About the B91 Code Range

ICD-10 code B91 is used to identify the long-term effects or sequelae that follow an initial poliomyelitis infection. This code specifically captures the late complications that can develop well after the acute phase of poliomyelitis has resolved.

Sequelae of poliomyelitis refers to a variety of chronic conditions that may arise, including muscle weakness known as paresis, and bone or joint problems such as osteopathy affecting the feet or ankles on one or both sides. The code B91 also covers neurological complications like neurogenic urinary bladder caused by nerve damage from the original infection. Synonyms such as late effects of poliomyelitis highlight that these issues occur as persistent consequences rather than during the active illness. For medical coders and healthcare professionals, using ICD-10 code B91 ensures accurate documentation of these specific long-term effects, which helps guide ongoing patient management and treatment. This makes it an essential code for identifying late-stage poliomyelitis conditions in clinical and billing contexts.
