Study Notes

Certain Infectious and Parasitic Diseases (Codes A00-B99)

Chapter 1 covers infectious and parasitic diseases, requiring careful coding practices.
Coding may involve multiple codes: one for the organism, one for the condition, a combination code, or a single code.

Coding for Specific Diagnoses

For AIDS patients with meningitis caused by histoplasmosis, use codes B20 (HIV disease), B39.9 (unspecified histoplasmosis), and G02 (meningitis).
Always consult the ICD-10-CM Alphabetic Index and follow notes and directives in the Tabular List for accurate coding.

Coding and Sequencing Practices

In inpatient settings, HIV must be confirmed for coding; other conditions marked as probable or suspected are coded as existing.
When admitting a patient for an HIV-related condition, code B20 should be sequenced first, followed by additional HIV-related conditions.

Opportunistic Infections

Common HIV-related conditions include Kaposi's sarcoma, lymphoma, PCP, cryptococcal meningitis, and cytomegaloviral disease.
A complete list of opportunistic infections defining AIDS can be found on the CDC's website.

Asymptomatic HIV

Use code Z21 for asymptomatic HIV infection status when a patient is HIV positive but lacks documented symptoms.
R75 indicates inconclusive laboratory evidence of HIV with no definitive diagnosis.

During pregnancy, use codes from O98.7- for HIV complicating pregnancy and Z21 if the patient is asymptomatic.
When treating an HIV-related illness in pregnant women, sequence properly with O98.7 first, followed by B20 and relevant codes.

HIV Testing and Counseling

Use code Z11.4 for encounters that focus on HIV screening.
If there are signs or symptoms related to HIV, code the signs/symptoms or the confirmed diagnosis instead of just positive test results.

Documenting Complications and Secondary Conditions

For a symptomatic HIV patient presenting with unrelated conditions, such as an ankle sprain, the injury should be coded first, followed by B20.
Code B20 must be reported alongside any HIV-related conditions during visits for unrelated issues.

Additional Coding Examples

Toxic shock syndrome due to Staphylococcus aureus requires codes A48.3 for the syndrome and B95.61 for the causative organism.
For pneumonia resistant to penicillin, use code J18.9 for unspecified pneumonia and Z16.11 for resistance to penicillin.

Severe Sepsis Coding

R65.2 for severe sepsis should only be used when severe sepsis with acute organ dysfunction is documented.
Severe sepsis requires two codes: one for the systemic infection (e.g., A41.9) and one from R65.2, along with additional codes for each identified organ dysfunction.

Clinical Example of Sepsis

For a patient with sepsis, acute kidney failure, and bladder cancer, the proper coding sequence depends on the documented cause of the acute kidney failure, potentially including A41.9, R65.20, N17.9, and C67.9 in the sequence based on clinical findings.
