Common Mistakes
Last updated: FY2026 ICD-10-CM Apr update, Apr 1, 2026 through Sep 30, 2026. CMS-HCC V28 is 100% phased in for payment year 2026.
Is L89.132 an HCC code?
Yes. L89.132 maps to Pressure Ulcer of Skin with Partial Thickness Skin Loss under the CMS-HCC V28 risk adjustment model (and Pressure Ulcer of Skin with Partial Thickness Skin Loss 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 L89.132
For L89.132to 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 L89.132 during that encounter, not just copy-forwarded from a problem list.
What This Code Means
L89.132 is the ICD-10-CM diagnosis code for pressure ulcer of right lower back, stage 2. A stage 2 pressure ulcer on the right lower back involving partial-thickness skin loss with blistering or shallow open areas. L89.132 sits in the ICD-10-CM chapter for diseases of the skin and subcutaneous tissue (l00-l99), within the section covering other disorders of the skin and subcutaneous tissue (l80-l99).
Under the CMS-HCC V28 risk adjustment model, L89.132 maps to Pressure Ulcer of Skin with Partial Thickness Skin Loss (HCC 382) with a community, non-dual, aged base RAF weight of 0.000. The V24 model used during the PY2024–PY2025 transition mapped L89.132 the same way and at the same RAF weight. 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.
Stage 2 shows partial-thickness loss; document presence of blisters, abrasion, or shallow crater. Because L89.132 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 L89.132 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Stage 2 shows partial-thickness loss; document presence of blisters, abrasion, or shallow crater
- •Ensure documentation distinguishes this from stage 1 (intact skin) and stage 3 (full-thickness)
Clinical Significance
Stage 2 pressure ulcers of the right lower back represent partial-thickness skin loss at a common pressure point. Early identification and treatment at this stage is critical to prevent progression to more severe stages. The lower back is susceptible to pressure in patients who spend prolonged time in reclined positions, and stage 2 ulcers here may indicate inadequate pressure redistribution strategies.
Documentation Requirements
- ✓Exact anatomical location specified as right lower back
- ✓Stage explicitly documented as stage 2 by the provider
- ✓Wound appearance (intact or ruptured blister, abrasion, shallow crater)
- ✓Wound measurements (length x width)
- ✓Surrounding skin condition
- ✓Contributing factors (positioning, moisture, nutritional status)
- ✓Prevention and treatment plan
