ICD-10 Code O98.5: Other viral diseases complicating pregnancy, childbirth and the puerperium
Reviewed by HealthAssure Clinical TeamUpdated 26 May 2026
What is this code?
ICD-10 entries help standardize how diagnoses are organized for coding, reporting, analytics, and documentation. This code sits within the broader ICD-10 area for Pregnancy, childbirth and the puerperium (O00-O9A).
đź“‹Clinical overview
This ICD-10 overview page groups maternal other-viral-disease complication codes under a broad all-timing parent code. The most accurate billable code usually depends on maternal timing and whether the underlying viral illness is named more specifically.
When is it used?
- May be used when a clinician documents other viral diseases complicating pregnancy, childbirth and the puerperium in a patient's medical record.
- May appear in hospital records, claims, referrals, and clinical documentation.
- This code may act more like a grouping or parent code, so a more specific child code may be used in final documentation when available.
What it does not mean
- A code alone does not explain severity, treatment plan, or outcome.
- A medical code should not be treated as a substitute for a doctor's diagnosis or advice.
- This entry may represent a broader category rather than the most specific billable code.
đź©şClinical context
When commonly used
- Parent-code browsing, coding review, and clinical-reference workflows where the goal is to understand the broader maternal-other-viral-disease complication family before selecting a timing-specific child code.
- Documentation review where a maternal viral illness is clearly linked to obstetric care, but the user is navigating the all-timing umbrella page rather than a pregnancy, childbirth, or puerperium child page.
Common workup
- Related procedures or service context already linked on this page include Obstetric ultrasound, Fetal nonstress testing.
Common management context
- Overview-level review often includes maternal symptom context, treatment planning, obstetric monitoring, and coordination of pregnancy or postpartum follow-up.
- The final billable code usually becomes more specific when the chart identifies maternal timing and the exact viral illness elsewhere in the record.
- Specialist context already linked on this page includes Obstetrician, Gynecologist, Infectious Disease Specialist.
🔍Key distinctions
Important notes
- This parent page is an umbrella overview for maternal other-viral-disease complication codes rather than the most specific billable child code.
- Maternal timing and the named viral illness are the main specificity drivers across this family.
- This overview page groups maternal other-viral-disease complication codes across pregnancy, childbirth, and the puerperium, so the final billable code usually depends on maternal timing and whether the underlying viral illness is named more specifically.
Important exclusions
- human immunodeficiency virus [HIV] disease complicating pregnancy, childbirth and the puerperium (O98.7-)
