About the N92 Code Range
ICD-10 code section N92 is used to classify various types of excessive, frequent, and irregular menstruation. It includes codes for conditions ranging from heavy or frequent periods with a regular cycle to irregular bleeding patterns and menstrual irregularities at different life stages such as puberty and premenopause.
The codes cover a wide range of menstrual disorders. For example, N92.0 identifies excessive and frequent menstruation with a regular cycle, commonly referred to as menorrhagia or polymenorrhea. N92.1 is used when menstruation is both excessive and frequent but with an irregular cycle, including terms like mid-cycle bleeding and menometrorrhagia. N92.2 specifies excessive menstrual bleeding during puberty (pubertal menorrhagia), while N92.4 refers to heavy bleeding in the premenopausal period. Other codes such as N92.3 denote ovulation bleeding, and N92.5 capture other specified irregular menstruation patterns like prolonged or postponed periods. The unspecified code N92.6 addresses irregular menstruation when the exact pattern is not identified. This detailed classification helps healthcare providers and coders accurately document and address specific menstrual disorders using the correct ICD-10 codes.
