Modifier -62 is used when two surgeons of different specialties each perform distinct portions of a procedure requiring unique skills.

Question 2

In ICD-10-CM, what does a code listed as the 'default code' in the Alphabetic Index represent?

The most common or unspecified condition when no further detail is provided

Answer

The default code is the most frequently associated code for a condition when the record lacks sufficient detail to assign a more specific code.

Question 3

When a patient has both a related complication and the underlying condition, how should they generally be coded?

Accepted Answer

Code both, with sequencing based on reason for the encounter

Report it only with its designated primary procedure code

Add-on codes are always reported with their primary procedure code and are exempt from the multiple procedure modifier -51.
