ICD-9-CM 486

CMS Source: final ICD-9-CM release (version date October 1, 2014). Retired from U.S. claims after September 30, 2015.

486 is a legacy ICD-9-CM diagnosis code for pneumonia, organism unspecified. It was valid on U.S. claims through September 30, 2015 and cannot be reported for services on or after October 1, 2015, when ICD-10-CM replaced the ICD-9 code set. Under the CMS General Equivalence Mappings, its ICD-10-CM replacement is J18.9 (Pneumonia, unspecified organism), flagged as an approximate match.

Information for Patients

Pneumonia

Pneumonia is an infection in one or both of the lungs. It causes the air sacs of the lungs to fill up with fluid or pus. It can range from mild to severe, depending on the type of germ causing the infection, your age, and your overall health.

Questions About 486

Is 486 (pneumonia, organism unspecified) still a valid code?

No. This code belonged to ICD-9-CM, which the United States retired after September 30, 2015. Claims with dates of service on or after October 1, 2015 must use ICD-10-CM codes, such as its replacement J18.9.

What is the ICD-10 replacement for 486?

The General Equivalence Mappings crosswalk this code to ICD-10-CM J18.9 (Pneumonia, unspecified organism). The match is flagged as approximate, so confirm it against the clinical documentation before use.

What did 486 mean?

In the final ICD-9-CM release, this code described pneumonia, organism unspecified. It sat in block 486 Pneumonia, organism unspecified under Diseases of the respiratory system (460–519).
