Code Classification

  • Pregnancy, childbirth and the puerperium
    (O00-O9A)

      • Maternal care for abnormality of pelvic organs

O34.40 is a billable diagnosis code used to specify a medical diagnosis of maternal care for other abnormalities of cervix, unspecified trimester. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

The code O34.40 is applicable to female patients aged 12 through 55 years inclusive. It is clinically and virtually impossible to use this code on a non-female patient outside the stated age range.

Unspecified diagnosis codes like O34.40 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

The maternity code edits apply to patients age ange is 9–64 years inclusive (e.g., diabetes in pregnancy, antepartum pulmonary complication).
  • Diagnoses for females only - The Medicare Code Editor detects inconsistencies between a patient’s sex and any diagnosis on the patient’s record, these edits apply to FEMALES only .

  • ICD-9-CM Code: 654.60 - Abn cervix NEC preg-unsp
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education


Cervix Disorders

The cervix is the lower part of the uterus, the place where a baby grows during pregnancy. The cervix has a small opening that expands during childbirth. It also allows menstrual blood to leave a woman's body.

Your health care provider may perform a Pap test during your health checkup to look for changes to the cells of the cervix, including cervical cancer. Other problems with the cervix include:

  • Cervicitis - inflammation of the cervix. This is usually from an infection.
  • Cervical incompetence - This can happen during pregnancy. The opening of the cervix widens long before the baby is due.
  • Cervical polyps and cysts - abnormal growths on the cervix

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
