ICD-10-CM Code J91.8
Pleural effusion in other conditions classified elsewhere

Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
Manifestation Code
Certain ICD-10-CM codes identify an underlying condition known as an etiology code. Conditions that arise as a result of an underlying condition (etiology), are referred to as Manifestations. In ICD-10-CM, etiology codes must be coded first, followed by the manifestation codes. When a condition requires etiology and manifestation codes, there is a "use additional code" note following the etiology code and a "code first" note following the manifestation code.

J91.8 is a billable ICD code used to specify a diagnosis of pleural effusion in other conditions classified elsewhere. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code J91 is used to code Chylothorax

A chylothorax (or chyle leak) is a type of pleural effusion. It results from lymph formed in the digestive system called chyle accumulating in the pleural cavity due to either disruption or obstruction of the thoracic duct.

Coding Advice SNOMET-CT

  • Consider additional code to identify specific condition or disease
  • This is a manifestation code for use in a secondary position


Unspecified pleural effusion (approximate match)

This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code J91.8 and a single ICD9 code, 511.9 is an approximate match for comparison and conversion purposes.
