Audit Caution

HCC Buddy guidance
Using F30.8 when a standard manic episode code is appropriate with proper documentation
Confusing hypomania in a single-episode context with bipolar hypomania
Not documenting the atypical features that warrant this 'other' code
Using this code as a shortcut to avoid specifying the manic episode severity

Common Mistakes

HCC Buddy guidance
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

Is F30.8 an HCC code?

Yes. F30.8 (Other manic episodes) maps to HCC 154, Bipolar Disorders without Psychosis under the CMS-HCC V28 risk adjustment model, with a source-labeled community non-dual aged reference coefficient of 0.351. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes. It is billable for payment year 2026.

Coder answer: F30.8 is billable and maps to V28 HCC 154, Bipolar Disorders without Psychosis. Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

These are source-labeled model coefficients, not member totals. A category may still be removed by hierarchy or model cleanup rules. Weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member context, hierarchy and cleanup rules, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains available for historical review.

MEAT review for F30.8

For F30.8, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule.

  • 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

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 without Psychosis (HCC 154) with a source-labeled community, non-dual, aged reference coefficient of 0.351. For CY2026 non-PACE Medicare Advantage, CMS uses 100% of the 2024 CMS-HCC model (V28). PACE uses a separate model blend. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes.

Use this code when the manic episode presentation is atypical or doesn't meet criteria for other specified manic episode codes. For F30.8, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule. 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, source-labeled coefficient references, 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.

F30.8 maps to CMS-HCC V28 category 154, Bipolar Disorders without Psychosis. See the ICD-10 to HCC mapping hub for how the V28 crosswalk works. The mapping identifies a payment HCC category for F30.8. Review its source-labeled HCC coefficient above, check the RAF Calculator with complete member context for CMS-HCC V28 PY2026, and confirm the documentation the chart needs before the code is submitted. HCC Buddy shows no RAF score unless every required source and calculation check passes.
