2025 ICD-10-CM code B94
(Active) Effective Date: N/A Certain infectious and parasitic diseases - Sequelae of other and unspecified infectious and parasitic diseases 1 Feed
This code represents the aftereffects (sequelae) of an infectious or parasitic disease, excluding those specifically classified elsewhere. It includes conditions where the original disease is no longer present.
Medical necessity for services related to sequelae should be supported by documentation that links the current condition to the previous infection and establishes the need for the specific intervention or treatment.
Clinicians should document the original infectious or parasitic disease that caused the sequelae.The specific symptoms, diagnostic findings, and treatment will depend on the nature of the sequelae and the affected organ system.
In simple words: This code signifies the long-term health problems that remain after an infection or parasitic disease has been treated or has gone away on its own. It's used when the original disease is no longer active but has left lasting effects.
This code encompasses the residual effects or aftereffects (sequelae) of infectious and parasitic diseases classified under A00-B89, when the initial disease is no longer present.These sequelae could manifest as various long-term health issues stemming from the original infection. This code should not be used for chronic or current infections, which should be coded to the appropriate active disease code.
Example 1: A patient presents with persistent neurological deficits following recovery from viral encephalitis. The encephalitis is no longer active, and the deficits are considered a sequela. B94.1 (Sequelae of viral encephalitis) would be used., A patient experiences chronic liver dysfunction years after recovering from viral hepatitis. The hepatitis is no longer active. B94.2 (Sequelae of viral hepatitis) is applied., A patient has permanent scarring of the cornea as a result of trachoma. The trachoma infection is resolved. Code B94.0 (Sequelae of trachoma) is assigned.
Documentation should clearly indicate the original infectious or parasitic disease, the current presenting symptoms and signs related to the sequelae, and any diagnostic tests or procedures performed to evaluate the condition.
** It is crucial to distinguish between chronic, active infections and sequelae. This code should only be used when the original infection is no longer present, and the patient is experiencing residual effects or aftereffects. For chronic or current infections, code the active infectious disease.
