O64.0XX1 vs O64.0XX2
O64.0XX1 (Obstructed labor due to incomplete rotation of fetal head, fetus 1) compared with O64.0XX2 (Obstructed labor due to incomplete rotation of fetal head, fetus 2), from the official CMS tabular data.
Summary
No tabular note links these codes. Both belong to category O64, and nothing in the tabular list prevents reporting each when it is documented.
Registry fact- What is different?
Title wording.The titles differ in one word, “1” (O64.0XX1) versus “2” (O64.0XX2): O64.0XX1 is “Obstructed labor due to incomplete rotation of fetal head, fetus 1”; O64.0XX2 is “Obstructed labor due to incomplete rotation of fetal head, fetus 2”.
Registry fact
- Can these codes be reported together?
No instruction prevents it.No note in either entry names the other. Both belong to category O64; each may be reported when its own documentation is present.
Registry fact
- Is there an Excludes1 relationship?
None.Neither entry carries an Excludes1 note that names the other code.
Official rule
- Is there an Excludes2 relationship?
None.Neither entry carries an Excludes2 note that names the other code.
Official rule
- Is one more specific?
No.Neither is a subdivision of the other, and neither title is the unspecified form; they describe different conditions within category O64.
Registry fact
- Is one a parent or header code?
No.Both are billable codes, and neither contains the other.
Registry fact
- Are there sequencing instructions?
None.Neither entry carries a Code First or Use Additional Code note that names the other.
Official rule
- Are there other coding relationships?
None found.No laterality, encounter-phase, Table of Neoplasms, Table of Drugs and Chemicals, or history-versus-active-disease relationship links these codes.
MedCoder-derived
Official rule: a tabular instructional note or a section of the ICD-10-CM Official Guidelines, quoted as published. Registry fact: the codes’ own published attributes (titles, billable status, position in the hierarchy, code set). MedCoder-derived: a reading MedCoder computes from those facts; it is not itself a rule. How to read the labels
Can these codes be reported together?
Yes, when each is documented. O64.0XX1 and O64.0XX2 both belong to category O64.
No Excludes1/Excludes2 relationship exists between these codes in the official tabular list. The code titles state what each one covers, and the documentation decides which applies.

| 7th character | One of the following 7th characters is to be assigned to each code under category O64. 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, Multiple gestation, must also be assigned when assigning a code from category O64 that has a 7th character of 1 through 9. | One of the following 7th characters is to be assigned to each code under category O64. 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.

Notes are the code’s own tabular entry, quoted as published. A note that names the other code is the one the verdict above rests on.
