What does 'sequelae or late effect' require in coding?

'Sequelae or late effect' coding in ICD-10-CM requires two separate codes to accurately convey the complete clinical picture. This is because when coding for sequelae, one code is needed for the original condition that caused the sequela, and another code is required to specify the late effect or the residual condition itself.

For instance, if a patient has a condition like a stroke that results in paralysis, the coder would use one code for the stroke (the original condition) and a second code for the paralysis (the sequela). This coding practice allows for a thorough and precise understanding of the patient's medical history and ensures that healthcare providers and insurers have clear information regarding the patient's ongoing challenges stemming from previous injuries or illnesses. Properly following this coding guideline supports effective communication in the healthcare setting, optimizes patient care, and assists in appropriate reimbursement processes.
