W35.XXXS is a sequela code, includes a 7th character and should be used for complications that arise as a direct result of a condition like explosion and rupture of boiler. According to ICD-10-CM Guidelines a "sequela" code should be used for chronic or residual conditions that are complications of an initial acute disease, illness or injury. The most common sequela is pain. Usually, two diagnosis codes are needed when reporting sequela. The first code describes the nature of the sequela while the second code describes the sequela or late effect.
