Which MS-DRGs does F72 group to?
F72 sits in MDC 19 and helps define the logic of 1 MS-DRG (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 884Organic Disturbances and Intellectual Disabilitymedical
As a secondary diagnosis, F72 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
How is F72 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to F72. They show the wording a clinician may have documented, which often differs from the Tabular description.
- I.Q. › 20-34
- Disability, disabilities › intellectual › severe
Inclusion terms
Alternative wording in documentation that is classified to F72.
- IQ 20-25 to 35-40
- Severe mental subnormality
Excludes1 — never code together — inherited from F70-F79
The conditions below can never be reported together with F72 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- borderline intellectual functioning, IQ above 70 to 84 (R41.83)
Code first — inherited from F70-F79
The underlying condition below must be sequenced before F72. F72 describes a manifestation and cannot be the principal or first-listed diagnosis.
- any associated physical or developmental disorders
Excludes2 — not included here — inherited from Chapter 5
The conditions below are not part of F72, but a patient may have both at the same time. When documentation supports it, F72 and the excluded code may both be reported.
- symptoms, signs and abnormal clinical laboratory findings, not elsewhere classified (R00-R99)
How long has F72 existed?
F72 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
