Excessive, frequent and irregular menstruation (N92)
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.

Instructional Notations
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Menorrhagia
Excessive uterine bleeding during MENSTRUATION.
Menstruation
The periodic shedding of the ENDOMETRIUM and associated menstrual bleeding in the MENSTRUAL CYCLE of humans and primates. Menstruation is due to the decline in circulating PROGESTERONE, and occurs at the late LUTEAL PHASE when LUTEOLYSIS of the CORPUS LUTEUM takes place.
