M02.132
BillablePostdysenteric arthropathy, left wrist
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is M02.132 an HCC code?
Yes. M02.132 maps to Bone/Joint/Muscle Infections/Necrosis under the CMS-HCC V28 risk adjustment model (and Bone/Joint/Muscle Infections/Necrosis 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 M02.132
For M02.132to 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 M02.132 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
M02.132 is the ICD-10-CM diagnosis code for postdysenteric arthropathy, left wrist. Joint inflammation and pain in the left wrist that develops as a complication following a dysentery infection. M02.132 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering infectious arthropathies (m00-m02).
Under the CMS-HCC V28 risk adjustment model, M02.132 maps to Bone/Joint/Muscle Infections/Necrosis (HCC 92) with a community, non-dual, aged base RAF weight of 0.209. Under the older V24 model, M02.132 mapped to the same category but with a base RAF weight of 0.482 — V28 recalibrated weights across the entire model. 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.
Verify laterality is documented as left; right wrist requires code M02.131. Because M02.132 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 M02.132 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify laterality is documented as left; right wrist requires code M02.131
- •Document any associated symptoms like swelling or reduced range of motion
Clinical Significance
This code identifies postdysenteric arthropathy specifically affecting the left wrist, a reactive joint inflammation following dysentery that can significantly impact hand function and daily living activities. The chronic nature of this condition requires ongoing medical management and represents a serious post-infectious complication.
Documentation Requirements
- ✓Documented history of dysentery or severe diarrheal infection
- ✓Left wrist joint involvement specifically identified
- ✓Clinical evidence of arthropathy (swelling, pain, decreased range of motion)
- ✓Established timeline between infection and wrist arthritis onset
- ✓Chronic or ongoing nature of joint symptoms documented
- ✓Physical examination findings consistent with arthritis
- ✓Exclusion of other causes of wrist joint disease
Commonly Confused Codes
- •M02.131 — Postdysenteric arthropathy, right wrist (opposite side)
- •M02.139 — Postdysenteric arthropathy, unspecified wrist (when laterality unknown)
- •M00.032 — Staphylococcal arthritis, left wrist (septic arthritis, not reactive)
- •M19.032 — Primary osteoarthritis, left wrist (degenerative, not post-infectious)
- •M25.532 — Pain in left wrist (symptom code, not diagnostic)
