edema, unspecified: This ICD-10 code is used when a patient is diagnosed with edema, but the specific type (such as localized edema or generalized edema) is unknown or not documented. It’s commonly linked to fluid retention without clear specification and may relate to several underlying conditions such as heart failure, infection, or venous insufficiency.
• R60.0 – Localized edema: This code applies when swelling occurs in a defined or specific area such as the ankles, legs, or face. Localized fluid accumulation can result from trauma, varicose veins, birth injury, inflammation, or infection. Documenting the affected area and the underlying cause for correct coding is especially important.
• R60.1 – Generalized edema: This refers to swelling involving the entire body or widespread regions, often due to systemic diseases such as kidney failure, liver disease, or gestational edema during pregnancy. It signifies fluid accumulation affecting multiple tissues.

These ICD-10-CM codes are valid and billable but should not be used as principal diagnoses. Clinicians must identify and report the underlying cause—be it congestive heart failure, nephrotic syndrome, or another abnormal clinical condition—as the primary diagnosis. The edema code may be an additional diagnosis to reflect signs and symptoms.

Which Edema ICD-10-CM Codes are billable?

All ICD-10-CM codes are valid and billable, but should not be used as principal diagnoses. Clinicians must identify and report the underlying cause—be it congestive heart failure, nephrotic syndrome, or another abnormal clinical condition—as the primary diagnosis. The edema code may be an additional diagnosis to reflect signs and symptoms.

Clinical information

Edema is swelling caused by excess fluid trapped in the body’s tissues. It can appear in nearly any body part but is most commonly seen in the lower extremities—especially the legs, ankles, and feet. The fluid retention may occur gradually or suddenly, depending on the cause.

There are two broad classifications:

• Localized edema: Limited to a specific area, such as peripheral edema in the limbs, cerebral edema in the brain, or larynx and pharynx swelling, which can become life-threatening.
• Generalized edema: Involves widespread fluid accumulation, often due to systemic diseases.

Patients with edema often present with the following symptoms and clinical signs:

• Visible swelling or enlargement of an area due to fluid buildup
• Shiny or stretched skin over the affected area
• Tightness, pain, or discomfort, particularly with movement
• In severe cases, mobility issues or difficulty breathing (especially with pulmonary or cerebral edema)

To ensure accurate coding and avoid claim denials, providers must clearly document:

• Whether the edema is localized or generalized
• The underlying condition (e.g., heart failure, infection, venous insufficiency)
• Any associated laboratory findings, diagnostic imaging, or physical exam results
• Affected body regions (e.g., lower extremities, entire body, larynx, pharynx)
• Relevant symptoms like discomfort, restricted range of motion, or skin changes

Synonyms include

• Acute edema

• Exudative edema
• Firm nonpitting edema
• Firm pitting edema
• Generalized edema
• Idiopathic edema
• Infectious edema
• Localized edema
• Non-pitting edema
• Periodic edema
• Peripheral edema
• Pitting edema
