These guidelines can aid your sequela character selection. PM practices see their share of patients who experience a reemergence of signs or symptoms from a prior injury after the initial injury subsides. When a patient experiences these symptoms, the manifestations are known as sequela effects. You'll have several diagnostic considerations to take into account for correct sequela coding; also, you won't get far without an understanding of the rules ICD-10 implemented in coding for such sequela effects. Help's here: Turn to this rundown of examples and expert advice, and seek success for every sequela coding scenario. Know Sequela Definition The ICD-10-CM guidelines define a sequela effect as the following: Example: A patient experiences headaches in the days and weeks while recovering from a facial trauma; you would not consider these symptoms to be sequela effects. However, if the patient experiences symptoms in the months and years since she has fully recovered from the initial traumatic incident or operation, you may consider these symptoms to be sequela effects. With these examples in mind, sequela coding can be understandably difficult do to the subjective nature of the manifestations. Follow the Guidelines on Sequela Coding As you will see in the ICD-10 guidelines, the information on sequela coding isn't necessarily localized to one particular section. With this in mind, it's important that coders know how to maneuver through the guidelines to identify all the vital elements within their search criteria. The first point of reference comes with identifying the number and order of codes assigned. ICD-10-CM guidelines state: ICD-10-CM uses the example of scar formation following a burn to illustrate the point of using two separate ICD-10-CM codes: However, before you go searching for two separate codes, consider these supplementary guidelines: There's a few points to unpack, here. First, you won't necessarily come across many, if any, examples of a sequela followed by a manifestation code note in the ICD-10-CM tabular. On the other hand, you may come across examples in which a sequela code has been expanded to include manifestations.
