Code Description

ICD-10 R68.12 is a billable code used to indicate a diagnosis of fussy infant (baby).

Key Diagnostic Point:

R68.12 refers to a clinical presentation characterized by excessive fussiness or irritability in infants, which is often a common concern among parents and caregivers. This symptom can manifest as persistent crying, difficulty in soothing, and general restlessness, leading to distress for both the infant and the family. The causes of fussiness in infants can be multifactorial, including hunger, discomfort, fatigue, or underlying medical conditions such as gastroesophageal reflux disease (GERD), colic, or infections. It is essential for healthcare providers to conduct a thorough assessment to rule out any serious underlying issues. The diagnostic approach typically involves a detailed history and physical examination, focusing on feeding patterns, sleep habits, and any associated symptoms. Laboratory tests may be warranted if there are signs of infection or metabolic disorders. Accurate coding of R68.12 requires careful documentation of the infant's symptoms, duration, and any interventions attempted to alleviate the fussiness.
