Index to Diseases entry: Depression(acute) (mental)
Each row is a subterm under the entry. Indented rows refine the row above; “see” sends you to another entry. Look the code up in the tabular list before reporting it: the tabular notes can require a more specific or an additional code.

How to read an Index to Diseases entry
- Words in parentheses after a term are nonessential modifiers: they may or may not appear in the record, and they do not change the code.
- Indented subterms are essential modifiers. Each one describes a different site, type or cause, and when the record supports it, the subterm's code replaces the default code.
- “With” and “in” link two conditions. The Official Guidelines presume a causal relationship between conditions linked by “with” in the index unless the provider documents that they are unrelated.
- “See” sends you to another entry that holds the code; “see also” points to another entry that may be useful.
- A code that ends in a dash, such as I50.-, is incomplete: the tabular list gives the characters it still needs.
- Never report a code from the index alone. Find it in the tabular list and apply its includes, excludes, code first, use additional code and 7th-character instructions before you report it.
Once the code is settled, check what it does for payment: the HCC lookup for risk adjustment, the CC/MCC exclusion check for inpatient severity, and the LCD code lookup for local coverage of the service it supports. The guide to ICD-10 diagnosis codes explains the code structure.
For teams evaluating QuickIntell software
Evaluate software for diagnosis coding review
If your team codes diagnoses at volume, review how QuickCode supports qualified coder review of documentation, specificity queries and the billing handoff. Confirm the code sets, settings and reviewer responsibilities during evaluation; a code reference is not a coding determination for a patient.
Optional software evaluation, not payer support or help with an individual claim. For coverage or payment decisions, use the official sources on this page. Do not include patient information in a demo booking or inquiry.
Frequently asked questions
What is the ICD-10 code for depression?
F32.A (Depression, unspecified) is the code the index assigns to "Depression(acute) (mental)" with no further detail. Confirm it in the tabular list before reporting it, because the tabular notes can require a different or additional code.
Which documentation changes the code for depression?
The index lists 50 subterms with their own codes, including agitated(single episode) (F32.2); anxiety (F41.8); anxiety persistent (F34.1); atypical(single episode) (F32.89); atypical(single episode) recurrent episode (F33.8).
