Excessive crying of infant (baby)

This code signifies persistent, inconsolable crying in an infant, typically under 12 months of age, that is not attributable to an obvious medical cause or hunger. It often describes what is commonly referred to as colic or fussiness in babies.

Apply this code when documentation specifies an infant experiencing prolonged, unexplained crying episodes. This diagnosis is appropriate when other potential causes for crying (e.g., hunger, discomfort, illness) have been ruled out or are not the primary focus of the encounter.

• Ensure the patient's age is clearly documented as an infant to differentiate from crying in older individuals.
• Do not code this with R45.83, as that code is for excessive crying in children, adolescents, or adults.
• Consider co-reporting with codes for associated symptoms or underlying conditions if identified, such as feeding difficulties (e.g., R63.3) or gastroesophageal reflux (e.g., K21.9).
