What A08 covers · when clinicians use it
ICD-10 code A08 identifies Viral and other specified intestinal infections in the U.S. ICD-10-CM clinical and billing record set. It sits within the Certain Infectious and Parasitic Diseases chapter (A00–B99), the section that groups related diagnoses so providers, payers, and public-health agencies report them consistently. Clinicians and medical coders apply A08 when an encounter's findings match the Viral and other specified intestinal infections description, attaching it to the patient record so downstream insurance claims, payer audits, quality reporting, and epidemiological surveillance all reference the same standardized diagnosis. The ICD-10-CM is maintained by the Centers for Medicare & Medicaid Services and the CDC's National Center for Health Statistics, with an updated official code set released each U.S. fiscal year — always verify A08 against the current CMS/CDC release and your payer's documentation guidance before final use. This page summarizes documentation context for A08 and is a coding reference, not clinical, diagnostic, or billing advice.
A08 represents Viral and other specified intestinal infections, a condition that requires accurate identification in clinical records for proper treatment and public health reporting. This ICD10 code ensures standardization in documenting patient diagnoses across healthcare systems. Its use helps physicians, coders, and billing teams communicate effectively and enables data analysis for trends, outbreaks, and treatment outcomes. Knowing what this ICD10 code means is crucial for medical professionals handling patient records and claims.
Symptoms
- Watery diarrhea – Frequent, loose, or watery stools
- Abdominal cramps – Sharp or dull pain in the stomach area
- Fever – Elevated body temperature, often with chills
- Nausea – Urge to vomit with or without actual vomiting
- Vomiting – Expulsion of stomach contents through the mouth
- Dehydration – Dry mouth, low urine output, dizziness
- Fatigue – Unusual tiredness and weakness
Diagnosis
Diagnosis of Viral and other specified intestinal infections typically involves a thorough clinical history and physical examination, focusing on gastrointestinal symptoms. Laboratory tests such as stool cultures, antigen detection, or PCR may be used to confirm the causative organism. In some cases, blood tests are conducted to assess electrolyte balance, signs of infection, or dehydration. Imaging is not usually required unless complications are suspected. Early diagnosis is essential for effective treatment and to prevent complications or transmission.
ICD10 Code Usage
ICD10 code A08 is used in electronic health records (EHRs), billing systems, and clinical documentation. Medical coders assign this code to patient records to standardize reporting across healthcare providers. It enables accurate billing for insurance claims, supports epidemiological tracking, and contributes to healthcare analytics. Healthcare organizations also use ICD10 codes for quality reporting, audits, and public health initiatives, making consistent use essential.
