Irregular menstruation, unspecified

This code represents menstrual cycles that deviate from a regular pattern in terms of frequency, duration, or flow, where the specific type of irregularity (e.g., infrequent, frequent, heavy) has not been documented or definitively diagnosed. It indicates a general disturbance in the menstrual cycle without further specification.

This code is appropriate when documentation indicates "irregular menstruation" without further detail regarding the nature of the irregularity. It can be used when a patient presents with menstrual cycle variations, and the provider has not yet specified whether it involves prolonged intervals, scanty bleeding, shortened intervals, or excessive bleeding.

• Avoid using this code if the documentation specifies the type of irregularity (e.g., oligomenorrhea, polymenorrhea, menorrhagia).
• Review the "Excludes1" notes carefully to ensure this code is not used with more specific codes for irregular menstruation.
• Query the provider for more specific documentation if possible, as a more precise code may be available.
