F50.25
BillableBulimia nervosa, in remission
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is F50.25 an HCC code?
Yes. F50.25 maps to Personality Disorders and Dissociative Disorders under the CMS-HCC V28 risk adjustment model.
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 F50.25
For F50.25 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 F50.25 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
F50.25 is the ICD-10-CM diagnosis code for bulimia nervosa, in remission. A bulimia nervosa eating disorder that is currently in remission or recovery. F50.25 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering behavioral syndromes associated with physiological disturbances and physical factors (f50-f59).
Under the CMS-HCC V28 risk adjustment model, F50.25 maps to Personality Disorders and Dissociative Disorders (HCC 153) with a community, non-dual, aged base RAF weight of 1.241. F50.25 was not retained as a payment HCC under the older V24 model, so V28 introduced or recategorized it during the 2024–2026 phase-in. 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.
Only use when provider explicitly documents remission or recovery status. Because F50.25 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 F50.25 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Only use when provider explicitly documents remission or recovery status
- •Ensure the patient is not currently experiencing active binge-purge cycles
Clinical Significance
Bulimia nervosa involves recurrent episodes of binge eating followed by inappropriate compensatory behaviors (self-induced vomiting, laxative/diuretic misuse, fasting, excessive exercise) in a patient at normal or above-normal weight. In remission indicates prior full criteria were met but the patient has sustained cessation of binge/purge behaviors. Unlike anorexia nervosa, patients with bulimia are not significantly underweight, which can make the condition less visually apparent.
Documentation Requirements
- ✓Recurrent episodes of binge eating (consuming objectively large amounts of food with sense of loss of control)
- ✓Recurrent inappropriate compensatory behaviors to prevent weight gain (No current binge/purge episodes)
- ✓Binge eating and compensatory behaviors occur at least once per week for three months
- ✓Self-evaluation unduly influenced by body shape and weight
- ✓Disturbance does not occur exclusively during episodes of anorexia nervosa (patient is NOT significantly underweight)
