Code also — inherited from J84
Two codes may be needed to describe the condition fully. Whether J84.112 is sequenced first depends on the reason for the encounter.
- , if applicable, associated condition
Code also — inherited from J84.1
Two codes may be needed to describe the condition fully. Whether J84.112 is sequenced first depends on the reason for the encounter.
