Range Overview
The ICD-10 category B90-B94 represents codes for sequelae of infectious and parasitic diseases. Sequelae are conditions that occur as a direct result of a previous disease or injury. This category includes codes for late effects of diseases such as tuberculosis, poliomyelitis, and other infectious and parasitic diseases. The codes are used to document the long-term effects of these diseases, even after the acute phase has resolved.
Key Usage Points:
- •These codes are used when a patient has a current condition that is a direct result of an infectious or parasitic disease.
- •The codes should be used in conjunction with the code for the current condition.
- •The codes in this category are not used for the initial infection or disease.
- •The codes should be used regardless of the time elapsed since the initial infection or disease.
- •The codes can be used for patients of all ages.
Coding Guidelines
When to Use:
- ✓When a patient presents with a condition that is a direct result of a past infectious or parasitic disease.
- ✓When the initial infectious or parasitic disease has resolved, but the patient is still dealing with the effects.
- ✓When the patient's current condition can be directly linked to a past infectious or parasitic disease.
- ✓When the patient has a history of an infectious or parasitic disease and is experiencing related complications.
When NOT to Use:
- ✗When the patient is currently experiencing the initial infectious or parasitic disease.
- ✗When the patient's current condition cannot be directly linked to a past infectious or parasitic disease.
- ✗When the patient has no history of an infectious or parasitic disease.
- ✗When the patient's current condition is not a known or common sequelae of an infectious or parasitic disease.
Code Exclusions
Always verify the patient's medical history and current condition before assigning a B90-B94 code.
Documentation Requirements
Documentation for B90-B94 codes should clearly link the patient's current condition to a past infectious or parasitic disease. The documentation should include the patient's medical history, current symptoms, and any relevant diagnostic tests or procedures.
Clinical Information:
- •Patient's medical history
- •Current symptoms and conditions
- •Link between current condition and past disease
- •Diagnostic tests and procedures
- •Treatment plan
Supporting Evidence:
- •Medical records
- •Lab results
- •Imaging studies
- •Physician's notes
Good Documentation Example:
Patient presents with post-polio syndrome. Patient has a history of poliomyelitis at age 6. Symptoms include muscle weakness and fatigue.
Poor Documentation Example:
Patient presents with muscle weakness and fatigue.
Common Documentation Errors:
- ⚠Not linking the current condition to a past disease
- ⚠Not documenting the patient's medical history
- ⚠Not including relevant diagnostic tests or procedures
Range Statistics
Coding Complexity
The complexity of B90-B94 codes is medium due to the need to understand the patient's medical history and the link between the current condition and the past disease. It also requires identifying the correct codes for both the current condition and the past disease.
Key Factors:
- ▸Determining the link between the current condition and the past disease
- ▸Understanding the patient's medical history
- ▸Identifying the correct code for the current condition
- ▸Identifying the correct code for the past disease
Specialty Focus
B90-B94 codes are commonly used in infectious disease, pulmonology, and neurology specialties. They are used to document the long-term effects of diseases such as tuberculosis, poliomyelitis, and other infectious and parasitic diseases.
Primary Specialties:
Clinical Scenarios:
- • A patient with a history of tuberculosis presents with chronic respiratory symptoms.
- • A patient presents with post-polio syndrome.
- • A patient with a history of a parasitic disease presents with chronic gastrointestinal symptoms.
- • A patient presents with neurological symptoms linked to a past infectious disease.

Frequently Asked Questions
Can a B90-B94 code be used for a patient with a current infectious or parasitic disease?
No, B90-B94 codes are used for the sequelae, or late effects, of infectious and parasitic diseases. They should not be used for the initial infection or disease.
