Buddy Documentation Tip

HCC Buddy guidance

Documentation of manic symptoms lasting at least one week (elevated mood, increased energy, decreased sleep, pressured speech, flight of ideas, grandiosity, increased goal-directed activity)

Confirmation that psychotic features (hallucinations, delusions) are absent

Attempt to determine severity level through provider query

Assessment of functional impairment during the episode

Audit Caution

HCC Buddy guidance

Not querying the provider about the severity level to move from F30.10 to a more specific code (F30.11-F30.13)

Confusing a standalone manic episode (F30) with bipolar disorder (F31) — F30 is used for single or first episodes before a bipolar pattern is established

Coding hypomania (F30.8 or F31.0) instead of a full manic episode when documentation supports full mania

Using F30.10 when psychotic features are present — F30.2 should be used instead

Common Mistakes

HCC Buddy guidance

F30.11 — Manic episode, MILD when severity is specified as mild

F30.12 — Manic episode, MODERATE when severity is specified as moderate

F30.13 — Manic episode, SEVERE without psychotic symptoms when severity is specified as severe

F30.2 — Manic episode WITH psychotic symptoms; verify absence of psychotic features before using F30.10

Is F30.10 an HCC code?

Yes. F30.10 (Manic episode without psychotic symptoms, unspecified) 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: F30.10 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.

RxHCCHCC 131, Bipolar Disorders

Not separately weighted

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 F30.10

For F30.10, 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

F30.10 is the ICD-10-CM diagnosis code for manic episode without psychotic symptoms, unspecified. A manic episode where a person experiences elevated mood, increased energy, and racing thoughts without experiencing hallucinations or delusions, with severity level not specified. F30.10 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, F30.10 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.

Specify the severity level (mild, moderate, severe) when documented to use F30.11, F30.12, or F30.13. For F30.10, 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 F30.10 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Specify the severity level (mild, moderate, severe) when documented to use F30.11, F30.12, or F30.13
•Document the duration of the manic episode and functional impairment to support severity assessment

Clinical Significance

Manic episode without psychotic symptoms, unspecified severity captures an acute manic episode where the patient has elevated mood, increased energy, and reduced need for sleep, but without psychotic features such as hallucinations or delusions. The unspecified severity represents a documentation gap — the provider should ideally specify mild, moderate, or severe. Manic episodes require active psychiatric management and often lead to hospitalization, reflecting the clinical urgency of this diagnosis.

Documentation Requirements

✓Documentation of manic symptoms lasting at least one week (elevated mood, increased energy, decreased sleep, pressured speech, flight of ideas, grandiosity, increased goal-directed activity)
✓Confirmation that psychotic features (hallucinations, delusions) are absent
✓Attempt to determine severity level through provider query
✓Assessment of functional impairment during the episode
✓Current medication management (mood stabilizers, antipsychotics)
✓Safety assessment including risky behaviors, suicidality

Commonly Confused Codes

•F30.11: Manic episode, MILD when severity is specified as mild
•F30.12: Manic episode, MODERATE when severity is specified as moderate
•F30.13: Manic episode, SEVERE without psychotic symptoms when severity is specified as severe
•F30.2: Manic episode WITH psychotic symptoms; verify absence of psychotic features before using F30.10
•F31.10: Bipolar disorder, current episode manic without psychotic features is different from a standalone manic episode
