  • Pregnancy, childbirth and the puerperium
    (O00-O9A)
    • Maternal care related to the fetus and amniotic cavity and possible delivery problems
      (O30-O48)
      • Other disorders of amniotic fluid and membranes
        (O41)

O41 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of other disorders of amniotic fluid and membranes. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Type 1 Excludes

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.
  • encounter for suspected maternal and fetal conditions ruled out Z03.7

7th Character Note

7th Character Note
Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
  • One of the following 7th characters is to be assigned to each code under category O41. 7th character 0 is for single gestations and multiple gestations where the fetus is unspecified. 7th characters 1 through 9 are for cases of multiple gestations to identify the fetus for which the code applies. The appropriate code from category O30

7th Character

7th Character
Indicates that a seventh character is to be assigned to codes in a subcategory.
  • 0 - not applicable or unspecified
  • 1 - fetus 1
  • 2 - fetus 2
  • 3 - fetus 3
  • 4 - fetus 4
  • 5 - fetus 5
  • 9 - other fetus
