ICD-10 Code O99.6: Diseases of the digestive system 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 digestive-system complication codes under a broad parent code. The most accurate billable code usually depends on whether the record specifies pregnancy versus childbirth versus puerperium timing and whether the underlying gastrointestinal or hepatobiliary diagnosis is named more specifically.
When is it used?
- May be used when a clinician documents diseases of the digestive system 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 digestive complication family before selecting a timing-specific child code.
- Documentation review where the chart clearly links digestive disease to obstetric care, but the user is navigating the broad umbrella page rather than a more specific 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 symptom review, nutrition or hydration assessment context, medication review, obstetric monitoring, and coordination with gastroenterology or maternal-fetal medicine.
- The final billable code usually becomes more specific when the chart identifies maternal timing and the underlying gastrointestinal or hepatobiliary diagnosis elsewhere in the record.
- Specialist context already linked on this page includes Obstetrician, Gynecologist, Gastroenterologist.
🔍Key distinctions
Important notes
- This parent page is an umbrella overview for multiple maternal digestive-system complication codes rather than the most specific billable child code.
- Maternal timing and the underlying digestive diagnosis are the key distinctions across this family.
- This overview page groups maternal digestive-system-disease codes across pregnancy, childbirth, and the puerperium, so the final billable code usually depends on maternal timing and whether the chart identifies a more specific gastrointestinal or hepatobiliary condition.
Important exclusions
- hemorrhoids in pregnancy (O22.4-)
- liver and biliary tract disorders in pregnancy, childbirth and the puerperium (O26.6-)
