(2022) How To Code Edema ICD 10 – Codes & Guidelines

Edema ICD 10 coding is made easier with our billing guidelines. This article includes all medical codes you will need to report edema and related specific codes, such as pulmonary and periorbital edema.

Read on for a summary of the necessary codes followed by a further description.

What Is Edema? 

Edema (or Oedema) is the abnormal accumulation of fluid in certain tissues within the body.

The definition of edema is observable swelling from fluid accumulation in body tissues. When parts of the body are affected with edema, they are considered edematous. 

The fluid accumulation may be under the skin – usually in dependent areas such as the legs (peripheral edema or ankle edema), or it may accumulate in the lungs (pulmonary edema). 

Symptoms will depend on the cause of the edema.

Symptoms of peripheral edema include swelling of the affected area(s), which causes the surrounding skin to “tighten.”

The swelling from peripheral edema is gravity-dependent (it will increase or decrease with changes in body position).

For example, if a person is lying on their back (supine), swelling will not appear in the legs but in the area around the sacrum.

The skin over the swollen area appears tight and shiny, and often when pressure is applied to the area with a finger, an indentation appears. This is called pitting edema. 

What Is Pulmonary Edema?

In the case of pulmonary edema, there is often no evidence of fluid retention or noticeable swelling on examination of the patient’s extremities.

This is because the fluid is backing up into the lungs. Signs and symptoms of pulmonary edema include:

  • Shortness of breath,
  • Difficulty breathing when lying flat,
  • Waking up breathless,
  • Requiring multiple pillows to raise the head at night for a comfortable sleep.

Causes of edema include:

  • Eating too much salt
  • Sunburn
  • Heart failure
  • Kidney disease
  • Liver problems from cirrhosis
  • Pregnancy
  • Problems with lymph nodes, especially after mastectomy
  • Some medicines
  • Standing or walking a lot when the weather is warm. 

Treatment depends on the condition that causes edema. Generally, the goal of treatment is to reverse the fluid accumulation causing forces;

  • Increase the forces that keep fluid inside the blood vessels.
  • Reduce the forces that cause fluid to leak out of the blood vessels.
  • Identify the cause of the leaking blood vessel walls.

For example, increasing blood protein (albumin) in a malnourished patient can help keep fluids in the bloodstream.

In addition, healing tissues exposed to trauma (for example, inflammation from a bent ankle) helps prevent fluid leakage into blood vessels.

The main goal in the treatment of edema is to remove excess fluid accumulated in the surrounding tissues.

The most common treatment is diuretic. Diuretics make the kidneys excrete excess fluid, which reduces the amount of normal fluid in the body.

However, diuretics should be used caution as dehydration can have serious side effects. In addition, many different diuretics have different mechanisms of action and different strengths.

Edema ICD 10

Edema ICD 10 is coded as R60.

It can be found in chapter XVII of the ICD 10 book, which codes for Symptoms, signs, and abnormal clinical and laboratory findings, not elsewhere classified (R00-R99), under the block R50-R69, which codes for General symptoms and signs, it is found as a broad category R60 which codes for edema not elsewhere classified. 

The subcategories include:

Still, it is classified in chapter X J00-J99 Diseases of the respiratory system under the block J80-J84 Other respiratory diseases principally affect the interstitium and the category J81 Pulmonary edema. 

J81.0 is a billable/specific ICD 10 CM code that can be used to indicate a diagnosis for reimbursement purposes.

The sub-codes include:

J81.0 – Acute pulmonary edema

J81.1 – Chronic pulmonary edema

Lower Extremity Edema ICD 10 

The ICD 10 code for Localized swelling, mass, and a lump in the lower limb is R22.4. 

The sub-codes are:

 R22.4 – Localized swelling, mass, and lump, lower limb.

 R22.40 – Localized swelling, mass, and lump, unspecified lower limb.

 R22.41 – Localized swelling, mass, and lump, right lower limb.

 R22.43 – Localized swelling, mass, and lump, lower limb, bilateral.

Upper limb localized swelling will be coded as: 

R22.3 – Localized swelling, mass, and lump, upper limb.

R22.30 – Localized swelling, mass, and lump, unspecified upper limb.

R22.31 – Localized swelling, mass, and lump, right upper limb.

R22.32 – Localized swelling, mass, and lump, left upper limb.

R22.33 – Localized swelling, mass, and lump, upper limb, bilateral.

However, edematous swelling of the lower limb due to fluid accumulation will be coded as R60.0.

Lower Extremity Edema ICD 10 R22.4.

Peripheral Edema ICD 10

Localized swelling of the limbs will be coded as above. 

While edematous swelling of the limb will be coded as R60.0.

Bilateral Lower Extremity Edema ICD 10

The ICD 10 code for Localized swelling, mass, lump, lower limb, bilateral is R22.43.
