F30.8
BillableOther manic episodes
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is F30.8 an HCC code?
Yes. F30.8 maps to Bipolar Disorders under the CMS-HCC V28 risk adjustment model (and Major Depressive, Bipolar, and Paranoid Disorders under V24).
HCC Category Mapping
RAF weights shown are the community, non-dual, aged base weights from the CMS risk adjustment model file. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.
MEAT Criteria for F30.8
For F30.8 to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically — it has to be re-documented and supported each calendar year.
- MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
- EEvaluate: test results, medication response, or physical findings reviewed by the provider
- AAssess: explicit mention in the assessment or plan with acknowledgment of status
- TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis
Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed F30.8 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
F30.8 is the ICD-10-CM diagnosis code for other manic episodes. A manic episode that doesn't fit the standard categories, characterized by an abnormally elevated or irritable mood with increased energy and activity that lasts at least one week. F30.8 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering mood [affective] disorders (f30-f39).
Under the CMS-HCC V28 risk adjustment model, F30.8 maps to Bipolar Disorders (HCC 154) with a community, non-dual, aged base RAF weight of 0.265. Under the older CMS-HCC V24 model, F30.8 maps to Major Depressive, Bipolar, and Paranoid Disorders (HCC 59) with a community, non-dual, aged base RAF weight of 0.309. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition.
Use this code when the manic episode presentation is atypical or doesn't meet criteria for other specified manic episode codes. Because F30.8 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for F30.8 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code when the manic episode presentation is atypical or doesn't meet criteria for other specified manic episode codes
- •Document the specific features and duration of the manic symptoms to support medical necessity
Clinical Significance
Other manic episodes is used for manic presentations that do not fit standard categories, which may include hypomania within a single-episode context. This residual code captures atypical manic presentations that still require clinical attention and treatment. The code carries the same HCC weight as specified manic episodes, ensuring risk adjustment credit for these less common but clinically significant presentations.
Documentation Requirements
- ✓Documentation of manic or hypomanic symptoms by a qualified provider
- ✓Description of the specific features that make this an atypical or 'other' manic presentation
- ✓Explanation of why standard manic episode codes (F30.10-F30.4) do not apply
- ✓Assessment of functional impact and severity
- ✓Current treatment plan and medication regimen
- ✓Monitoring schedule and escalation criteria
Commonly Confused Codes
- •F30.10-F30.13 — Standard manic episodes at specified severity levels should be used when criteria are met
- •F31.0 — Bipolar disorder, hypomanic episode is used within an established bipolar pattern
- •F34.0 — Cyclothymic disorder involves chronic low-level mood cycling, not discrete episodes
- •F30.9 — Manic episode, unspecified is for when the type cannot be determined
- •F34.81 — Disruptive mood dysregulation disorder is a childhood diagnosis, not mania
