![Page 28: HS225 Medical Coding I Unit 9 Seminar Chapters 3 & 4](https://reader036.vdocuments.us/reader036/viewer/2022062315/5697bffb1a28abf838cc0d0d/html5/thumbnails/28.jpg)
Guidelines
Signs and symptoms that are integral to the disease should not be assigned as additional codes.
The etiology and manifestation convention requires two codes to be reported to completely describe a single condition.

Guidelines
Multiple coding for a single condition Use additional code Code first If applicable, code any causal condition
first
Acute (or subacute) and chronic conditions
Combination code versus multiple code

Late Effect
Residual condition that develops after acute phase of illness or injury has ended No time limit on reporting these codes
Combination code assigned For example, painful cicatrix following
severe burn to the elbow or left-sided paralysis due to previous cerebrovascular accident (CVA)
