Summary
No coding relationship between these codes was found in the tabular notes or in MedCoder’s derived relationships.
- What is different?
The conditions named and chapter.K56.5 is “Intestinal adhesions [bands] with obstruction (postinfection)”; P76 is “Other intestinal obstruction of newborn”. K56.5 sits in K00-K95 — Diseases of the Digestive System (K00-K95); P76 in P00-P96 — Certain Conditions Originating in the Perinatal Period (P00-P96).
Registry fact
- Is one a parent or header code?
Both are headers.Both are non-billable headers, and neither contains the other.
Registry fact
Nothing found in 5 other checks; 1 check does not apply
- Can these codes be reported together?
No instruction prevents it.No note in either entry names the other, and no derived relationship links them. Each may be reported when its own documentation requirements are met.
Registry fact
- Is there an Excludes1 relationship?
None.Neither entry carries an Excludes1 note that names the other code. K56.5 carries 7 Excludes1 notes covering other codes; the side-by-side table quotes them.
Official rule
- Is there an Excludes2 relationship?
None.Neither entry carries an Excludes2 note that names the other code. K56.5 carries 1 Excludes2 note covering other codes; the side-by-side table quotes them.
Official rule
- Is one more specific?
Not comparable.The codes sit in different categories; specificity is only comparable within one category.
- 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.
No Excludes1/Excludes2 relationship exists between these codes in the official tabular list. Each may be reported when its own documentation requirements are met.
Side by side
Similar descriptions do not make codes interchangeable. The documentation and the official instructions decide which code applies.

K56 Paralytic ileus and intestinal obstruction without hernia
Is itself a category
K00-K95 — Diseases of the Digestive System (K00-K95)
P00-P96 — Certain Conditions Originating in the Perinatal Period (P00-P96)
- Abdominal hernia due to adhesions with obstruction
- Peritoneal adhesions [bands] with intestinal obstruction (postinfection)
None at this code
No Code first, Use additional code, Code also and 7th character note at either code.
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. In a row that differs, each code’s own notes are listed under it, and the notes every code shares are listed once beneath them.
