F52.9 ICD-10-CM Code: Unspecified sexual dysfunction not due to a substance or known physiological condition

Coding instructions

Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for F52.9 in the official ICD-10-CM tabular list, quoted as published.

Notes without a marker are published on F52.9 itself; “inherited from” names the category or block whose note applies here.

Coder workflow for F52.9

MedCoder structured workflow — derived from this code’s own official record

Before you code F52.9

1. Unspecified does not mean incorrect. When the record gives no greater specificity, F52.9 may be the appropriate code. Check the record for detail that supports a more specific sibling. An unspecified code is for records that do not provide the detail a more specific code needs; a query, not an assumption, is the route to specificity (Guidelines I.A.9.b, I.B.18).

   ReviewF52.0, F52.1, F52.2, F52.3, F52.4, F52.5, F52.6, F52.8

   See the relationships section · Guide: Other vs unspecified (NEC vs NOS) →

2. F52.9’s title joins a condition with an associated condition or complication. Confirm each component is documented. Where the classification presumes the link through the “with” convention, only a provider statement that the conditions are unrelated defeats it. A combination code is assigned only when it fully identifies the documented conditions; a required second code for the stage, type or manifestation is still reported when the notes ask for it (Guidelines I.B.9, I.A.15).

   Guide: Combination codes →

Choose the right path

1. Does the record document the detail a more specific sibling code needs?
   Yes → Review the specific siblings in this subcategory.
   No → Continue — F52.9 is appropriate when the documentation goes no further.

   ReviewF52.0, F52.1, F52.2, F52.3, F52.4, F52.5, F52.6, F52.8

Consider F52.9. Then confirm the code is valid for the date of service in the Verify section.

Documentation check

The provider’s diagnostic statement

Codes are assigned from the provider’s documented diagnosis, not from clinical criteria, test values or a medication list (Guidelines I.A.19).

The associated condition or complication

Whether the associated condition the title names is documented; the “with” convention presumes some links, and a provider statement that the conditions are unrelated defeats it (Guidelines I.A.15).

Any detail beyond this code’s title

What the record states that a more specific sibling code would capture — or its absence, which itself supports the unspecified code.

Official instructions as workflow

• Excludes2 — not part of F52.9(1 note)

  Coding workflow: The conditions named in this note are not included in F52.9. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

Coding decision scenarios

Pattern scenarios for this code’s structure — decision rules, not clinical cases

Every row is derived from this code’s own record — its title, tabular notes, 7th-character family and same-category siblings — with fixed MedCoder wording; nothing is inferred about a patient. The official notes and guideline text are in the sections each row links to, and they control.

Indexed Clinical Terms (10)

Official source data — entries quoted as published, in the Index’s own lookup phrasing

Clinical term phrases from the official ICD-10-CM Index to Diseases and Injuries that map to this code. These are alphabetic-index entries shown as the Index writes them — lookup phrasing, not necessarily the wording of a final diagnosis.

• Disorder (of), psychogenic NOS, sexual (function)
• Disorder (of), sexual, function, psychogenic
• Disorder (of), sexual, nonorganic
• Dysfunction, psychosexual
• Dysfunction, sexual (due to), female, psychogenic

Verify Before Coding

• Principal-diagnosis restriction. The Medicare Code Editor lists this code as unacceptable as a principal diagnosis: it describes a circumstance influencing health status rather than a current illness or injury being treated. It is valid as a secondary diagnosis.

From the code registry, the Medicare Code Editor, and the MS-DRG Definitions Manual. Check it against a full claim in Claim Check.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name F52.9 or its code family, from the CMS ICD-10-CM tabular instructional notes. Tabular-note edges are stored at the code family level that carries each note.

Referenced by 1 Excludes1 note: N53 — Other male sexual dysfunction (via F52.-).

These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.

Referenced by 1 Excludes2 note: F45 — Somatoform disorders (via F52.-).

These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.
